When we announced the Workflow Development Kit (WDK) at Ship AI just over a month ago, we wanted it to reflect our Open SDK Strategy, allowing developers to build with any framework and deploy to any platform.
At launch, WDK supported Next.js and Nitro. Today it works with eight frameworks, including SvelteKit, Astro, Express, and Hono, with TanStack Start and React Router in active development. This post explains the pattern behind those integrations and how they work under the hood.
Vercel now supports lifespan events for FastAPI apps. This allows you to define logic that can execute on startup and graceful shutdown—such as managing database connections or flushing external logs.
Deploy FastAPI on Vercel or visit the FastAPI on Vercel documentation.
Vercel now provides a unified dashboard that surfaces any security issues requiring action from your team. When a critical vulnerability or security-related task is detected, the dashboard automatically groups your affected projects and guides you through the steps needed to secure them.
This view appears as a banner whenever action is required, and can be accessed anytime through the dashboard search.
Most CVEs are handled automatically through WAF rules and other protections, but when user action is needed, they will appear here.
Automatic detection of security vulnerabilities that require user intervention - When the platform identifies a vulnerability or configuration that cannot be fully mitigated by Vercel’s autonomous protections, it’s surfaced here with clear instructions.
Project grouping based on required actions - Current categories include unpatched dependencies, manual fix required, unprotected preview deployments. Additional groups will appear over time as new protections and checks are added.
Support for both automated remediation - When possible, Vercel Agent offers one-click automated upgrades and PRs.
Support for manual remediation - For cases requiring manual updates or where GitHub access isn’t available, we provide direct instructions such as: npx fix-react2shell-next
The unified dashboard helps teams act quickly during critical moments, consolidate required fixes in one place, and maintain a stronger security posture across all projects.
Explore the dashboard to view any required updates.
Vercel Agent now detects vulnerable packages in your project, and automatically generates pull requests with fixes to upgrade them to patched versions.

Remend is a new standalone package that brings intelligent incomplete Markdown handling to any application.
Previously part of Streamdown's Markdown termination logic, Remend is now a standalone library (npm i remend) you can use in any application.
AI models stream Markdown token-by-token, which often produces incomplete syntax that breaks rendering. For example:
Unclosed fences
Half-finished bold/italic markers
Unterminated links or lists
Without correction, these patterns fail to render, leak raw Markdown, or disrupt layout:
Remend automatically detects and completes unterminated Markdown blocks, ensuring clean, stable output during streaming.
As the stream continues and the actual closing markers arrive, the content seamlessly updates, giving users a polished experience even mid-stream.
It works with any Markdown renderer as a pre-processor. For example:
Remend powers the markdown rendering in Streamdown and has been battle-tested in production AI applications. It includes intelligent rules to avoid false positives and handles complex edge cases like:
Mathematical expressions with underscores in LaTeX blocks
Product codes and variable names with asterisks/underscores
List items with formatting markers
Nested brackets in links
To get started, either use it through Streamdown or install it standalone with:
See the React2Shell security bulletin for the latest updates.
A critical-severity vulnerability in React Server Components (CVE-2025-55182) affects React 19 and frameworks that use it, including Next.js (CVE-2025-66478). Under certain conditions, specially crafted requests could lead to unintended remote code execution.
We created new rules to address this vulnerability and quickly deployed to the Vercel WAF to automatically protect all projects hosted on Vercel at no cost. However, do not rely on the WAF for full protection. Immediate upgrades to a patched version are required. We also worked with the React team to deliver recommendations to the largest WAF and CDN providers.
We still strongly recommend upgrading to a patched version regardless of your hosting provider.
Applications using affected versions of the React Server Components implementation may process untrusted input in a way that allows an attacker to perform remote code execution. The vulnerability is present in versions 19.0, 19.1.0, 19.1.1, and 19.2.0 of the following packages: :
react-server-dom-parcel (19.0.0, 19.1.0, 19.1.1, and 19.2.0)
react-server-dom-webpack (19.0.0, 19.1.0, 19.1.1, and 19.2.0)
react-server-dom-turbopack (19.0.0, 19.1.0, 19.1.1, and 19.2.0)
These packages are included in the following frameworks and bundlers:
Next.js with versions ≥14.3.0-canary.77, ≥15 and ≥16
Other frameworks and plugins that embed or depend on React Server Components implementation (e.g., Vite, Parcel, React Router, RedwoodSDK, Waku)
After creating mitigations to address this vulnerability, we deployed them across our globally-distributed platform to quickly protect our customers. We still recommend upgrading to the latest patched version.
Updated releases of React and affected downstream frameworks include hardened handling of user inputs to prevent unintended behavior. All users should upgrade to a patched version as soon as possible. If you are on Next.js 14.3.0-canary.77 or a later canary release, downgrade to the latest stable 14.x release.
React: 19.0.1, 19.1.2, 19.2.1
Next.js: 15.0.5, 15.1.9, 15.2.6, 15.3.6, 15.4.8, 15.5.7, 15.6.0-canary.58, 16.0.7
Frameworks and bundlers using the aforementioned packages should install the latest versions provided by their respective maintainers.
Thanks to Lachlan Davidson for identifying and responsibly reporting the vulnerability, and the Meta Security and React team for their partnership.

Every year, Black Friday and Cyber Monday reveal how people shop, browse, and discover products at global scale. For Vercel, the weekend doesn't require a different operating mode. The platform behaves the same way it does every day, only with higher traffic volume.
A live dashboard showed the traffic as it played out.
This year, traffic reached more than 115.8 billion total requests, reflecting 33.6% year-over-year growth with consistent performance throughout the events.
The traffic shape told a familiar story. Requests dipped on Thanksgiving as people stepped away from screens, then surged on Black Friday, stayed elevated through the weekend, and built into a second wave on Cyber Monday.
These rhythms played out across every major geography, and the platform adapted continuously without configuration changes or manual intervention.
Below is a snapshot of what the weekend looked like.
The team behind Gel Data is joining Vercel to help us invest in the Python ecosystem. Led by Python core developer Yury Selivanov and contributor Elvis Pranskevichus, they will bring world-class support for Python on the AI Cloud.
On average, the deploy step is now 17% faster, reducing total time to go live by 1.67 seconds. Projects with a large number of functions will see even greater improvements, with up to 2.8 seconds saved on average.
During the deploy step, Vercel uploads static assets, provisions and uploads like Vercel Functions, processes routing metadata, and prepares the deployment to receive traffic. This phase is now faster due to reduced idle time and increased concurrency across these operations.

We recently released v0 for iOS, Vercel’s first mobile app. As a company focused on the web, building a native app was new territory for us.
Our goal was to build an app worthy of an Apple Design Award, and we were open-minded on the best tech stack to get there. To that end, we built dozens of iterations of the product prior to our public beta. We experimented with drastically different tech stacks and UI patterns.
Today we're open-sourcing Workflow Builder, a complete visual automation platform powered by the Workflow Development Kit (WDK).
The project includes a visual editor, execution engine, and infrastructure, giving you what you need to build your own workflow automation tools and agents. Deploy it to Vercel and customize it for your use case.
At Vercel, we believe security should be intuitive, not intimidating. The best security tool is the one that's actually used. It should be clear, useful, and never in the way.
But that's not always the norm. Security tooling can often feel like a tradeoff against shipping velocity. When UX is an afterthought, teams leave tools off or in "logging mode" forever, even when risks are high.
That's why we've redesigned the Vercel Firewall experience from the ground up. The new UI helps you see more, do more, and feel confident in your app's resilience to attacks.
Vercel now supports commit verification, letting you protect your deployments by requiring commits to be cryptographically verified before they’re deployed from GitHub.
Enable it for GitHub-connected projects in your project settings.
Learn more about commit signing and verification on GitHub or read more about the setting in our docs.
Convex is now available on the Vercel Marketplace, giving developers an easy way to add a real-time backend to any Vercel project. You can create and connect a Convex project directly from the Vercel dashboard and get a fully configured backend without manual setup.
With the new integration, you can:
Provision a Convex project directly from Vercel dashboard
Manage accounts and billing in one place
Get real-time data sync with built-in caching and consistency
Use Convex’s data model and functions alongside Vercel’s full developer workflow
Install Convex from the Marketplace and start building with a fully connected backend in just a few clicks.
Multiple npm packages from various web services were compromised through account takeover/developer compromise. A malicious actor was able to add a stealthy loader to the package.json file that locates the Bun runtime, silently installs, then executes a malicious script.
Our investigation has shown that no Vercel environment was impacted and we are notifying a small set of customers with affected builds.
Vercel has taken immediate steps to address this for our customers. As an initial step, we reset the cache for projects that pulled in any of the vulnerable packages while we continue to investigate whether any loaders successfully ran.
As of this publication, no Vercel-managed systems or internal build processes have been impacted.
Preliminary analysis identified a limited set of Vercel customer builds referencing the compromised packages.
Impacted customers are being contacted directly with detailed mitigation steps.
We will continue to issue updates throughout our investigation.
You can now configure advanced sampling rules when exporting data to a third-party observability tool when using Vercel Drains.

In April, we launched the Vercel Open Source Program to give maintainers the resources, credits, and support they need to ship faster and scale confidently. The first group joined through our spring 2025 cohort.
Today we are welcoming the fall 2025 cohort.
From AI-native apps and developer infrastructure to design systems and creative tooling, open-source builders continue to amaze us. Meet the creators and explore their projects.
AI has transformed how we write code. The next transformation is how we run it.
At Vercel, we’re building self-driving infrastructure that autonomously manages production operations, improves application code using real-world insights, and learns from the unpredictable nature of production itself.
Our vision is a world where developers express intent, not infrastructure. Where ops teams set principles, not individual configurations and alerts. Where the cloud doesn’t just host your app, it understands, optimizes, and evolves it.
Vercel Agent investigations are now included in Observability Plus, adding 10 investigations to every billing cycle at no extra cost to your subscription.

Vercel Image Optimization dynamically transforms source images to reduce file size while maintaining high quality on the visitor's browser.
You can now invalidate the CDN cache by providing a source image.
This feature marks all transformed images derived from that source image as stale. The next request serves stale content instantly while revalidation happens in the background, with no latency impact for users.
There are several ways to invalidate a source image:
In addition to invalidating by source image, you can also delete by source image if the origin is gone. Deleting the cache can increase latency while new content is generated, or cause downtime if your origin is unresponsive. We recommend you use with caution.
This is available on all plans using the new image optimization price.
Learn more about cache invalidation.
We have launched improvements to the Vercel Firewall UI, simplifying your application security monitoring and analysis. Vercel Firewall includes the System firewall and DDoS mitigations, Web Application Firewall, and Bot Management capabilities.

Vendor lock-in matters when choosing a cloud platform. Cloud platforms can lock you in by requiring you to build against their specific primitives. Vercel takes a different approach: you write code for your framework, not for Vercel.
On AWS, you configure Lambda functions, NAT Gateways, and DynamoDB tables. On Cloudflare, you write Workers, use KV stores, Durable Objects, and bind services with Worker Service Bindings. These primitives only exist with that vendor, which means migrating to another platform requires rewriting your application architecture.
Too often, cloud platforms make these choices for you. They define proprietary primitives, APIs, and services that pull your code deeper into their ecosystem until leaving becomes impractical.
At Vercel, we believe the opposite approach creates better software and a healthier web. We want developers to stay because they want to, not because they have to. That means building open tools, embracing standards, and ensuring your code remains portable no matter where it runs.
So Vercel works differently. It interprets your framework code and provisions infrastructure automatically. Your application does not need to know it runs on Vercel. You do not need to import Vercel modules or call Vercel APIs. This is framework-defined infrastructure.
Vercel's AI Gateway now supports fallback models for when models fail or are unavailable. In addition to safeguarding against provider-level failures, model fallbacks can help with errors and capability mismatches between models (e.g., multimodal, tool-calling, etc.).
Fallback models will be tried in the specified order until a request succeeds or no options remain. Any error, such as context limits, unsupported inputs, or provider outages, can trigger a fallback. Requests are billed based on the model that completes successfully.
This example shows an instance where the primary model does not support multimodal capabilities, falling back to models that do. To use, specify the model fallbacks in models within providerOptions:
To have pre-defined provider routing in addition to model routing, specify both models and providers (order or only) in providerOptions:
AI Gateway also includes built-in observability, Bring Your Own Key support, and supports OpenAI-compatible API.
Vercel detects and supports TanStack Start applications, a full-stack framework powered by TanStack Router for React and Solid.
Create a new TanStack Start app or add nitro() to vite.config.ts in your existing application to easily deploy your projects:
TanStack Start apps on Vercel use Fluid compute with Active CPU pricing by default. This means your TanStack Start app will automatically scale up and down based on traffic, and you only pay for what you use, not for idle function time.

AI lab Nous Research made Hermes, their open-source language model, free for one week to increase accessibility. Within days, automated scripts overwhelmed the service with fake accounts performing high-volume inference requests across thousands of accounts to bypass rate limits.
Despite having Cloudflare Turnstile in place, bulk signups continued. The abuse led to wasted inference compute and inflated identity provider bills. After the promotion ended, Nous realized that before reintroducing any kind of free tier, it needed a stronger layer of bot protection.
HTTPS connections to the Vercel network are now secured with post-quantum cryptography.
Most web encryption today could be broken by future quantum computers. While this threat isn’t immediate, attackers can capture encrypted traffic today and decrypt it later as quantum technology advances.
Vercel now supports post-quantum encryption during TLS handshakes, protecting applications against these future risks. Modern browsers will automatically use it with no configuration or additional cost required.
Read more about encryption and how we secure your deployments.

We’ve introduced the Vercel Sandbox CLI, a command-line interface for managing isolated compute environments. Built on the familiar Docker CLI model, developers can now:
Create and run sandboxes for Node.js (node22) or Python (python3.13) workloads.
Execute commands inside existing sandboxes.
Copy files between local and remote environments.
List, stop, and remove sandboxes across projects and teams.
Run interactively with support for --tty, --interactive, and --publish-port for port forwarding.
Automate workflows via authentication tokens, environment variables, and timeouts.
Full reference now available in the Sandbox CLI docs.
AI Gateway is a Node.js service for connecting to hundreds of AI models through a single interface. It processes billions of tokens per day. The secret behind that scale is Fluid.
Agents present incredible promise for increased productivity and higher quality outcomes in enterprises. Companies are already using them to streamline customer support, code reviews, and sales operations.
When building custom internal agents, the challenge isn't whether AI can create value, it's identifying the problems it's ready to solve today, at a cost that makes sense for the business.
At Vercel, we are going through the same AI transformation as our customers. We use our own products to build agents that help us move faster and spend more time on meaningful work.
After months of experimentation, we’ve turned our learnings into a repeatable methodology for finding and investing in AI projects that have the highest likelihood of creating significant business impact.

A medium-severity security vulnerability in Nuxt DevTools was responsibly disclosed, and has been fixed for version 2.6.4. This issue may have allowed Nuxt auth token extraction via XSS under certain configurations.
Nuxt DevTools users are encouraged to upgrade to the latest version. Read more details below.
A vulnerability chain in Nuxt DevTools allows remote code execution in development environments through a combination of cross-site scripting (XSS), authentication token exfiltration, and path traversal.
The vulnerability exists in the DevTools authentication page where error messages are rendered without proper sanitization, enabling DOM-based XSS. An attacker can exploit this to steal authentication tokens and leverage a path traversal vulnerability in the WebSocket message handler to write arbitrary files outside the intended directory, leading to remote code execution when configuration files are overwritten.
The XSS was resolved by displaying errors as textContent instead of innterHTML in:
Nuxt DevTools 2.6.4
Avoid publicly exposing Nuxt DevTools or running Nuxt in production using Dev mode
Thanks to @yuske for responsible disclosure.
A low-severity security vulnerability in Vercel's AI SDK was responsibly disclosed, and has been fixed for 5.0.52, 6.0.0-beta.* The issue may have allowed users to bypass filetype whitelists when uploading files.
Vercel customers are encouraged to upgrade to the latest version. Read more details below.
Vulnerability in Vercel's AI SDK prompt conversion pipeline where improper URL-to-data mapping allows attackers to substitute arbitrary downloaded bytes for different supported URLs within the same prompt. The vulnerability occurs in the convert-to-language-model-prompt.ts file when filtering downloaded results could cause index misalignment between the downloadedFiles array and the original plannedDownloads array.
When processing mixed supported and unsupported URLs, the filtering operation removes null entries for supported URLs, causing the remaining downloaded data to be incorrectly associated with different URL keys. This results in bytes from an unsupported URL being mapped to a supported URL slot, allowing attackers to inject arbitrary content while bypassing URL-based trust and content validation mechanisms.
This affects most methods that accepted images or files as inputs, unless explicit data validation was implemented outside of the SDK. Namely the generateText() and streamText() functions.
The issue was resolved by mapping files before filtering out empty ones to retain the correct index in:
5.0.52
6.0.0-beta.*
Implementing custom filetype validation logic outside of the SDK.
Thanks to @aphantom for responsible disclosure.
Skew Protection helps ensure that requests for a user's session are consistently routed to the same deployment, even when new versions are being rolled out.

On October 29 at 9:44am, BotID Deep Analysis detected an unusual spike in traffic patterns across one of our customer's projects. Traffic increased by 500% above normal baseline. What made this particularly interesting wasn't just the volume increase. The spike appeared to be coming from legitimate human users.
Our team immediately began investigating and reached out to the customer to discuss what appeared to be an influx of bot traffic cleverly disguised as human activity. But before we could even complete that conversation, something remarkable happened: Deep Analysis, powered by Kasada’s machine learning backend, had already identified the threat and adapted to correctly classify it.
Vercel is reimagining incident response for the agentic age.
At Ship AI, we launched Vercel Agent Investigations in Public Beta, a new skill of Vercel Agent that automatically detects issues in your application, conducts root cause analysis, and provides actionable remediation plans to resolve incidents faster.

The next era of enterprise technology will be defined by shortening the distance between idea and impact. At Vercel we help companies move faster, turning velocity into measurable business outcomes by anticipating customer needs and owning results end-to-end.
To help us lead in this new era, David Totten is joining Vercel as VP of Global Field Engineering. David brings two decades of experience building and scaling technical teams, and he'll lead a unified organization that includes Sales Engineering, Developer Success, Professional Services, and Customer Support Engineering.
Earlier this year we introduced the foundations of the AI Cloud: a platform for building intelligent systems that think, plan, and act. Last week at Ship AI, we showed what comes next.
We launched new SDKs, infrastructure, and open source templates that make building production-ready agents as intuitive as building a standard feature. You can now define, deploy, and operate intelligent workflows on the same platform that powers your apps.
Whether you're building your first agent or delivering it to millions of users, these releases make AI development as accessible and scalable as web development.
We're excited to announce that AI Chat is now live within the Vercel docs along with a subtle design overhaul. You can now get instant, conversational assistance directly on all docs pages.

Server Action Name is available in the Firewall for all plans at no additional cost. Read the docs to learn more.
Building agents should feel like shaping an idea rather than fighting a maze of code or infrastructure.
And we've seen this story before. A decade ago, the web moved from hand‑rolled routing and homegrown build scripts to opinionated frameworks and a platform that understood what developers were trying to do. Velocity went up, quality followed, and a generation of products appeared as if overnight.
AI is following the same arc, but the stakes and surface area are larger because what you build is no longer a set of pages. It is a system that intelligently reasons, plans, and acts.
Built on the foundations of Framework-defined Infrastructure, Vercel AI Cloud provides the tooling, infrastructure primitives, developer experience, and platform to bypass the complexity. You focus entirely on what you're building, with confidence in what's powering it under the hood.
Agents and agentic AI give developers new ways to move faster and build better. They create connected, autonomous systems that continuously improve applications and raise the bar for speed and quality.
But typically, integrating AI services means managing separate dashboards, billing systems, and authentication flows for each tool. A team using three different AI services might waste hours wiring up each integration before writing a single line of application code.
Today, we're introducing the AI agents and services category to the Vercel marketplace. You can now add AI-powered workflows to your projects through native Vercel integrations with unified billing, observability, and installation flows built into the platform.
Building reliable software shouldn't require mastering distributed systems.
Yet for developers building AI agents or data pipelines, making async functions reliable typically requires message queues, retry logic, and persistence layers. Adding that infrastructure often takes longer than writing the actual business logic.
The Workflow Development Kit (WDK) is an open source TypeScript framework that makes durability a language-level concept. It runs on any framework, platform, and runtime. Functions can pause for minutes or months, survive deployments and crashes, and resume exactly where they stopped.
The same ease of use you expect from Vercel, now extended to your backends.
Since we introduced the AI Cloud at Vercel Ship, teams have been building AI applications that go beyond simple prompt-to-response patterns. These apps orchestrate multi-step workflows, spawn sub-agents, and run processes that take hours or days. They need backends that process data, run inference, and respond to real-time events.
You can now deploy the most popular Python and TypeScript backend frameworks with zero configuration. Vercel reads your framework and automatically provisions the infrastructure to run it.
We're launching Vercel Agent, an AI teammate for your development workflow. Vercel Agent uses AI, deep platform expertise, your application code, and telemetry data from across Vercel to help you ship faster with higher quality.
Starting today, Vercel Agent is available in Public Beta with two core skills: Code Review and Investigations.
The Vercel Marketplace now includes a dedicated AI Agents & Services category, making it easier for developers to integrate AI-powered automation, observability, and infrastructure directly into their projects.
This category introduces native support for agentic integrations with unified authentication, provisioning, and billing across providers, all within the Vercel platform.

Workflow Development Kit, a framework for building durable, long-running processes, is now in public beta.
Workflow Development Kit brings durability, reliability, and observability to async JavaScript so you can build apps and AI agents that suspend, resume, and maintain state with ease.
Turning functions into durable workflows is made simple by the "use workflow" directive:
Key highlights include:
Reliability by simply adding "use workflow" to make async functions durable. No manual wiring of queues, no schedulers, no YAML.
Mark Steps to denote with "use step". Retries are automatic.
Durability. Call sleep to pause without holding compute, then resume in place.
Built-in observability. Traces, logs, and metrics for every run. Pause, replay, and time travel while debugging.
No lock-in. Develop locally and deploy to Vercel or any other cloud.
Learn more about Workflow or read the documentation.

At Vercel, our philosophy is to take ownership for, not blame, our vendors. Customers use our services to gain velocity, reliability, and ship wonderful products. Whether we picked A or B as one of the components of our “circuit design” is entirely our responsibility.
Vercel is fully accountable for this incident, even if it's now public that it was triggered by the unexpected outage of AWS us-east-1 (called iad1 region). Vercel uses AWS infrastructure primitives, is part of the AWS marketplace, offers secure connectivity to AWS services, and shares a long history with AWS of pioneering serverless computing.
To our customers, Vercel is unequivocally responsible for this outage.
Our goal is to simplify the cloud and offer its best version. Through framework-defined infrastructure, we help developers focus on the application layer by deploying global infrastructure resources that are highly optimized. We operate our Compute, CDN, and Firewall services across 19 AWS regions, terminating and securing traffic in 95 cities and 130+ global points of presence.
Yesterday, we fell short of this promise. While a significant amount of traffic was still served, and we shielded customers from the exposure to a single global point of failure, our ambition is to enable customers to never drop a single request, even in the event of an outage.
You can now extend the duration of a running Vercel Sandbox using the new extendTimeout method.
This lets long-running sandboxes stay active beyond their initial timeout, making it easier to support workflows like chained agentic tasks or multi-step code generation that take longer than expected.
You can extend the timeout multiple times until the maximum runtime for your plan is reached.
Pro and Enterprise plans support up to 5 hours, with the Hobby plan supporting up to 45 minutes.
Teams using microfrontends can now visit all routes from any domain in the microfrontends group, enabling teams to test their full site experience without broken links or missing pages.
Previously, the microfrontend group's root domain would be the only one to serve the paths hosted by child microfrontends. Now, preview links between all microfrontends projects automatically serve all routes in the group.
With this new feature:
Preview links on child microfrontends now route paths to other microfrontends in the group, eliminating 404s.
Deployments built from the same commit or branch automatically link to each other, making it easier to test changes in monorepos.
Fallback routing ensures that requests to microfrontends not built on the same branch are still resolved.
This feature is enabled by default for all new microfrontends, and will be rolling out slowly for existing teams.
Learn more or get started with microfrontends today.
Vercel now supports NestJS applications, a popular framework for building efficient, scalable Node.js server-side applications, with zero-configuration.
Backends on Vercel use Fluid compute with Active CPU pricing by default. This means your NestJS app will automatically scale up and down based on traffic, and you only pay for what you use.
Deploy NestJS on Vercel or visit the NestJS on Vercel documentation
Braintrust is now available on the Vercel Marketplace, bringing AI evaluation and observability directly into the Vercel workflow.
With this new integration, developers can automatically stream traces and evaluation data from Vercel to Braintrust with just a few clicks, gaining full visibility into model quality and user experience in real time.
With Braintrust on Vercel Marketplace, you can:
Ship agents and AI features with built-in evaluation and observability
Run evals and monitor model quality in production
Benchmark and compare performance across LLMs
Explore the template to deploy the example today, with easy setup and unified billing.
Every generation of software moves interfaces closer to where people think and work. Terminals gave way to GUIs. GUIs gave way to browsers. And now, the interface is language itself. Conversation has become the most natural way to build, explore, and decide.
At the center of this shift is a new pattern: the AI agent. Today, software doesn’t have to wait for clicks or configuration, but understands user intent, reason about it, and takes action.
The question for enterprises isn’t if they’ll adopt agents, but where those agents will live. Our answer: where work already happens.
That’s why Vercel and Salesforce are partnering to help teams build, ship, and scale AI agents across the Salesforce ecosystem, starting with Slack. Together, we’re bringing the intelligence and flexibility of the Vercel AI Cloud to the places teams collaborate every day.
When OpenAI announced the Apps SDK with Model Context Protocol (MCP) support, it opened the door to embedding web applications directly into ChatGPT. But there's a significant difference between serving static HTML in an iframe and running a full Next.js application with client-side navigation, React Server Components, and dynamic routing.
This is the story of how we bridged that gap. We created a Next.js app that runs natively inside ChatGPT's triple-iframe architecture, complete with navigation and all the modern features you'd expect from a Next.js application.
As AI reshapes how software is built and deployed, the surface area for attacks is growing rapidly. Developers are shipping faster than ever, and we’re seeing new code paths, new threat models, and new vulnerabilities.
That’s why I’m excited to share that Talha Tariq is joining Vercel as our CTO of Security.
Talha brings deep expertise in security at scale, having served as CISO & CIO at HashiCorp for seven years before becoming CTO (Security) at IBM following its acquisition. There, he oversaw security across all IBM divisions including software, AI, and post-quantum cryptography.
For teams on Vercel, Black Friday is just another Friday. The scale changes, but your storefronts and apps stay fast, reliable, and ready for spikes in traffic.
Many of the optimizations required for peak traffic are already built into the platform. Rendering happens at the edge, caching works automatically, and protection layers are on by default.
What’s left for teams is refinement: confirming observability is set up, tightening security rules, and reviewing the dashboards that matter most.
Last year, Vercel created a live Black Friday Cyber Monday dashboard that showcased our scale in real-time, showing the spikes. Overall, from Friday to Thursday, Vercel served 86,702,974,965 requests across its network, reaching a peak of 1,937,097 requests per second.
Helly Hansen, a major technical apparel brand, entered the weekend with this confidence. Before the event, they moved from client-heavy rendering to Vercel’s CDN and saw:
You can now use Vercel Drains to send traces and logs from your projects to your preferred Marketplace observability providers with native integrations, including Braintrust, Dash0, Statsig, and Kubiks with more providers coming soon.
This integration allows developers to stream traces and evaluation data from Vercel directly into these providers for observability, debugging, and performance monitoring.
The Trace Drain API extends Vercel’s observability surface to the Marketplace ecosystem, allowing providers to:
Deliver rich visibility into performance and debugging data
Integrate natively with logging, and analytics tools through Vercel
Build tighter feedback loops between deployments and infrastructure insights
Offer customers a fully connected experience without manual setup
This update gives teams more flexibility to use their preferred observability tools while maintaining a single, unified developer experience inside Vercel.
Try it out or learn more about this update available to Pro and ENT customers.
You can now access Anthropic's latest model, Claude Haiku 4.5 using Vercel's AI Gateway with no other provider accounts required. Haiku 4.5 matches Sonnet 4's performance on coding, computer use, and agent tasks at substantially lower cost and faster speeds.
AI Gateway lets you call the model with a consistent unified API and just a single string update, track usage and cost, and configure performance optimizations, retries, and failover for higher than provider-average uptime.
To use it with the AI SDK v5, set the model to anthropic/claude-haiku-4.5:
Includes built-in observability, Bring Your Own Key support, and intelligent provider routing with automatic retries.
To deliver high performance and reliability to Claude Haiku 4.5, AI Gateway leverages multiple model providers under the hood, including Anthropic, Bedrock and Vertex AI.
Learn more about AI Gateway, view the AI Gateway model leaderboard or try it in our model playground.
Vercel now builds multiple commits to the same branch at the same time when On-Demand Concurrent Builds is enabled. Previously, a new commit would wait for the previous build on that branch to finish before starting. This update eliminates that queue, allowing commits to start building as soon as they arrive.
Visit the On-demand concurrent builds documentation to learn more.
Teams using Observability Plus can now receive alerts when anomalies are detected in their applications to help quickly identify, investigate and resolve unexpected behavior.
Alerts help monitor your app in real-time by surfacing unexpected changes in usage or error patterns:
Usage anomalies: unusual patterns in your application metrics, such as edge requests or function duration.
Error anomalies: abnormal error patterns, such as sudden spikes in 5XX responses on a specific route
View alerts directly in your dashboard, or subscribe via email, Slack, or webhooks to get notified wherever your team works.
Alerts are available public beta for Pro and Enterprise customers with Observability Plus.
Try it out or learn more about Alerts.
Flask, one of the most popular Python web application frameworks, can now be deployed instantly on Vercel with no configuration changes needed.
Vercel's framework-defined infrastructure now recognizes and deeply understands Flask applications. This update removes the need for redirects in vercel.json or using the /api folder.
Backends on Vercel use Fluid compute with Active CPU pricing by default. This means your Flask app will automatically scale up and down based on traffic, and you only pay for time where your code is actively using CPU.
Deploy Flask on Vercel or visit the Flask on Vercel documentation.
Vercel’s Role-Based Access Control (RBAC) system now supports multiple roles per user and introduces extended permissions for finer-grained access control across Enterprise teams.
What’s new:
Multi-role support: Assign multiple roles to a single user within Enterprise teams.
Security role: A new team role dedicated to managing security and compliance settings.
Extended permissions: Add granular capabilities that layer on top of team and project roles for precise control.
Access groups integration: Access Groups now support team roles and extended permissions in Directory Sync mappings.
The new extended permissions include:
Create Project: Create new projects.
Full Production Deployment: Deploy, rollback, and promote to production.
Usage Viewer: View usage, prices, and invoices (read-only).
Integration Manager: Install and manage integrations and storage.
Environment Manager: Create and manage project environments.
Environment Variable Manager: Create and manage environment variables.
Extended permissions apply when paired with a compatible team role. Learn more in the Role-Based Access Control documentation.
Independent developer Theo Browne recently published comprehensive benchmarks comparing server-side rendering performance between Fluid compute and Cloudflare Workers. The tests measured 100 iterations across Next.js, React, SvelteKit, and other frameworks.
The results showed that for compute-bound tasks, Fluid compute performed 1.2 to 5 times faster than Cloudflare Workers, with more consistent response times.
You can now build and deploy ChatGPT apps directly on Vercel, with full support for modern web frameworks.
ChatGPT apps let you integrate custom UI components and functionality within ChatGPT, deployed and served by Vercel.
Frameworks like Next.js can now power these experiences using the Model Context Protocol (MCP), running natively inside the OpenAI sandbox rather than in a nested iframe. Check out our Next.js template.
Build your ChatGPT apps with:
Next.js features like server-side rendering (SSR) and React Server Components
Vercel platform capabilities such as preview deployments, instant rollback, and a seamless dev-to-production pipeline
Get started by building and deploying ChatGPT apps on Vercel using Next.js, Apps SDK, and mcp-handler.
You can now block a deployment from being promoted to production until selected GitHub Actions complete successfully.
On Vercel, every deployment starts in a preview environment, this feature ensures that only verified builds that pass tests or other automated checks are released to production.
Deployment Checks are available for all projects connected to GitHub repositories.
Configure them in your project settings or learn more in the docs.
You can now programmatically search, price, buy, renew, and transfer domains with Vercel’s new Domains Registrar API, complementing the new in-product Domains experience.
The API provides endpoints for:
Catalog & pricing: list supported TLDs; get TLD and per-domain pricing.
Availability: check single or bulk availability.
Orders & purchases: buy domains (including bulk) and fetch order status by ID.
Transfers: retrieve auth codes, transfer in, and track transfer status.
Management: renew, toggle auto-renewal, update nameservers, and fetch TLD-specific contact schemas.
Explore the API docs.
Enterprise customers with Observability Plus can now receive anomaly alerts by email or in-app notifications, in addition to existing delivery options: webhooks, Slack, and the dedicated alerts dashboard.
Currently, two types of anomaly alerts are available:
Usage anomalies: Detects unusual spikes in key billable metrics
Error anomalies: Detects sudden increases in 5XX responses on a specific route or path
Anomaly alerts are available in limited beta for Enterprise customers with Observability Plus.
Try it out or learn more about Alerts.
Vercel now uses uv, a fast Python package manager written in Rust, as the default package manager during the installation step for all Python builds.
This change makes builds 30-65% faster and adds support for more dependency formats. In addition to requirements.txt or Pipfile, projects can now declare dependencies with a uv.lock or pyproject.toml file.
Learn more about the Python runtime on Vercel.
You can now invalidate CDN cache contents by tag.
This marks all cached content associated with the tag as stale. The next request serves stale content instantly while revalidation happens in the background, with no latency impact for users.
There are several ways to invalidate content:
In addition to invalidating by tag, you can also dangerously delete by tag if the origin is gone. However, deleting the cache can increase latency while new content is generated or cause downtime if your origin is unresponsive, so use with caution.
Available on all plans. Learn more about cache invalidation.
Pro and Enterprise teams can now use Static IPs to securely connect to external services like databases that require IP allowlisting. Traffic from builds and functions routes through consistent, shared static IPs.
To enable Static IPs, you can access Connectivity > Static IPs from your project or team settings.
Static IPs are offered in addition to Secure Compute, which remains available for teams that need a fully dedicated VPC model. Note, Secure Compute has also moved within the Connectivity settings of your projects and teams.
This is part of our move to bring more enterprise features self-serve.
Read the docs or enable Static IPs here.
You can now configure Fluid compute on a per-deployment basis.
By setting "fluid": true in your vercel.json, Fluid compute will be activated for that specific deployment. You can also enable or disable Fluid regardless of project level settings.
This allows teams to selectively test and adopt Fluid compute without changing the global project settings.
Read more in our documentation.
Today, Vercel announced an important milestone: a Series F funding round valuing our company at $9.3 billion. The $300M investment is co-led by longtime partners at Accel and new investors at GIC, alongside other incredible supporters. We're also launching a ~$300M tender offer for certain early investors, employees, and former employees.
To all the customers, investors, and Vercelians who have been on this journey with us: thank you.
Stripe is now available in beta on the Vercel Marketplace as a new payment provider.
You can now provision a fully functional Stripe claimable sandbox directly from Vercel with no setup required. When ready, link it to a Stripe account and soon promote it to production.
This makes it easy for teams to move from prototype to production for use cases like:
Ecommerce storefronts: Test complete checkout flows before launch.
SaaS billing: Validate subscriptions, usage-based pricing, and invoicing.
Demos and templates: Share preconfigured environments for testing or client demos.
Developer onboarding: Give teams instant access to ready-to-use Stripe sandboxes.
Get started today with this example to build your first online simple store using Vercel and Stripe.
Vercel inspects every request to identify bot traffic. For requests claiming to come from a verified source, Vercel cross-checks against its directory of verified bots and validates them against strict verification criteria.
We've added three new dimensions to the query builder when analyzing Edge Requests to help you understand bot activity to your projects:
Bot name: Identify specific bots
Bot category: Group bots by type
Bot verified: Distinguish between verified, spoofed, and unverifiable bots
Additionally, the Edge Requests dashboard in Observability now displays verification badges next to bot names.
All users can view bot verification badge while Observability Plus subscribers can query this data at no extra cost.
Try it out or learn more about Observability and Observability Plus.
Claude Sonnet 4.5 is now available on Vercel AI Gateway with full support in AI SDK. We’ve been testing the model in v0, across our Next.js build pipelines, and inside our new Coding Agent Platform template. The model shows improvements in design sensibility and code quality, with measurable gains when building and linting Next.js applications.
Claude Sonnet 4.5 builds on Anthropic's strengths in reasoning and coding. When paired with the Vercel AI Cloud, it powers a new class of developer workflows where AI can plan, execute, and ship changes safely inside your repositories.
Vercel Functions using Node.js can now detect when a request is cancelled and stop execution before completion. This is configurable on a per-path basis, and includes actions like navigating away, closing a tab, or hitting stop on an AI chat to terminate compute processing early.
This reduces unnecessary compute, token generation, and sending data the user would never see.
To enable cancellation, add "supportsCancellation": true to your vercel.json configuration. You can apply it to specific paths or all functions:
Once enabled, you can listen for cancellation using Request.signal.aborted or the abort event:
If you’re using the AI SDK, forward the abortSignal to your stream:
Learn more about cancelling Function requests.
When you deploy a Next.js app with Incremental Static Regeneration (ISR), pages get regenerated on-demand after their cache expires. ISR lets you get the performance benefits of static generation while keeping your content fresh.
But there's a problem. When many users request the same ISR route at once and the cache is expired, each request can trigger its own function invocation. This is called a "cache stampede." It wastes compute, overloads your backend, and can cause downtime.
The Vercel CDN now prevents this with request collapsing. When multiple requests hit the same uncached path, only one request per region invokes a function. The rest wait and get the cached response.
Vercel automatically infers cacheability for each request through framework-defined infrastructure, configuring our globally distributed router. No manual configuration needed.
We’ve rebuilt Vercel Domains end to end, making it faster, simpler, and more affordable to find and buy the right domain for your project.
Search without login: Look up domains instantly, even when you’re not signed in.
At-cost pricing: Domains are offered at registrar cost, with savings up to 50% on popular TLDs.
Transparent results: Availability and pricing surface instantly, with no upsells or unnecessary add-ons.
Fastest search on the web: Real-time, streaming results show availability and premium status instantly.
Expanded TLD coverage: Support for more registries so every project can find the right home.
Bulk checkout: Purchase multiple domains in a single streamlined transaction.
This update makes Vercel Domains the fastest way to claim a name and get to production. As part of the overhaul, we’ve partnered with name.com as our upstream registrar, delivering better pricing and reliability.
An upcoming blog will share how we built this speed using structured concurrency, layered caching, Bloom filters, and partitioned batching.
Try it now at vercel.com/domains.
FastAPI, a modern, high-performance, web framework for building APIs with Python, is now supported with zero-configuration.
Vercel's framework-defined infrastructure now recognizes and deeply understands FastAPI applications. This update removes the need for redirects in vercel.json or using the /api folder.
Backends on Vercel use Fluid compute with Active CPU pricing by default. This means your FastAPI app will automatically scale up and down based on traffic, and you only pay for what you use.
Deploy FastAPI on Vercel or visit the FastAPI on Vercel documentation.
The Vercel CDN now prevents cache stampedes through request collapsing on an expired Incremental Static Regeneration (ISR) page into a single function invocation per region. Without collapsing, simultaneous requests each trigger regeneration, wasting compute and overloading backends. With collapsing, one request regenerates the page while others wait and return the cached result.
This improves reliability, reduces backend load, and saves significant compute at scale.
The feature is applied automatically for cacheable routes. Cacheability is inferred from framework metadata, so no configuration is required.
Implementation details are available in the Preventing the stampede: Request collapsing in the Vercel CDN blog post.
Observability Plus now supports querying and visualizing external API requests.
Observability Plus's query builder allows customers to explore their Vercel data and visualize traffic, performance, and other key metrics. You can now author custom queries on request counts or time to first byte (TTFB) for external API calls, such as fetch requests to an AI provider.
TTFB queries include breakdowns by average, min, max, p75, p90, p95, and p99. You can also filter or group results by request hostname to focus on specific APIs.
The query builder is available to Pro and Enterprise teams using Observability Plus.
Learn more about Observability and Observability Plus.
AI platforms, coding tools, and workflow apps can now create projects on Vercel that users can later claim as their own, transferring deployment ownership together with any resources by third-party providers.
How it works:
Instant deployment: Any third-party can use the Vercel API to create a project, deploy an application, and attach a resource store (such as a database).
Claim and transfer: When a user claims the Vercel deployment, the attached resources automatically move with it. Full ownership of the complete deployment is handed off to the user.
This is available today through Prisma, the first Vercel Marketplace provider to support instant deployment. Prisma customers can now spin up a database and a Vercel-hosted app together as a single, bundled stack.
We’re expanding this flow to more Marketplace providers so they can pair their products, such as authentication, observability, and workflow services, with Vercel deployments through one-click claiming.
Check out our Claim Deployments live demo and documentation to learn more.
Your traffic is spiking and you spot suspicious bot activity in your logs. You deploy BotID expecting to find malicious scrapers, but the results show verified Google bots. Normal crawlers doing their job. But then you notice what they're actually searching for on your site. Queries that have nothing to do with your business. What do you do?
This exact scenario recently played out at one of the largest financial institutions in the world. What they discovered was a years-old SEO attack still generating suspicious traffic patterns.
Enterprise customers with Observability Plus can now be alerted when error events deviate from normal behavior, helping teams catch issues earlier.
The system automatically detects and groups abnormal error patterns, such as sudden spikes in 5XX responses on a specific route. Alert detail pages include relevant log lines, making it easier to investigate and resolve the underlying cause.
Error anomaly detection, joining anomaly alerts for unusual app metric usage, is available in limited beta for Enterprise customers with Observability Plus
Try it out or learn more about Alerts.
If you have feedback or questions, drop them in the Vercel Community thread.
You can now filter deployments in the dashboard by author, using username, email, or Git username. Filters persist in the URL, making it easy to share filtered views with your team.
See now in your project's deployments.
Recently, we shipped an optimization to our global routing service that reduced its memory usage by 15%, improved time-to-first-byte (TTFB) from the 75th percentile and above by 10%, and significantly improved routing speeds for websites with many static paths.
A small number of websites, with hundreds of thousands of static paths, were creating a bottleneck that slowed down our entire routing service. By replacing a slow JSON parsing operation with a Bloom filter, we brought path lookup latency down to nearly zero and improved performance for everyone.
Observability Plus will be replacing the legacy Monitoring subscription for authoring custom queries on Vercel data. With Observability Plus, you have access to an expanded data set and more options for visualizing your Vercel data than was possible with legacy Monitoring. Observability Plus also allows you to save queries and visualizations to Notebooks to share insights and collaborate with team members.
Monitoring will be sunset for Pro customers at the end date of their billing cycle in November.
For Pro customers still subscribed to the legacy Monitoring SKU, we recommend subscribing to Observability Plus before their November billing cycle to continue to access custom queries on their Vercel data. Pro customers who have already subscribed to Observability Plus do not need to take any action.
Learn more about authoring custom queries with Observability Plus.
In February 2025, Andrej Karpathy introduced the term vibe coding: a new way of coding with AI, “[where] you fully give in to the vibes, embrace exponentials, and forget that the code even exists.”
Just months later, vibe coding is completely reshaping how developers and non-developers work. Over 90% of U.S. developers use AI coding tools, adoption is accelerating for other roles, and English has become the fastest growing programming language in the world.
We explore this shift in detail in our new State of Vibe Coding. Here are a few of the key takeaways.
Cold starts have long been the Achilles’ heel of traditional serverless. It’s not just the delay itself, but when the delay happens. Cold starts happen when someone new discovers your app, when traffic is just starting to pick up, or during those critical first interactions that shape whether people stick around or convert.
Traditional serverless platforms shut down inactive instances after a few minutes to save costs. But then when traffic returns, users are met with slow load times while new instances spin up. This is where developers would normally have to make a choice. Save money at the expense of unpredictable performance, or pay for always-on servers that increase costs and slow down scalability.
But what if you didn't have to choose? That’s why we built a better way.
Powered by Fluid compute, Vercel delivers zero cold starts for 99.37% of all requests. Fewer than one request in a hundred will ever experience a cold start. If they do happen, they are faster and shorter-lived than on a traditional serverless platform.
Through a combination of platform-level optimizations, we've made cold starts a solved problem in practice. What follows is how that’s possible and why it works at every scale.
Vercel Agent can now conduct code reviews, with validated suggestions that address issues across correctness, security, and performance.
These reviews are fully codebase-aware, looking beyond the diff to any relevant files. Proposed patches are generated and validated in Vercel Sandboxes before they ever reach your PR.
Key features also include:
Optimizations for frameworks like Next.js, React, Nuxt, and Svelte, with support for TypeScript, Python, Go, and more
High-signal, inline comments for human review including diffs, analysis, and reproduction steps for transparency
In-dashboard Observability for metrics like files read, review time, cost, and more
Configuration options to review all, public, or private repositories, and skip draft PRs
Available in public beta for all Pro and Enterprise teams, pricing is fully usage based with a $100 Vercel Agent credit.
Try it for free in the new Agent dashboard, read more in the docs, or provide feedback in Vercel Community.
Model Context Protocol (MCP) is emerging as a standard protocol for federating tool calls between agents. Enterprises are starting to adopt MCP as a type of microservice architecture for teams to reuse each other's tools across different AI applications.
But there are real risks with using MCP tools in production agents. Tool names, descriptions, and argument schemas become part of your agent's prompt and can change unexpectedly without warning. This can lead to security, cost, and quality issues even when the upstream MCP server has not been compromised or is not intentionally malicious.
We built mcp-to-ai-sdk to reduce these issues. It is a CLI that generates static AI SDK tool definitions from any MCP server. Definitions become part of your codebase, so they only change when you explicitly update them.
Rox is building the next-generation revenue operating system. By deploying intelligent AI agents that can research, prospect, and engage on behalf of sellers, Rox helps enterprises manage and grow revenue faster.
From day one, Rox has built their applications on Vercel. With Vercel's infrastructure powering their web applications, Rox ships faster, scales globally, and delivers consistently fast experiences to every customer.
The Shai-Halud supply chain campaign has escalated. What began with the Qix compromise affecting ~18 core npm packages (chalk, debug, ansi-styles, etc.) has since spread:
Over 40 additional packages attacked via the Tinycolor “worm” vector.
The CrowdStrike / crowdstrike-publisher namespace was also compromised, with multiple trojanized releases.
The DuckDB maintainer account (duckdb_admin) published malicious versions matching the same wallet-drainer malware used in the Qix incidents. No Vercel customers were impacted in that DuckDB subset.
We identified a small set of 10 Vercel customer projects whose builds depended (directly or transitively) on the compromised package versions.
Impacted customers have been notified and provided with project-level guidance.
In the DuckDB incident, no Vercel customer build was affected.
Action | Status |
Blocklisted known compromised versions from the Tinycolor, CrowdStrike, Qix, and DuckDB-affected packages | ✅ Completed |
Purged build caches for Vercel projects using those versions | ✅ Completed for impacted projects |
Coordinated safe rebuilds with clean dependencies / pinned safe versions | ✅ In progress / completed for impacted ones |
Raised platform alerting & detection thresholds for new package publishes matching the Shai-Halud indicators | ✅ Elevated monitoring active |
Working closely with npm, open-source maintainers, and ecosystem security partners to track any further spread of Shai-Halud.
Enhancing our supply chain defenses so that
deployments on Vercel remain secure by default
: stricter policies on lifecycle/postinstall scripts, lockfile hygiene, and registry validation.
Tightening internal CI/CD controls and developer tooling to catch suspicious package behavior early.
For teams using pnpm, consider enabling the new minimumReleaseAge setting introduced in pnpm 10.16 to delay dependency updates (e.g., 24 hours). This helps reduce risk from compromised versions that are discovered and removed shortly after publishing.
Audit your dependencies (direct & transitive) to check for packages from these affected namespaces.
Rebuild with pinned safe versions and clean lockfiles (pnpm ci).
Rotate any npm / GitHub / CI/CD tokens that may have been used in environments where compromised dependencies were present.
Inspect GitHub repos for unauthorized workflows or unexpected .github/workflows additions.
Enforce least privilege (especially in automated workflows), and limit lifecycle script permissions.
September 8, 2025
— Qix / Tinycolor / core package compromise discovered.
September 9, 2025
— DuckDB issue identified.
September 15-16, 2025
— CrowdStrike / Tinycolor “worm” style propagation detected; Vercel detection expanded.
September 16, 2025
— Customer notifications, cache purges, safe rebuilds underway.
The build cache stores files from previous builds to speed up future ones. We've improved its performance by downloading parts of the cache in parallel using a worker pool.
This decreased the build initialization time by 30% on average, reducing build times by up to 7 seconds for all plans.
This is enabled automatically for all new builds and adds to the build initialization improvements previously launched.

Founded in 1877, Helly Hansen is a global leader in technical apparel, but its digital experience wasn't living up to its legacy. Operating across 38 global markets with multiple brands (including HellyHansen.com, HHWorkwear.com, and Musto.com), the company was being held back by an outdated tech stack that slowed site speeds and frustrated customers.
Through an incremental migration to Next.js and Vercel, Helly Hansen improved Core Web Vitals from red to green, increased developer agility, and delivered a record-breaking Black Friday Cyber Monday, building a foundation for future innovation.
Vercel Log Drains are now Vercel Drains.
Why? They’re not just for logs anymore, as you can now also export OpenTelemetry traces, Web Analytics events, and Speed Insights metrics.
Drains give you a single way to stream observability data out of Vercel and into the systems your team already rely on.
Starting October 15, 2025, Vercel will update the default deployment retention policy for all projects currently using the legacy “unlimited” setting:
Canceled Deployments - 30 days, with a maximum of 1 year.
Errored Deployments - 3 months, with a maximum of 1 year.
Pre-Production Deployments - 6 months, with a maximum of 3 years.
Production Deployments - 1 year, with a maximum of 3 years.
Projects with a custom deployment retention setting will not be affected. Additionally, before October 15, the "unlimited" option will become unavailable when modifying retention policies.
Team owners can configure a default retention policy to be applied to any new projects created under the team on Teams > Security & Privacy > Deployment Retention Policy. This policy can also be easily applied to all existing projects.
Note that your 10 most recent production deployments and any currently aliased deployment will never be deleted, regardless of age.
Learn more about Deployment Retention.
AI agents are improving at handling complex tasks, but a recurring limitation emerges when they need to access paid external services. The current model requires pre-registering with every API, managing keys, and maintaining separate billing relationships. This workflow breaks down if an agent needs to autonomously discover and interact with new services.
x402 is an open protocol that addresses this by adding payment directly into HTTP requests. It uses the 402 Payment Required status code to let any API endpoint request payment without prior account setup.
We built x402-mcp to integrate x402 payments with Model Context Protocol (MCP) servers and the Vercel AI SDK.
You can now access Qwen3 Next, two ultra-efficient models from QwenLM, designed to activate only 3B parameters, using Vercel's AI Gateway with no other provider accounts required.
AI Gateway lets you call the model with a consistent unified API and just a single string update, track usage and cost, and configure performance optimizations, retries, and failover for higher than provider-average uptime.
To use it with the AI SDK v5, start by installing the package:
Then set the model to alibaba/qwen3-next-80b-a3b-thinking:

This new max duration unlocks workloads that require longer runtimes, such as large-scale data processing, end-to-end testing pipelines, and long-lived agentic workflows.
Get started with Sandbox now and learn more in the docs.
When the MCP standard first launched, many teams rushed to ship something. Many servers ended up as thin wrappers around existing APIs with minimal changes. A quick way to say "we support MCP".
At the time, this made sense. MCP was new, teams wanted to get something out quickly, and the obvious approach was mirroring existing API structures. Why reinvent when you could repackage?
But the problem with this approach is LLMs don’t work like developers. They don’t reuse past code or keep long term state. Each conversation starts fresh. LLMs have to rediscover which tools exist, how to use them, and in what order. With low level API wrappers, this leads to repeated orchestration, inconsistent behavior, and wasted effort as LLMs repeatedly solve the same puzzles.
MCP works best when tools handle complete user intentions rather than exposing individual API operations. One tool that deploys a project end-to-end works better than four tools that each handle a piece of the deployment pipeline.
We’re updating Vercel’s Pro plan to better align with how modern teams collaborate, how applications consume infrastructure, and how workloads are evolving with AI. Concretely, we’re making the following changes:
Pro teams can now enter into a Business Associate Agreement (BAA) to support HIPAA-compliant workloads on Vercel. The BAA is available self-serve through the dashboard with no Enterprise contract required.
Vercel supports HIPAA compliance as a business associate by implementing technical and organizational safeguards, conducting annual audits, and offering breach notification in line with HIPAA requirements. Compliance is a shared responsibility between you and Vercel. Teams are responsible for configuring security features, managing access, and validating third-party services.
This update makes it easier for healthcare-focused applications to meet regulatory obligations without upgrading to Enterprise.
Read more about other updates to Pro and switch to the new Pro pricing.
Teams on the new Pro pricing model will now have on-demand concurrent builds enabled by default. This ensures builds across projects start immediately without waiting in a queue, except when multiple builds target the same Git branch.
You can manage this setting at any time using the new bulk enable feature, even if your team is not yet on the new Pro pricing model.
Learn more in the documentation read more about the updates to Pro, and switch to the new Pro pricing.
Spend Management is now enabled for new Pro teams, and will be enabled by default for existing teams when they switch to the new pricing model.
All Pro teams will have a budget set by default based on any previous usage, if any, and any teams with existing budgets will be unaffected. This can be changed at any time in spend management settings.
Email alerts will be sent when nearing the spend threshold based on your on-demand spend. This can be changed at any time here.
This new default ensures you receive proactive cost signals to manage your spend. Your deployments will continue without interruption unless a hard limit is manually configured.
Read more about the updates to Pro and switch to the new Pro pricing.
Pro teams can now add unlimited Viewer seats at no additional charge so team members can collaborate more flexibly and cost-efficiently.
Viewers can access project dashboards, deployments, analytics, and more, but can’t see sensitive data, deploy, or change production settings. This is ideal for any team members looking to collaborate via access to the dashboard and preview deployments.
Previously, all seats on Pro were paid. Moving forward, you can add two main types of seats:
Developer seats (Owner, Member): Team members that deploy, debug, and configure. These seats remain $20.
Viewer seats: Team members that do not deploy. These seats are free.
Viewers can easily request an upgrade from team owners directly in the dashboard.
Read more about the updates to Pro and switch to the new Pro pricing.
The Pro plan now includes $20 in monthly usage credit instead of fixed allocations across metrics like data transfer, compute, caching, and more. This plan update replaces static usage buckets with a more flexible system that adapts to your workload.
In addition to the above, the new Pro pricing model includes:

On September 9, 2025, the campaign extended to DuckDB-related packages after the duckdb_admin account was breached. These releases contained the same wallet-drainer malware, confirming this was part of a coordinated effort targeting prominent npm maintainers.
While Vercel customers were not impacted by the DuckDB incident, we continue to track activity across the npm ecosystem with our partners to ensure deployments on Vercel remain secure by default.
Average npm install time for v0 builds dropped from 5s to 1.5s by optimizing how dependencies are resolved and cached during build execution.
This is in addition to a recent improvement to time-to-start for v0 builds, with more improvements in progress to further reduce installation and overall build time.
Deploy today on v0.app.

Vercel Functions running on Node.js and Python runtimes now support graceful shutdown, giving you up to 500 milliseconds to run cleanup tasks before termination.
When a function is terminated, such as during scale-down, the runtime receives a SIGTERM signal. You can now use this signal to run cleanup tasks like closing database connections or flushing external logs.
Learn more about the SIGTERM signal.
Users can export OpenTelemetry traces, Web Analytics events, and Speed Insights data points from Vercel to any third-party tool. We’ve expanded our Log Drains infrastructure, enabling users to stream more raw data out of Vercel and into external systems.
With Vercel Drains, users can configure custom HTTP endpoints to receive data in multiple encodings — JSON, NDJSON, or Protobuf.
Pro and Enterprise teams can export data to external systems at the same $0.50 per GB rate.
Try it out or learn more about Vercel Drains.
Express, a fast, unopinionated, minimalist web framework for Node.js, is now supported with zero-configuration.
Vercel's framework-defined infrastructure now recognizes and deeply understands Express applications. This update removes the need for redirects in vercel.json or using the /api folder.
Deploy Express on Vercel or visit the Express on Vercel documentation.
Recently we partnered with the Biome team to strengthen their noFloatingPromises lint rule to catch more subtle edge cases. This rule prevents unhandled Promises, which can cause silent errors and unpredictable behavior. Once Biome had an early version ready, they asked if we could help stress test it with some test cases.
At Vercel, we know good tests require creativity just as much as attention to detail. To ensure strong coverage, we wanted to stretch the rule to its limits and so we thought it would be fun to turn this into a friendly internal competition. Who could come up with the trickiest examples that would still break the updated lint rule?
Part of the fun was learning together, but before we dive into the snippets, let’s revisit what makes a Promise “float”.
You can now access Kimi K2 0905, a new model from Moonshot AI focused on agentic coding with a 256K context window, using Vercel AI Gateway with no other provider accounts required.

At Vercel, our relationship with open source is foundational. We do not build open source software to make money. Rather, we’re building an enduring business that enables us to continue developing great open source software. We believe in improving the default quality of software for everyone, everywhere, whether they are Vercel customers or not. A rising tide lifts all boats.
A vulnerability affecting Next.js Middleware has been addressed. It impacted versions prior to v14.2.32 and v15.4.7, and involved a Server-Side Request Forgery (SSRF) risk introduced by misconfigured usage of the NextResponse.next() function within middleware. Applications that reflected a user's request headers in this function, rather than passing them through the request object, could unintentionally allow the server to issue requests to attacker-controlled destinations.
A patch applied on August 25th, 2025 eliminated exposure for Vercel customers running the affected versions.
In affected configurations, an attacker could:
Influence the destination of internal requests triggered by middleware routing logic
Perform SSRF against internal infrastructure if user-controlled headers (e.g.,
Location) were forwarded or interpreted without validation
Potentially access sensitive internal resources or services unintentionally exposed via internal redirect behavior
This issue is exploitable in self-hosted deployments where developers use custom middleware logic and do not adhere to documented usage of NextResponse.next({ request }). It is not exploitable on Vercel infrastructure, which isolates and protects internal request behavior.
The issue was resolved by updating the internal middleware logic to prevent unsafe fallback behavior when request is omitted from the next() call. This ensures the origin server behavior cannot be unintentionally altered by user-supplied headers or misrouted requests.
Fix available in:
Next.js v14.2.32
Next.js v15.4.7
For users who cannot upgrade immediately:
Ensure middleware follows official guidance: Use NextResponse.next({ request })to explicitly pass the request object
Avoid forwarding user-controlled headers to downstream systems without validation
Ensure headers that should never be sent from client to server are not reflected back to the client via NextResponse.next, such as Location.
Thanks to Dominik Prodinger at RootSys, and Nicolas Lamoureux and the Latacora team for their responsible disclosure.
A vulnerability affecting Next.js Image Optimization has been addressed. It impacted versions prior to v15.4.5 and v14.2.31, and involved a scenario where attacker-controlled external image servers could serve crafted responses that result in arbitrary file downloads with attacker-defined filenames and content.
Your Vercel deployments are safe by default. A patch applied on July 29th, 2025 eliminated exposure for all Vercel-hosted customers. Self-hosted deployments should upgrade to v15.4.5 or v14.2.31 to remediate the issue.
Under certain configurations (images.domains or permissive images.remotePatterns), a malicious actor could:
Trigger the download of a file from a Next.js app with attacker-controlled content and filename
Exploit this behavior for phishing, drive-by downloads, or social engineering scenarios
This issue requires that:
The target app has external image domains or patterns configured
The remote server is attacker-controlled or attacker-influenced
A user is tricked into clicking a crafted URL
The issue was resolved by updating the image optimizer logic to avoid falling back to the upstream’s Content-Type header when magic number detection fails. This ensures that responses are only cached when confidently identified as image content and do not mistakenly reuse cache keys for user-specific responses.
The fix was included in:
Next.js v15.4.5
Next.js v14.2.31
Thanks to kristianmagas for the responsible disclosure.
A vulnerability affecting Next.js Image Optimization has been addressed. It impacted versions prior to v15.4.5 and v14.2.31, and involved a cache poisoning issue that caused sensitive image responses from API routes to be cached and subsequently served to unauthorized users.
Vercel deployments were never impacted by this vulnerability.
When API routes are used to return image content that varies based on headers (e.g., Cookie, Authorization), and those images are passed through Next.js Image Optimization, the optimized image may be cached without including those request headers as part of the cache key. This can lead to:
Unauthorized disclosure of user-specific or protected image content
Cross-user leakage of conditional content via CDN or internal cache
This issue arises without user interaction and requires no elevated privileges, only a prior authorized request to populate the cache.
The issue was resolved by ensuring request headers aren’t forwarded to the request that is proxied to the image endpoint. This ensures that the image endpoint cannot be used to serve images that require authorization data and thus cannot be cached.
Fix available in:
Next.js v15.4.5
Next.js v14.2.31
Thanks to reddounsf for the responsible disclosure.
Many engineering teams have disaster recovery plans. But unless those plans are regularly exercised on production workloads, they don’t mean much. Real resilience comes from verifying that systems remain stable under pressure. Not just in theory, but in practice.
On July 24, 2025, we successfully performed a full production failover of our core control-plane database from Azure West US to East US 2 with zero customer impact.
This was a test across all control-plane traffic: every API request, every background job, every deployment and build operation. Preview and development traffic routing was affected, though our production CDN traffic, served by a separate globally-replicated DynamoDB architecture, remained completely isolated and unaffected across our 19 regions.
This operation was a deliberate, high-stakes exercise. We wanted to ensure that if the primary region became unavailable, our systems could continue functioning with minimal disruption. The result: a successful failover with zero customer downtime, no degraded performance in production, and no postmortem needed.
Threat actors published modified versions of the Nx package and some of its supporting libraries to the npm registry with the goal of exfiltrating developer and service credentials.
Builds on Vercel are safe from this vulnerability by default. Visit the GitHub advisory to check if your local or other CI environments are impacted.
A malicious version of the Nx package and some Nx ecosystem libraries were published to the npm registry using a stolen npm token, starting at 6:32 PM EDT on August 26, 2025. The compromised packages were removed from the npm registry by the Nx team, ending at 10:44 PM EDT on the same day.
The affected packages contained a postinstall script that scanned the user's file system using an LLM to exfiltrate secrets and credentials when installing an affected package. Exfiltrated secrets were posted as an encoded string into a GitHub repo that the script would create in the victim's GitHub account. For more information, visit the advisory on GitHub from the Nx team.
By default, Vercel customers are not impacted, and can only be affected by the compromised Nx packages if they took specific steps leveraging the build container's flexibility.
Four conditions are required for the postinstall script to exfiltrate data from a Vercel build:
The script uses the GitHub CLI (gh) to acquire a GitHub token. The GitHub CLI is not installed in Vercel's build container by default. For the GitHub CLI to be present in your build, it must be installed as part of your user-defined build process.
The script requires a GitHub authentication token to be present on the machine invoking the GitHub CLI. The Vercel build container does not contain customer GitHub tokens by default. For the GitHub token to be present in your build, it must be added to the build container as part of your user-defined build process.
The script depends on the machine having at least one of the Claude Code (claude), Gemini (gemini), or Q (q) CLIs installed. The Vercel build container does not have any of these installed by default. For any of these CLIs to be present in your build, they must be installed as part of your user-defined build process.
A build must have installed a compromised version of Nx or Nx ecosystem packages.
We did not identify any builds on Vercel meeting this pattern. We encourage you to evaluate other environments, local and cloud, that may have been vulnerable to this attack.
New builds will not be able to download the affected packages. The Nx team has removed affected packages from npm, and we have purged the build caches for any projects that contained affected packages in their dependencies during a build.
Additionally, we've notified a small number of users who installed one or more of the malicious packages during a build. Vercel team owners should check for an email titled "s1ngularity: supply chain attack in Nx packages" from security@vercel.com.
Enterprise customers can now receive alerts when anomalies are detected in their applications, in order to quickly identify and mitigate issues.

We've published @vercel/slack-bolt, our official adapter for deploying Slack's Bolt for JavaScript to Vercel's AI Cloud.
Bolt provides a type-safe library for responding to Slack webhook events. However, Slack's API requires a response within three seconds or users are faced with timeouts. This has made it hard to build Slack agents on traditional serverless platforms.
Our adapter uses Fluid compute’s streaming and waitUntil to acknowledge responses within Slack’s deadline while your agent continues working in the background.
This adapter works with any function or framework using the Web API Request object such as Hono, Nitro or Next.js.
Get started with our Slack Agent Template today or visit the library on npm.
SAML-based Single Sign-On (SAML SSO) is now available as an add-on to all Pro teams and can be configured directly in the dashboard. This includes support for major identity providers like Okta, Azure AD, and Google Workspace.

Read more about using AI tools with Vercel MCP.
Prototyping with AI should feel fast, collaborative, and on brand. Most AI tools have cracked the "fast" and "collaborative" parts, but can struggle with feeling "on-brand". This disconnect usually stems from a lack of context.
For v0 to produce output that looks and feels right, it needs to understand your components. That includes how things should look, how they should behave, how they work together, and all of the other nuances.
Most design systems aren’t built to support that kind of reasoning.
However, a design system built for AI enables you to generate brand-aware prototypes that look and feel production ready. Let's look at why giving v0 this context creates on-brand prototypes and how you can get started.
Vercel now supports xmcp, a framework for building and shipping MCP servers with TypeScript, with zero-configuration.
xmcp uses file-based routing to create tools for your MCP server.
Once you've created a file for your tool, you can use a default export in a way that feels familiar to many other file-based routing frameworks. Below, we create a "greeting" tool.
Learn more about deploying xmcp to Vercel in the documentation.
Building an AI app can now take just minutes. With developer tools like the AI SDK, teams can build both AI frontends and backends that accept prompts and context, reason with an LLM, call actions, and stream back results.
But going to production requires reliability and stability at scale. Teams that connect directly to a single LLM provider for inference create a fragile dependency: if that provider goes down or hits rate limits, so does the app. As AI workloads become mission-critical, the focus shifts from integration to reliability and consistent model access. Fortunately, there's a better way to run.
AI Gateway, now generally available, ensures availability when a provider fails, avoiding low rate limits and providing consistent reliability for AI workloads. It's the same system that has powered v0.app for millions of users, now battle-tested, stable, and ready for production for our customers.
AI Gateway is now generally available, providing a single unified API to access hundreds of AI models with transparent pricing and built-in observability.
With sub-20ms latency routing across multiple inference providers, AI Gateway delivers:
Transparent pricing with no markup on tokens (including Bring Your Own Keys)
Automatic failover for higher availability
High rate limits
Detailed cost and usage analytics
You can use AI Gateway with the AI SDK or through the OpenAI-compatible endpoint. With the AI SDK, it’s just a simple model string switch.

With their focus on delivering expressive, scalable digital experiences, the team uses v0 to shorten the path from idea to working software.
How do you tell an AI agent what it needs to do when it hits a protected page? Most systems rely on external documentation or pre-configured knowledge, but there's a simpler approach.
What if the instructions were right there in the HTML response?
llms.txt is an emerging standard for making content such as docs available for direct consumption by AIs. We’re proposing a convention to include such content directly in HTML responses as <script type="text/llms.txt">.
Two new tools are now available in Vercel’s MCP server:
get_access_to_vercel_url Generates a shareable URL that allows agent tools such as web fetch or Playwright to access deployments protected by Vercel Authentication. The URL is temporary and grants access without requiring login credentials.
web_fetch_vercel_url Allows agents to directly fetch content from deployments protected by Vercel Authentication, even if a normal fetch would return 401 Unauthorized or 403 Forbidden.
Get started with the Vercel MCP server.
Vercel Functions running on the Node.js runtime now support the fetch web handlers, improving interoperability across JavaScript runtimes and frameworks.
You can still export individual HTTP methods, if preferred.
Learn more about fetch web handlers in the docs.
Autonomous coding agents are not the future. They are already here. Agents can now design, build, test, and deploy an entire full-stack feature from front end to back end without a human touching the keyboard.
The reality is that while this technology has advanced quickly, Generally Accepted Accounting Principles (GAAP) have not traditionally focused on the cost of tools used in development. Under current U.S. GAAP, you can capitalize certain third-party software costs if they are a direct cost of creating software during the application development stage. Historically, though, developer tools were treated as overhead because their cost could not be directly tied to capitalizable work. Under GAAP, work that meets the criteria should be capitalized. When agents perform that work, they should be treated no differently than salaried engineers.
Vercel now directly integrates with SvelteKit's new server-side OpenTelemetry spans.
To get started, activate experimental tracing in SvelteKit:
And create the tracing instrumentation file with the Vercel OpenTelemetry collector:
Traces generated during tracing sessions will now include the built-in SvelteKit spans. You can also configure other collectors. See the SvelteKit observability docs for more information.
Pro and Enterprise teams can now run up to 2,000 Vercel Sandboxes concurrently (up from 150), with each now able to expose up to 4 ports for external access.
This enables larger traffic spikes for workloads like untrusted code execution, batch jobs, and automated testing, as well as more complex applications with multiple services or protocols running side-by-side.
If you need a higher amount of concurrent sandboxes, you can contact our sales team to explore higher limits for your projects.

Vercel BotID Deep Analysis now uses an updated detection model that expands fingerprinting coverage for bespoke headless browsers and simulated device hardware.
BotID is an invisible CAPTCHA that classifies sophisticated bots without interrupting real users. The new Deep Analysis model enables more accurate identification of stealthy automation frameworks and spoofed hardware profiles in real time.
These updates take effect immediately for BotID Deep Analysis users with no action required, but we recommend upgrading to the latest botid@1.5.2.
Get started with BotID today.
AI bot traffic is growing across the web. We track this in real-time, and the data reveals three types of AI-driven crawlers that often work independently but together create a discovery flywheel that many teams disrupt without realizing it.
Not all bots are harmful. Crawlers have powered search engines for decades, and we've spent just as long optimizing for them. Now, large language models (LLMs) need training data, and the AI tools built on them need timely, relevant updates. This is the next wave of discoverability and getting it right from the start can determine whether AI becomes a growth channel or a missed opportunity.
Blocking AI crawlers today is like blocking search engines in the early days and then wondering why organic traffic vanishes. As users shift from Googling for web pages to prompting for direct answers and cited sources, the advantage will go to sites that understand each type of bot and choose where access creates value.
There is a long-standing myth that serverless compute inherently requires more connections to traditional databases. The real issue is not the number of connections needed during normal operation, but that some serverless platforms can leak connections when functions are suspended.
In this post, we show why this belief is incorrect, explain the actual cause of the problem, and provide a straightforward, simple-to-use solution.
Coxwave helps enterprises build GenAI products that work at scale. With their consulting arm, AX, and their analytics platform, Align, they support some of the world’s most technically sophisticated companies, including Anthropic, Meta, Microsoft, and PwC.
Since the company’s founding in 2021, speed has been a defining trait. But speed doesn’t just mean fast models. For Coxwave, it means fast iteration, fast validation, and fast value delivery.
To meet that bar, Coxwave reimagined their web app strategy with Next.js and Vercel.
You can now access Vercel's Runtime Cache via API.

We collaborated with industry partners to advance the IETF proposal for Web Bot Auth and Vercel's bot verification system supports the new protocol. Now, Bot Protection can use HTTP Message Signatures to verify traffic automation from dynamic and distributed sources.
Vercel maintains a comprehensive and actively curated directory of known bots that are verified by IP, reverse DNS, and now Web Bot Auth, which verifies bots via public-key cryptography in signed headers. This ensures that legitimate automation, like SEO crawlers, performance monitoring tools, and platform-integrated AI bots, can reliably access your site, while spoofed bots are blocked.
Web Bot Auth's asymmetric signature proves the authenticity of the traffic regardless of its network origin, making it ideal for bots running in dynamic or serverless environments.
Verified Bots using Web Bot Auth include signed headers to authenticate each request, allowing them to be recognized and allowed through Bot Protection and Challenge Mode. For example, ChatGPT operator signs its requests using Web Bot Auth, so is now allowed.
Learn more about Bot Management.
Starting in botid@1.5.0, BotID’s Deep Analysis mode provides authenticated information for verified bots based on Vercel's directory of known and verified bots. This allows developers to detect verified bots in real time and make programmatic decisions based on bot identity.
This allows you to securely allow known bots that are good for your business (such as agentic bots that purchase on behalf of users) while blocking other bots and sophisticated abuse.
BotID is an invisible CAPTCHA that classifies sophisticated bots without interrupting real users. With this update, developers using Deep Analysis now get additional context about the bot itself, such as source IP range, reverse DNS, and user-agent validation, helping teams fine-tune how bots are handled before taking action.
Get started with BotID and check out the documentation for verified bots in BotID.

Vibe coding has changed how software gets built. Tools like v0 make it possible to turn ideas into working prototypes in seconds. Anthropic's CEO predicts 90% of code will be AI-generated in 3-6 months. Adoption is accelerating fast, and for many builders, we're already there.
But here's the uncomfortable truth: The faster you build, the more risk you create
Last week, a viral app leaked 72k selfies and government IDs. This wasn’t a hack or advanced malware. It was caused by default settings, misused variables, and the absence of guardrails. A misconfigured Firebase bucket that was mistakenly left public for anyone to access. The app was built quickly, shipped without security review, and went viral.

Deployment Protection safeguards preview and production URLs so that users can't access the domains that you don't want them to. Starting today, the Standard Deployment Protection option has been updated for new projects to protect all automatically generated domains, including the production branch git domain (for example project-git-main.vercel.app). Existing projects can update to this new behavior in the Project settings page in the Vercel dashboard.
For over a decade, Vercel has helped teams develop, preview, and ship everything from static sites to full-stack apps. That mission shaped the Frontend Cloud, now relied on by millions of developers and powering some of the largest sites and apps in the world.
Now, AI is changing what and how we build. Interfaces are becoming conversations and workflows are becoming autonomous.
We've seen this firsthand while building v0 and working with AI teams like Browserbase and Decagon. The pattern is clear: developers need expanded tools, new infrastructure primitives, and even more protections for their intelligent, agent-powered applications.
At Vercel Ship, we introduced the AI Cloud: a unified platform that lets teams build AI features and apps with the right tools to stay flexible, move fast, and be secure, all while focusing on their products, not infrastructure.

With sudo on Sandbox it's easier to run untrusted code in isolated environments with the right permissions, with no workarounds required.
Learn more about Vercel Sandbox and sudo in the documentation.
Vercel now automatically correlates logs with distributed traces for customers using OpenTelemetry to instrument their applications.
Traces are a way to collect data about the performance and behavior of your application and help identify the cause of performance issues, errors, and other problems. OpenTelemetry (OTel) is an open source project that allows you to instrument your application to collect traces.
When a request is traced using OTel, Vercel will enrich the relevant logs with trace and span identifiers. This allows you to correlate your individual logs to a trace or span.
This feature is available to customers using log drains through our integrations with Datadog and Dash0. No action is required and log to trace correlation will happen automatically going forward for customers using OTel with any of these integrations.
Learn more about correlating logs to traces using log drains.
A cache poisoning vulnerability affecting Next.js App Router >=15.3.0 < 15.3.3 / Vercel CLI 41.4.1–42.2.0 has been resolved. The issue allowed page requests for HTML content to return a React Server Component (RSC) payload instead under certain conditions. When deployed to Vercel, this would only impact the browser cache, and would not lead to the CDN being poisoned. When self-hosted and deployed externally, this could lead to cache poisoning if the CDN does not properly distinguish between RSC / HTML in the cache keys.
Under specific conditions involving App Router, middleware redirects, and omitted Vary headers, applications may:
Serve RSC payloads in place of HTML
Cache these responses at the browser or CDN layer
Display broken or incorrect client content
This issue occurs in environments where middleware rewrites or redirects result in improper cache key separation, because the cache-busting parameter added by the framework is stripped by the user’s redirect.
The issue was resolved in Next.js 15.3.3 by:
Ensuring the Vary header is correctly set to distinguish between different content types
Customers hosting on Vercel with deployments that used the impacted CLI versions must redeploy their applications to receive the fix.
Manually add the Vary header on RSC responses to differentiate between RSC and HTML payloads. Specifically, Vary: RSC, Next-Router-State-Tree, Next-Router-Prefetch.
Apply a unique cache-busting search parameter to the middleware redirect destination
Thanks to internal incident response teams and affected Vercel customers for timely reports and debugging assistance.
A vulnerability affecting Next.js has been addressed. It impacted versions >=15.1.0 <15.1.8 and involved a cache poisoning bug leading to a Denial of Service (DoS) condition.
This issue does not impact customers hosted on Vercel.
Under certain conditions, this issue may allow a HTTP 204 response to be cached for static pages, leading to the 204 response being served to all users attempting to access the page.
This issue required the below conditions to be exploitable:
Using an affected version of Next.js, and;
A route using cache revalidation with ISR (next start or standalone mode); and
A route using SSR, with a CDN configured to cache 204 responses.
The issue was resolved by removing the problematic code path that would have caused the 204 response to be set. Additionally, we removed the race condition that could have led to this cache poisoning by no longer relying on a shared response object to populate the Next.js response cache.
Thanks to Allam Rachid (zhero) and Allam Yasser (inzo_) for responsible disclosure.
Pro teams can now access a new usage dashboard (recently introduced to Enterprise customers) with improved filtering, detailed breakdowns, and export options to better understand usage and costs by product and project.

Deploy Nitro on Vercel or visit Nitro's Vercel documentation.
My first week at Vercel coincided with something extraordinary: Vercel Ship 2025.
Vercel Ship 2025 showcased better building blocks for the future of app development. AI has made this more important than ever. Over 1,200 people gathered in NYC for our third annual event, to hear the latest updates in AI, compute, security, and more.
You can now subscribe to webhook events for deeper visibility into domain operations on Vercel.
New event categories include:
Domain transfers: Track key stages in inbound domain transfers.
Domain renewals: Monitor renewal attempts and auto-renew status changes, ideal for catching failures before they impact availability.
Domain certificates: Get notified when certificates are issued, renewed, or removed, helping you maintain valid HTTPS coverage across environments.
DNS changes: Receive alerts when DNS records are created, updated, or deleted.
Project Domain Management: Detect domain lifecycle changes across projects, including creation, updates, verification status, and reassignment.
These events are especially valuable for multi-tenant platforms that dynamically assign domains per user or customer. They also help teams build monitoring and alerting into critical domain and certificate operations.
For details on how to subscribe, visit the webhook documentation.
Modern sophisticated bots don’t look like bots. They execute JavaScript, solve CAPTCHAs, and navigate interfaces like real users. Tools like Playwright and Puppeteer can script human-like behavior from page load to form submission.
Traditional defenses like checking headers or rate limits aren't enough. Bots that blend in by design are hard to detect and expensive to ignore.
Enter BotID: A new layer of protection on Vercel.
Think of it as an invisible CAPTCHA to stop browser automation before it reaches your backend. It’s built to protect critical routes where automated abuse has real cost such as checkouts, logins, signups, APIs, or actions that trigger expensive backend operations like LLM-powered endpoints.
Fluid compute exists for a new class of workloads. I/O bound backends like AI inference, agents, MCP servers, and anything that needs to scale instantly, but often remains idle between operations. These workloads do not follow traditional, quick request-response patterns. They’re long-running, unpredictable, and use cloud resources in new ways.
Fluid quickly became the default compute model on Vercel, helping teams cut costs by up to 85% through optimizations like in-function concurrency.
Today, we’re taking the efficiency and cost savings further with a new pricing model: you pay CPU rates only when your code is actively using CPU.
Vercel Queues is a message queue service built for Vercel applications, in Limited Beta.
Vercel Queues lets you offload work by sending tasks to a queue, where they’ll be processed in the background. This means users don’t have to wait for slow operations to finish during a request, and your app can handle retries and failures more reliably.
Under the hood, Vercel Queues uses an append-only log to store messages and ensures tasks such as AI video processing, sending emails, or updating external services are persisted and never lost.
Key features of Vercel Queues:
Pub/Sub pattern: Topic-based messaging allowing for multiple consumer groups
Streaming support: Handle payloads without loading them entirely into memory

Vercel BotID is an invisible CAPTCHA with no visible challenges or manual bot management required.
BotID is a new protection layer on Vercel designed for public, high-value routes such as checkouts, signups, AI chat interfaces, LLM-powered endpoints, and public APIs that are targets for sophisticated bots mimicking real user behavior.
Unlike IP-based or heuristic systems, BotID:
Silently collects thousands of signals that distinguish human users from bot
Mutates these detections on every page load, evading reverse engineering and sophisticated bypasses
Streams attack data into a global machine learning mesh, collectively strengthening protection for all customers
Powered by Kasada, BotID integrates into your application with a type-safe SDK:
Client-side detection using the <BotIdClient> component
Server-side verification with the checkBotId function
Automatic labeling of logs and telemetry for blocked sessions
BotID traffic is visible in the Firewall dashboard and can be filtered by verdict (pass or fail), user agent, country, IP address, request path, target path, JA4 digest, and host.
Read the announcement or documentation to learn more, or try BotID today.
Vercel Microfrontends is now available in Limited Beta for Enterprise teams, enabling you to deploy and manage multiple frontend applications that appear as one cohesive application to users.
This allows you to split large applications into smaller, independently deployable units that each team can build, test, and deploy using their own tech stack, while Vercel handles integration and routing across the platform.
Faster development for large apps: Smaller units reduce build times and enable teams to move independently
Independent team workflows: Each team manages its own deployment pipeline and framework
Incremental migration: Modernize legacy systems piece by piece without slow, large-scale rewrites
Learn more about Vercel Microfrontends. Reach out to your account representative or contact sales to join the limited beta.
Rolling Releases are now generally available, allowing safe, incremental rollouts of new deployments with built-in monitoring, rollout controls, and no custom routing required.
Each rollout starts at a defined stage and can either progress automatically or be manually promoted to a full release. You can configure rollout stages per project and decide how each stage progresses, with updates propagating globally in under 300ms through our fast propagation pipeline.
Rolling releases also include:
Real-time monitoring: Track and compare error rates and Speed Insights (like Core Web Vitals, Time to First Byte, and more) between versions
Flexible controls: Rollouts can be managed via REST API, CLI, the project dashboard, or the Vercel Terraform provider
Version-labeled logs: Logs and telemetry are labeled by deployment for easier debugging
Pro and Enterprise teams can enable Rolling Releases on one project at no additional cost. Enterprise customers can upgrade to unlimited projects.
Learn more about Rolling Releases or enable it on your project.
The default limits for Vercel Functions using Fluid compute have increased, with longer execution times, more memory, and more CPU.
The default execution time, for all projects on all plans, is now 300 seconds (5 minutes):
Plan | Default | Maximum |
|---|---|---|
Hobby | 300s (previously 60s) | 300s (previously 60s) |
Pro | 300s (previously 90s) | 800s |
Enterprise | 300s (previously 90s) | 800s |
Memory and CPU instance sizes have also been updated:
Standard (default) is now 1 vCPU / 2 GB (previously 1 vCPU / 1.7 GB)
Performance is now 2 vCPU / 4 GB (previously 1.7 vCPU / 3 GB)
These increased instances are enabled by Active CPU pricing, which charges based on actual compute time. Periods of memory-only usage are billed at a significantly lower rate, making longer executions more cost-efficient.
You can view logs to determine if your functions are hitting execution limits and adjust the max duration or upgrade your plan as needed.
Learn more about Vercel Function limits.
Functions using the Edge runtime now run on the unified Vercel Functions infrastructure.
This applies to both before and after the cache:
Edge Middleware is now Vercel Routing Middleware, a new infrastructure primitive that runs full Vercel Functions with Fluid compute before the cache
Edge Functions are now Vercel Functions using the Edge Runtime after the cache
With these changes, all functions including those running the Edge runtime are:
Fluid compute-ready: Runs on Fluid compute for better performance and cost efficiency
Multi-runtime: Supports Node.js and Edge runtimes
Framework-driven: Deployed automatically from supported framework code
Consistent pricing: Uses unified Vercel Functions pricing based on Active CPU time across all compute types
Vercel Routing Middleware is now generally available to all users.
Learn more about Routing Middleware.
Vercel Sandbox is a secure cloud resource powered by Fluid compute. It is designed to run untrusted code, such as code generated by AI agents, in isolated and ephemeral environments.
Sandbox is a standalone SDK that can be executed from any environment, including non-Vercel platforms. Sandbox workloads run in ephemeral, isolated microVMs via the new Sandbox SDK, supporting execution times up to 45 minutes.
Sandbox uses the Fluid compute model and charges based on Fluid’s new Active CPU time, meaning you only pay for compute when actively using CPU. See Sandbox pricing for included allotments and pricing for Hobby and Pro teams.
Now in Beta and available to customers on all plans. Learn more about Vercel Sandbox.
Vercel Functions on Fluid Compute now use Active CPU pricing, which charges for CPU only while it is actively doing work. This eliminates costs during idle time and reduces spend for workloads like LLM inference, long-running AI agents, or any task with idle time.
Active CPU pricing is built on three core metrics:
Active CPU: Time your code is actively executing in an instance. Priced at $0.128 per hour
Provisioned Memory: Memory allocated to the instance, billed at a lower rate. Priced at $0.0106 per GB-Hour
Invocations: One charge per function call
An example of this in action:
A function running Standard machine size at 100% active CPU would now cost ~$0.149 per hour (1 Active CPU hour + 2 GB of provisioned memory). Previously this would have cost $0.31842 per hour (1.7 GB Memory × $0.18).
Active CPU pricing is now enabled by default for all Hobby, Pro, and new Enterprise teams. For existing Enterprise customers, availability depends on your current plan configuration.
This change takes effect after a redeploy.
Learn more about Fluid compute with Active CPU pricing and read the announcement.
AI Gateway gives you a single endpoint to access a wide range of AI models across providers, with better uptime, faster responses, no lock-in.

Users with the Member role can now purge Vercel’s CDN cache manually, either via the project's cache settings dashboard or by running vercel cache purge --type=cdn in CLI version 44.2.0 or later.
By default, the CDN cache is purged automatically with each new deployment. For cases where you want to refresh cached content instantly (without waiting for a new build), you can now manually purge the global CDN cache in milliseconds.
This is especially useful for persistent cache scenarios, like Image Optimization, where paths are cached across deployments. If upstream images have changed, you can now force a refresh instantly.
Learn more in the documentation.
The Vercel CLI (version 43.3.0) now includes Blob commands, allowing you to manage your Vercel Blob stores and files directly from the terminal.
Learn more about the Vercel Blob CLI and Vercel Blob.

Tray.ai is a composable AI integration and automation platform that enterprises use to build smart, secure AI agents at scale.
To modernize their marketing site, they partnered with Roboto Studio to migrate off their legacy solution and outdated version of Next.js. The goal: simplify the architecture, consolidate siloed repos, and bring content and form management into one unified system.
After moving to Vercel, builds went from a full day to just two minutes.
Dubai (dxb1) is now part of Vercel’s delivery network, extending our global CDN's caching and compute to reduce latency for users in the Middle East, Africa, and Central Asia without requiring any changes.
The new Dubai region serves as the first stop for end-users based on proximity and network conditions. It's generally available and serving billions of requests.
Teams can configure Dubai as an execution region for Vercel Functions, which supports Fluid compute to increase resource and cost efficiency, minimize cold starts, and scale dynamically with demand.
Learn more about Vercel Regions and Dubai's regional pricing.
The Model Context Protocol (MCP) standardizes how to build integrations for AI models. We built the MCP adapter to help developers create their own MCP servers using popular frameworks such as Next.js, Nuxt, and SvelteKit. Production apps like Zapier, Composio, Vapi, and Solana use the MCP adapter to deploy their own MCP servers on Vercel, and they've seen substantial growth in the past month.
MCP has been adopted by popular clients like Cursor, Claude, and Windsurf. These now support connecting to MCP servers and calling tools. Companies create their own MCP servers to make their tools available in the ecosystem.
The growing adoption of MCP shows its importance, but scaling MCP servers reveals limitations in the original design. Let's look at how the MCP specification has evolved, and how the MCP adapter can help.
We've improved the team overview in the Vercel dashboard:
Activity is now sorted by your activity only
Projects can be filtered by git repository
Usage for the team is now shown as a card on the overview directly
To learn more about the Vercel dashboard, visit the documentation.
Fluid compute now gracefully handles uncaught exceptions and unhandled rejections in Node.js by logging the error, allowing inflight requests to complete, and then exiting the process.
This prevents concurrent requests running on same fluid instance from being inadvertently terminated in case of unhandled errors, providing the isolation of traditional serverless invocations.
Enable Fluid for your existing projects, and learn more in our blog and documentation.
Our two conferences (Vercel Ship and Next.js Conf) are our chance to show what we've been building, how we're thinking, and cast a vision of where we're going next.
It's also a chance to push ourselves to create an experience that builds excitement and reflects the quality we strive for in our products. For Vercel Ship 2025, we wanted that experience to feel fluid and fast.
This is a look at how we made the conference platform and visuals, from ferrofluid-inspired 3D visuals and generative AI workflows, to modular component systems and more.
Search is changing. Backlinks and keywords aren’t enough anymore. AI-first interfaces like ChatGPT and Google’s AI Overviews now answer questions before users ever click a link (if at all). Large language models (LLMs) have become a new layer in the discovery process, reshaping how, where, and when content is seen.
This shift is changing how visibility works. It’s still early, and nobody has all the answers. But one pattern we're noticing is that LLMs tend to favor content that explains things clearly, deeply, and with structure.
"LLM SEO" isn’t a replacement for traditional search engine optimization (SEO). It’s an adaptation. For marketers, content strategists, and product teams, this shift brings both risk and opportunity. How do you show up when AI controls the first impression, but not lose sight of traditional ranking strategies?
Here’s what we’ve noticed, what we’re trying, and how we’re adapting.
You can now filter runtime logs to view fatal function errors, such as Node.js crashes, using the Fatal option in the levels filter.
When a log entry corresponds to a fatal error, the right-hand panel will display Invocation Failed in the invocation details.

An AI agent is a language model with a system prompt and a set of tools. Tools extend the model's capabilities by adding access to APIs, file systems, and external services. But they also create new paths for things to go wrong.
The most critical security risk is prompt injection. Similar to SQL injection, it allows attackers to slip commands into what looks like normal input. The difference is that with LLMs, there is no standard way to isolate or escape input. Anything the model sees, including user input, search results, or retrieved documents, can override the system prompt or event trigger tool calls.
If you are building an agent, you must design for worst case scenarios. The model will see everything an attacker can control. And it might do exactly what they want.
Beta access is now available for v0-1.5-md (128K token context) and v0-1.5-lg (512K token context) on our Models API.
For full details and examples, see the Models API docs: https://vercel.com/docs/v0/api
The AI Gateway, currently in alpha for all users, lets you switch between ~100 AI models without needing to manage API keys, rate limits, or provider accounts.
Vercel Observability now includes a dedicated AI section to surface metrics related to the AI Gateway. This update introduces visibility into:
Requests by model
Time to first token (TTFT)
Request duration
Input/output token count
Cost per request (free while in alpha)
You can view these metrics across all projects or drill into per-project and per-model usage to understand which models are performing well, how they compare on latency, and what each request would cost in production.
Learn more about Observability.
We've updated our build logic to ensure Git commits authored by Claude Code or Cursor Agent can trigger deployments on Vercel. A team seat is not required.
If your agent encounters any issues building on Vercel, please contact us.
Vercel Web Application Firewall's Bot Protection managed ruleset is now generally available for all users, at no additional cost.
Bot Protection helps reduce automated traffic from non-browser sources and allows you to respond based on two action choices:
Log Only Action: Logs identified bot traffic in the Firewall tab without blocking requests
Challenge Action: Serves a browser challenge to traffic from non-browser sources. Verified bots are automatically excluded
During the beta period, Bot Protection challenged over 650 million requests of potential non-browser requests.
Bot Protection complements Vercel's existing mitigations, which already block common threats like DDoS attacks, low quality traffic, and spoofed traffic. It adds an extra layer of protection for any automated traffic that is not clearly malicious.
Learn more about the Bot Protection managed ruleset and the Vercel Firewall. If you'd like your bot to be verified as well, head over to bots.fyi.
You can now pre-generate SSL certificates directly from the Vercel Domains dashboard, enabling zero-downtime domain migrations without using the CLI.
After adding an existing domain to your project, select Pre-Generate Certificate to issue certificates before updating DNS records and initiating the remainder of your domain migration.
You can still import a zone file or use Domain Connect to migrate DNS records from your previous provider.
Try it out or learn more in the docs.
AI agents are software systems that take over tasks made up of manual, multi-step processes. These often require context, judgment, and adaptation, making them difficult to automate with simple rule-based code.
While traditional automation is possible, it usually means hardcoding endless edge cases. Agents offer a more flexible approach. They use context to decide what to do next, reducing manual effort on tedious steps while keeping a review process in place for important decisions.
The most effective AI agents are narrow, tightly scoped, and domain-specific.
Here's how to approach building one.
You can now monitor and query Vercel Firewall challenge outcomes using two new metrics:
challenge-solved – Visitor solved the challenge and was granted access (indicates a real user)
challenge-failed – Visitor submitted an invalid challenge solution (the request was blocked)
These metrics help evaluate rule effectiveness and reduce friction when users are unnecessarily challenged (high success rates).
Now available in the Firewall dashboard and in the Observability Plus' query builder with no additional setup required.
Learn more about custom rules and managed rulesets.
We recently launched our AI models v0-1.5-md and v0-1.5-lg in v0.dev and v0-1.0-md via API. Today, we're sharing a deep dive into the composite model architecture behind those models. They combine specialized knowledge from retrieval-augmented generation (RAG), reasoning from state-of-the-art large language models (LLMs), and error fixing from a custom streaming post-processing model.
While this may sound complex, it enables v0 to achieve significantly higher quality when generating code. Further, as base models improve, we can quickly upgrade to the latest frontier model while keeping the rest of the architecture stable.
AI’s rapid evolution is reshaping the tech industry and app development. Traditional serverless computing was designed for quick, stateless web app transactions. LLM interactions require a different sustained compute and continuous execution patterns.
Fluid compute now supports both background and on-demand Incremental Static Regeneration (ISR) across all Vercel projects.
This means ISR functions now benefit from Fluid's performance and concurrency efficiency with no config changes needed. If you’ve redeployed recently, you’re already using it.
Fluid compute reuses existing resources before creating new ones, reducing costs by up to 85% for high-concurrency workloads. It delivers server-like efficiency with serverless flexibility with:
Optimized concurrency
Scale from zero to infinity
Minimal cold starts
Usage-based pricing
Full Node.js and Python support
No infrastructure management
Background tasks with waitUntil
Enable Fluid for your existing projects, and learn more in our blog and documentation.
The login experience has been redesigned for faster access and now includes full support for Google Sign-in, including Google One Tap.
If your existing Vercel account's email matches your Google email, you can use the Google button from the login screen and your accounts will be automatically linked.
If the emails don’t match, you can manually connect your Google account from your account settings once logged in.
Observability Plus users can now use natural language to create new queries or modify existing ones by adding filters, changing time ranges, or grouping results.
Queries allow customers to explore log data and visualize traffic, performance, and other key metrics.
AI prompts generate queries in the standard format, and are represented in the URL so they can be shared and bookmarked.
Example prompts include:
Show all 500 errors in the last 24 hours
Show me the top bandwidth for incoming requests
Show me the top hostnames grouped by country
All requests challenged by DDoS mitigations by user agent
Find all requests with the keyword "timeout" grouped by path
This is available to all Observability Plus users at no additional cost.

A low-severity vulnerability in the Next.js dev server has been addressed.
This vulnerability affects Next.js versions 13.0.0 through 14.2.29 and 15.0.0 through 15.2.1. It includes two related issues affecting the local development server: Cross-Site WebSocket Hijacking (CSWSH) and Cross-Origin Script Inclusion. Both stem from the lack of origin validation on development server resources.
When running next dev, a malicious website can:
Initiate a WebSocket connection to localhost and interact with the local development server if the project uses the App Router, potentially exposing internal component code.
Inject a <script> tag referencing predictable paths for development scripts (e.g., /app/page.js), which are then executed in the attacker's origin. This can allow extraction of source code
The root cause is insufficient origin verification on local development server resources, including the WebSocket server and static script endpoints. This issue is similar to CVE-2018-14732, though scoped strictly to local development use.
This issue was fixed in Next.js versions 14.2.30 and 15.2.2. These releases introduce a configuration option to enable origin checks, which help prevent unauthorized cross-origin requests to the local development server. You can learn how to enable this option after upgrading to a patched version by visiting our documentation page. Note that this configuration is currently opt-in and will become the default in a future major release.
Avoid browsing untrusted websites while running the local development server
Implement local firewall or proxy rules to block unauthorized access to the development server
This CVE affects local development, no mitigation are required for applications in production on Vercel.
Thanks to sapphi-red and Radman Siddiki for responsibly disclosing this issue.
Since February, Vercel blocked 148 billion malicious requests from 108 million unique IP addresses. Every deployment automatically inherits these protections, keeping your workloads secure by default and enabling your team to focus on shipping rather than incidents. Our real-time DDoS filtering, managed Web Application Firewall (WAF), and enhanced visibility ensure consistent, proactive security.
Here's what's new since February.
The Vercel Observability dashboard now includes a dedicated view for middleware, showing invocation counts and performance metrics.

These changes are now effective and have been automatically applied to your account.
Learn more about configuring rate limits or create a new rate limiting rule now.
We’ve optimized connection pooling in our CDN to reduce latency when connecting to external backends, regardless of traffic volume.
Lower latency: Improved connection reuse and TLS session resumption reduce response times by up to 60% in some regions, with a 15–30% average improvement.
Reduced origin load: 97% connection reuse and more efficient TLS resumption significantly cut the number of new handshakes required.
This is now live across all Vercel deployments at no additional cost.
The Observability dashboard now surfaces caching behavior for external API calls using Vercel Data Cache.
External APIs page, you’ll see a new column indicating how many requests were served from the cache vs. the origin.
Caching insights are available per hostname for all users, and per path for Observability Plus subscribers.
View the external API dashboard or learn more about Vercel Data Cache.
Vercel recently published a Model Context Protocol (MCP) adapter that makes it easy to spin up an MCP server on most major frameworks.
Vapi is building an API for building real-time voice agents. They handle orchestration, scaling, and telephony to provide a completely model-agnostic and interchangeable interface for building agents.
Vapi rebuilt their MCP server on Vercel, letting users create agents, automate testing, analyze transcripts, build workflows, and give agents access to all of Vapi’s endpoints.
Storage should be simple to set up, globally available, and built to last, without slowing you down or adding complexity. It should feel native to your app.

Since 2014, Consensys has shaped the web3 movement with tools like and Linea, Infura, and MetaMask—the most widely used self-custodial wallet on the web, with millions of users across the globe.
As the blockchain ecosystem quickly matured, the need for a site that could move as fast as the teams building it became clear. To meet that demand, Consensys migrated MetaMask.io to Next.js and Vercel, creating an architecture built for scale, speed, and continuous iteration.
We’re updating how pricing works in v0. Usage is now metered on input and output tokens which convert to credits, instead of fixed message counts.
This gives you more predictable pricing as you grow and increases the amount of usage available on our free tier.
Existing v0 users will transition to the new pricing at the start of your next billing period. New users will start on the improved pricing today.
Vercel’s CDN, which can proxy requests to external backends, now caches proxied responses using the CDN-Cache-Control and Vercel-CDN-Cache-Control headers. This aligns caching behavior for external backends with how Vercel Functions are already cached.
This is available starting today, on all plans, at no additional cost.
Per the Targeted HTTP Cache Control spec (RFC 9213), these headers support standard directives like max-age and stale-while-revalidate, enabling fine-grained control over CDN caching without affecting browser caches.
You can return the headers directly from your backend, or define them in vercel.json under the headers key if your backend can't be modified.
No configuration changes or redeployments required. Return the header (or set it in vercel.json) to improve performance, reduce origin load, and ensure fresh content.
Learn more about CDN-Cache-Control headers.
You can now block AI crawlers and scrapers like GPTBot (OpenAI), ClaudeBot (Anthropic), PerplexityBot, Bytespider (ByteDance), and others with a single toggle using the AI bot managed ruleset. Now available for free on all plans.
The ruleset is managed by Vercel and updates automatically as new crawlers appear, with no additional action required. This protection operates with zero latency impact to legitimate traffic.
For more complete coverage, combine with Bot Filter to catch AI bots that attempt to spoof user agents to disguise themselves as legitimate browsers or omit proper identification headers.
AI crawlers now generate more traffic than human users on many popular sites, driving up infrastructure costs and raising copyright and data usage concerns. Many of these crawlers do not respect robots.txt or similar directives, making manual solutions unreliable.
Enable the ruleset or learn more in the documentation.
The Resources tab is replacing the Functions tab for deployments in the Vercel Dashboard, allowing you to see more than Functions. You'll now see the Resources tab when viewing a deployment in the Vercel Dashboard where you can see, search, and filter:

Vercel’s CDN will now wait up to 120 seconds for your backend to start sending data, up from 30 seconds. This extended proxied request timeout is now available on all plans at no additional cost.
The proxied request timeout defines how long our CDN allows your external backend to respond before canceling the request. After the initial byte is received, your backend can take longer than two minutes to complete the request, as long as it continues sending data at least once every 120 seconds.
This update improves reliability for workloads with long processing times, such as LLM generation or complex data queries, and reduces the chance of 504 gateway timeouts.
This change is effective immediately, with no action or configuration required.
We’ve increased included limits and reduced the price of Web Analytics event and the Web Analytics Plus add-on by up to 80%.
Web Analytics is now billed:
Per single event, instead of 100K increments
At $0.00003 per event ($3 per 100K, a 79% decrease from $14 per 100K)
At $10/month for the Plus add-on (an 80% decrease, from $50/month)
Web Analytics Plus is an optional add-on that unlocks increased retention and UTM parameters.
Included event limits have increased:
Hobby: 50K events/month (20x increase, from 2.5K)
Pro: 100K events/month (4x increase, from 25K)

Experimentation, A/B testing, and feature flags serve as essential tools for delivering better user experiences, ensuring smoother rollouts, and empowering teams to iterate quickly with confidence. We're making it easier to bring flags into your workflow with:
Model Context Protocol (MCP) is a way to build integrations for AI models.
Vercel now supports deploying MCP servers (which AI models can connect to) as well as MCP clients (AI chatbot applications which call the servers).
Get started with our Next.js MCP template today.
APIs allow different services to communicate together. MCP is slightly different.
Rather than thinking about MCP like a REST API, you can instead think about it like a tailored toolkit that helps an AI achieve a particular task. There may be multiple APIs and other business logic used behind the scenes for a single MCP tool.
If you are already familiar with tool-calling in AI, MCP is a way to invoke tools hosted on a different server.
MCP now supports a protocol similar to other web APIs, namely using HTTP and OAuth. This is an improvement from the previous stateful Server-Sent Events (SSE) protocol.
To simplify building MCP servers on Vercel, we’ve published a new package, @vercel/mcp-adapter, which supports both the older SSE transport and the newer stateless HTTP transport.
The majority of MCP clients currently only support the SSE transport option. To handle state required for the SSE transport, you can integrate a Redis server through any provider in our marketplace like Upstash and Redis Labs.
We’ve already seen customers successfully deploying MCP servers in production. One customer has seen over 90% savings using Fluid compute on Vercel versus traditional serverless. Fluid enables you to have full Node.js or Python compatibility, while having a more cost effective and performant platform for AI inference and agentic workloads.
Vercel's AI SDK has built-in support for connecting your Node.js or Next.js apps to MCP servers.
We’re looking forward to future MCP servers built with the HTTP transport and starting to explore the latest developments like OAuth support.
Other Vercel projects like shadcn/ui are exploring ways to integrate MCP. If you have suggestions for MCP server use cases on Vercel, you can share your feedback in our community.
Vercel Observability now provides detailed breakdowns for individual bots and bot categories, including AI crawlers and search engines. Users across all plans can view this data in the Observability > Edge Requests dashboard.
Additionally, Observability Plus users can:
Filter traffic by bot category, such as AI
View metrics for individual bots
Break down traffic by bot or category in the query builder
Inspect bot and crawler activity in your Observability dashboard now.
The Flags Explorer lets you override feature flags for your own session, without affecting colleagues, and without signing into your flag provider. This enables you to test features in production before they go live and keeps you in the flow.
This feature is now generally available for all customers. Hobby, Pro, and Enterprise plans include 150 overrides per month, with unlimited overrides available for $250 per month on Pro and Enterprise.
Teams that used Flags Explorer during the beta have 30 days to activate the new unlimited option before the 150 overrides per month limit takes effect. This can be done in the Vercel dashboard or directly through the Vercel Toolbar.
Additionally, The Flags SDK automatically respects overrides set by the Flags Explorer, no matter which adapter you're using.
Projects with on-demand concurrent builds can now use enhanced build machines to improve build performance.
Available on all paid plans, these machines offer double the resources: 8 CPUs, 16 GB memory, and 58 GB disk. This reduces both build time and total build minutes used. Existing customers are already seeing up to 25% faster builds with no changes required.
Enhanced builds can be enabled per project and are billed per minute.
Enterprise customers can run all concurrent builds, including pre-allocated build slots and on-demand, on higher-spec machines.
Enable on-demand enhanced builds and learn more in our documentation.
The Vercel AI Accelerator is back. This year, we'll work with 40 teams building the future of AI. Over six weeks, participants get the tools, infrastructure, and support to create next-generation AI apps.
Applications are open now until May 17.
Session tracing is now available to all Vercel users, providing end-to-end visibility into the timing of each step in a request's lifecycle, from when it enters Vercel’s infrastructure to execution inside your Vercel Functions.
With session tracing you can:
Start tracing sessions on your deployments directly from the Vercel Toolbar, no setup required.
View spans for Vercel's routing, caching, middleware, and function layers as well as those instrumented in your code.
Share traces with teammates for faster debugging and optimization.
Use tracing alongside logs and metrics to debug, optimize, and improve iteration speed.
Session tracing is free to customers on all plans.
To get started, find Tracing in the Vercel Toolbar, or learn more in the docs.
Building for the web goes beyond speed and aesthetics, discoverability matters just as much. While AI can accelerate web development, it often skips over performance, accessibility, or SEO best practices that matter for discoverability. With v0, you don’t have to compromise. Every interface you generate is fast, accessible, and SEO-optimized by default.
v0 integrates with Next.js and deploys to Vercel, giving you structured metadata, performance tuning, and Server Side Rendering (SSR). The result is better Core Web Vitals, pages that load quickly and return full HTML, making them easier for search engines to crawl and index.
Vercel discovered and patched an information disclosure vulnerability in the Flags SDK, affecting versions:
flags ≤ 3.2.0
@vercel/flags ≤ 3.1.1
This is being tracked as CVE-2025-46332. We have published an automatic mitigation for the default configuration of the Flags SDK on Vercel.
We recommend upgrading to flags@4.0.0 (or migrating from @vercel/flags to flags) to remediate the issue. Further guidance can be found in the upgrade guide.
A malicious actor could determine the following under specific conditions:
Flag names
Flag descriptions
Available options and their labels (e.g. true, false)
Default flag values
Flags providers were not accessible. No write access nor additional customer data was exposed, this is limited to the values noted above.
Vercel implemented a network-level mitigation to prevent the default flags discovery endpoint at /.well-known/vercel/flags being reachable, which automatically protects Vercel deployments against exploitation of this issue.
While uncommon, if you are exposing the flags discovery endpoint through custom paths, you can also implement a custom WAF rule to restrict access to these endpoints as a mitigation, for example when using:
Pages Router, as the original non-rewritten route would still be accessible, e.g. /api/vercel/flags
Microfrontends, as each application may use a distinct flags discovery endpoint
We recommend that all users upgrade to flags@4.0.0. Flags Explorer will be disabled and show a warning notice until you upgrade to the latest version.
More information can be found in the upgrade guide.
Vercel now fully supports the HTTP Vary header, making it easier to cache personalized content across all plans with no configuration required.
The Vary header tells caches which request headers to include when generating cache keys. This allows Vercel’s application delivery network to store and serve different versions of a page based on headers like X-Vercel-IP-Country or Accept-Language, so users get fast, localized content without recomputation.
By returning the above headers your site caches and serves country-specific content.
A visitor from the United States receives the US-specific cached version, and visitors from other countries receive the version for their locale, with no recomputation required.
Learn more about caching personalized content in Vercel's application network documentation.
Yesterday, a federal court made a decisive ruling in Epic Games v. Apple: Apple violated a 2021 injunction by continuing to restrict developers from linking to external payment methods, and by imposing a 27% fee when they did.
The ruling represents a major shift for native app developers.
You can now create custom WAF rules directly from the chart displayed on the Firewall tab of the Vercel dashboard.
When viewing your traffic grouped by a parameter (like IP address, user agent, or request path), you can now select "Create Custom Rule" within the actions menu of any displayed time series. This automatically generates an editable draft of the custom WAF rule that matches the selected parameter.
Once the WAF rule is saved and published, it's immediately propagated across our global network.
This feature is available to all users across all plans at no additional cost.
Learn more about the Vercel Firewall.
You can now disable the deployment_status webhook event that Vercel sends to GitHub when Vercel is connected to your GitHub repository.
When deployment_status events are enabled, GitHub's pull request activity will create a log with a status event for every deployment. While this can keep your team better informed, it can also create noisy event logs for repositories with many deployment events, especially in monorepos with many projects.
Disabling these events prevents repeated messages from cluttering your GitHub PR's event history, giving you a cleaner, more focused view of your pull request activity. The Vercel Github comment containing links to your preview deployments will continue to be posted as before.
The deployment_status event is most often used as a trigger for GitHub Actions. We recommend migrating to repository_dispatch events to simply workflows with richer Vercel deployment information.
Providers building native integrations for the Vercel Marketplace can now use the Checks API to deliver deeper functionality for their users.
With Vercel's Checks API, you can define and run custom tests and assertions after every deployment, then surface actionable results directly in the Vercel dashboard.
As a testing provider, you can implement checks such as reliability tests (e.g. API availability, runtime errors), performance tests (e.g. response time thresholds, load simulation), or Web Vitals (e.g. layout shift). This helps developers catch real-world issues earlier in their workflow, powered by your integration.
When building your integration, keep these best practices in mind:
Offer minimal or no-configuration solutions so developers can easily run checks
Provide a guided onboarding experience from installation to first results
Display clear, actionable outcomes directly in the Vercel dashboard
Document ways to extend or customize checks for advanced users
Learn more in the Checks API documentation.
Security researchers reviewing the Remix web framework have discovered two high-severity vulnerabilities in React Router. Vercel proactively deployed mitigation to the Vercel Firewall and Vercel customers are protected.
CVE-2025-43864 and CVE-2025-43865 enable an external party to modify the response using certain request headers, which can lead to cache poisoning Denial of Service (DoS). CVE 43865 enables vulnerabilities such as stored Cross Site Scripting (XSS).
When we learned about the vulnerability, we started analyzing the impact to the Vercel platform. Here are our findings and recommendations:
We were able to reproduce the vulnerability and demonstrate that cache poisoning is trivial, including stored Cross Site Scripting (XSS) injections
The only precondition is that the customer used an impacted version of Remix / React Router (v7.0.0 branch prior to version v7.5.2) and Cache-Control headers
The impact can extend to any visitor of the application after the cache is poisoned, regardless of authentication state or any other request headers
Vercel customers using React Router between v7.0.0 and v7.5.1 were impacted before our Firewall mitigation
We have deployed mitigations for attacks by stripping the X-React-Router-Spa-Mode and X-React-Router-Prerender-Data headers from the request in the Vercel Firewall. New requests are now protected across all deployments on the Vercel platform. We confirmed our mitigation approach with the Remix / React Router team.
In addition to mitigating future requests, we have preemptively purged CDN response caches on our network out of caution.
Both issues have been patched in React Router 7.5.2. We recommend updating to the latest version and redeploying.
If you are using additional layers of caching, including Cloudflare or other CDNs, we recommend purging those caches separately. Thank you to zhero for disclosing the vulnerability.
We’ve redesigned the Project Domains page with faster search, smoother navigation, and clearer visibility into your domain configurations.
Navigating and understanding your domain setup is now quicker and more direct:
Live Search: Start typing in the search bar, and your domain list will filter as you type without needing an exact match.
Infinite Scroll: We've replaced the "View More" button with smooth, infinite scrolling so you can browse without interruptions.
Cleaner View: Key information like associated Redirects and Environments are now displayed inline within the domain list, giving you a comprehensive overview at a glance without needing to click into individual domain details.
Configuring DNS and adding new domains is now more focused and user-friendly:
Focused DNS Configuration in Modals: We’ve moved the DNS configuration instructions into a modal. This allows you to focus solely on configuring the domain you’ve added.
Guided Full-Page Add Flow: Adding a new domain is now a clearer, step-by-step process with our new full-page add flow. We guide you through the necessary configurations to ensure a correct setup from the start.
Smarter Domain Validation: We’ve added better validation to input, improved error messages around adding wildcard domains, and improved clarity around adding www & apex domains.
To learn more about managing Domains on Vercel, read the docs.
When multiple team members deploy to Vercel at once, builds by default have a queue. Now, you can remove these queues, enabling your builds to start immediately.
This is available to both Pro and Enterprise customers with new per-minute pricing and can be applied in the following ways:
Manually, per deployment, for urgent builds
Automatically, at the project level, to avoid queues by default
Concurrent build slots remain available for teams with steady, high-volume workloads.
Learn about on-demand concurrent builds and enable them on your project.
Pricing for on-demand concurrent builds, which allow deployments to bypass build queues, has been reduced by more than 50%. Usage increments have also been lowered from 10 minutes to 1 minute.
On-demand concurrent builds are available to both Pro and Enterprise customers, and complement existing build slots with the following recommendations:
Use on-demand for bursty workloads or priority deploys
Use slots for large, frequent builds with predictable volume
This change also applies to all customers using Enhanced On-demand builds, which allocate more memory to build compute for faster deployment times.
Learn about on-demand concurrent builds and enable them on your project.
You can now customize keyboard shortcuts for the Vercel Toolbar. Replace default shortcuts for hiding and opening the Toolbar Menu, and add shortcuts for frequently used tools.
To configure shortcuts, find Keyboard Shortcuts under Preferences in the Toolbar Menu. The browser extension is needed to customize shortcuts for hiding the toolbar and opening the Toolbar Menu.
The default shortcut to show and hide the Toolbar Menu is changing to reduce conflicts with sites that have their own Cmd+K menus.
Mac: changing from ⌘ K to ^ (control)
Windows: changing from Ctrl K to Ctrl

The Vercel Web Application Firewall (WAF) inspects billions of requests every day to block application-layer threats, such as cross-site scripting, traversal, and application DDoS attacks. While we already inspect and block malicious bot traffic, we wanted to provide better, more precise controls to fine tune your application security.
Today, we're launching the Bot Protection managed ruleset, free for all users on all plans. With a single click, you can protect your application from bot attacks.
Vercel Web Application Firewall now includes a new Bot Protection managed ruleset, available in public beta for all users.
Bot Protection helps reduce automated traffic from non-browser sources and allows you to respond based on two action choices:
Log Only Action: Logs identified bot traffic in the Firewall tab without blocking requests
Challenge Action: Serves a browser challenge to traffic from non-browser sources. Verified bots are automatically excluded
To avoid disrupting legitimate automated traffic that's not already covered by Verified Bots, you can configure custom WAF rules using the bypass action for specific requests.
To enable the ruleset:
In your project dashboard, navigate to the Firewall tab and select Configure
Under Bot Management, navigate to Bot Protection
Select Log or Challenge
Select Review Changes and review the changes to be applied
Select Publish to apply the changes to your production deployment
Bot Protection complements Vercel's existing mitigations, which already block common threats like DDoS attacks, low quality traffic, and spoofed traffic. It adds an extra layer of protection for any automated traffic that is not clearly malicious.
During this public beta period, we’ve set up a thread on the Vercel Community where you can share your feedback, feature requests, and experiences with Bot Protection.
Learn more about the Bot Protection managed ruleset and the Vercel Firewall. Edit: During the beta period, we renamed the Bot Filter managed ruleset to Bot Protection

Vercel Functions using Node.js can now detect when a request is cancelled and stop execution before completion. This includes actions like navigating away, closing a tab, or hitting stop on an AI chat to terminate compute processing early.
This reduces unnecessary compute, token generation, and sending data the user never see.
You can listen for cancellation using Request.signal.aborted or the abort event:
If you're using the AI SDK, forward the abortSignal to your stream:
Learn more about cancelling Function requests.
New Vercel projects now run on Fluid compute by default.
This update follows Fluid’s general availability, its adoption across large-scale production apps, and all v0.dev deployments shipping with Fluid enabled by default.
Fluid compute reuses existing instances before spawning new ones, cutting costs by up to 85% for high-concurrency workloads. It combines the efficiency of servers with the flexibility of serverless:
Concurrent requests per function
Scale from zero to infinity
Minimal cold starts
Usage-based, pay as you go
Full Node.js and Python support
No infrastructure to manage
Background tasks with waitUntil
Enable Fluid for your existing projects, and learn more in our blog and documentation.
A low severity cache poisoning vulnerability was discovered in Next.js.
This affects versions >14.2.24 through <15.1.6 as a bypass of the previous CVE-2024-46982. The issue happens when an attacker exploits a race condition between two requests — one containing the?__nextDataRequest=1 query parameter and another with the x-now-route-matches header.
Some CDN providers may cache a 200 OK response even in the absence of explicit cache-control headers, enabling a poisoned response to persist and be served to subsequent users.
Next.js versions >14.2.24 through <15.1.6
This vulnerability allows an attacker to poison the CDN cache by injecting the response body from a non-cacheable data request (?__nextDataRequest=1) into a normal request that retains cacheable headers, such as Cache-Control: public, max-age=300.
No backend access or privileged escalation is possible through this vulnerability.
This issue was verified using automated tooling that repeatedly triggers the race condition. Successful exploitation depends on precise timing and the presence of a vulnerable CDN configuration. A Python-based proof of concept script was shared by the reporter and used to validate this behavior on live targets prior to the patch.
This issue was patched in 15.1.6 and 14.2.24 by stripping the x-now-route-matches header from incoming requests.
Applications hosted on Vercel's platform are not affected by this issue, as the platform does not cache responses based solely on 200 OK status without explicit cache-control headers.
For self-hosted Next.js deployments unable to upgrade immediately, you can mitigate this vulnerability by:
Stripping the x-now-route-matches header from all incoming requests at your CDN
Setting cache-control: no-store for all responses under risk
We strongly recommend only caching responses with explicit cache-control headers.
Thank you to Allam Rachid (zhero;) for the responsible disclosure. They were awarded as part of our bug bounty program.
In today's rapidly evolving tech landscape, AI has moved from research labs to everyday tools with stunning speed. I wanted to share my perspective, not only as a CTO at Vercel, but as an engineer who's seen a few revolutions over the past 30 years.
Security researchers reviewing the Remix web framework have recently discovered a high-severity vulnerability in React Router that allows URL manipulation through the Host/ X-Forwarded-Host header.
Our investigation determined that Vercel and our customers are unaffected:
We use query parameters as part of the cache key, which protects against cache poisoning driven by the _data query praram.
The @vercel/remix adapter uses X-Forwarded-Host similarly to the Express adapter, but it is not possible for an end user to send X-Forwarded-Host to a Function hosted on Vercel.
A patch has been issued and released in Remix 2.16.3 / React Router 7.4.1. We recommend customers update to the latest version.
Read more about CVE-2025-31137.
Today we are lowering the price of Fast Data Transfer (FDT) for Vercel regions in Asia Pacific, Latin America, and Africa by up to 50%.

Enhanced Builds now offer double the compute capacity, further improving performance for large codebases and CPU-intensive builds.
Available to Enterprise customers, Enhanced Builds are designed for teams working with monorepos or frameworks that run tasks in parallel—like dependency resolution, transpilation, or static generation.
Customers already using Enhanced Builds are seeing, with no action required, up to 25% reductions in build times.
Learn more in our documentation or speak to your Vercel account team to enable Enhanced Builds.
Routing is a fundamental part of delivering applications, but it’s often treated as an afterthought—tacked onto the caching layer and configured through complex YAML or manual click-ops. This can introduce friction for teams, increase the risk of misconfigurations, and slow down deployments, especially as applications grow in complexity.
Vercel takes a different approach: routing is built into the platform as an application-aware gateway that understands your codebase. This unlocks a range of capabilities that simplify development by reducing configuration overhead, minimizing latency, and enabling more advanced architectures.
The gateway has full context of your deployments, domains, and logic. It supports standard routing and custom rules, but goes beyond reverse proxying by interpreting application logic in real time to make smarter decisions, like skipping unnecessary compute.
Here’s how Vercel routes requests—and why it makes building performant, complex apps easier.
A Spanish court has granted LALIGA the power to block IP addresses associated with unauthorized football streaming—without distinguishing between infringing and non-infringing services. As a result, legitimate, unrelated websites that people depend on are now inaccessible in Spain.
Grep is extremely fast code search. You can search over a million repositories for specific code snippets, files, or paths. Search results need to appear instantly without loading spinners.
Originally built with Create React App (CRA) as a fully client-rendered Single-Page App (SPA), Grep was fast—but with CRA now deprecated, we wanted to update the codebase to make it even faster and easier to maintain going forward.
Here's how we migrated Grep to Next.js—keeping the interactivity of a SPA, but with the performance improvements from React Server Components.
SvelteKit routes with dynamic segments—like /blog/[slug]—are now individually recognized and surfaced by Vercel Observability. This replaces the previous behavior where all dynamic routes appeared under a single /fn entry.
This is available with version 5.7.0 of @sveltejs/adapter-vercel. Upgrade to unlock improved observability for your SvelteKit projects.
Learn more about Vercel Observability.

The Vercel Marketplace adds new integrations from Sentry, Checkly, and Dash0. You can now use the tools you already trust to monitor, measure, and debug your apps. No custom setup. No change to how you build or deploy.
These tools connect directly through the Vercel Marketplace with integrated billing, single sign-on, and access to provider dashboards, giving you deep visibility without the setup overhead.
Google and Bing web crawlers occasionally crawl a document, but render it up to several weeks later using a headless browser. This delay between document crawl and assets download (which happens during render) can cause indexing failures if the website has been re-deployed since the crawl.
Vercel now automatically protects against such indexing failures for projects that have Skew Protection enabled.
This was achieved by extending the maximum age for Skew Protection to 60 days for requests coming from major search engine bots, such as Googlebot and Bingbot. This means that assets deployed up to 60 days ago will still be accessible to search engines when they render your document.
Regardless of the maximum age configured in the dashboard, Pro and Enterprise accounts using Skew Protection will automatically be protected from this delay, thereby improving SEO.
Learn more about Skew Protection and enable it in your project. Also, check out our SEO research on how Google handles JavaScript throughout the indexing process, which provides a deeper dive into the search rendering process.
New native integrations from Sentry, Checkly, and Dash0 are now available on the Vercel Marketplace, helping make it easier to monitor, debug, and optimize your applications—all in one place.
Sentry: Real-time error tracking and performance monitoring for faster issue resolution
Checkly: End-to-end monitoring and synthetic checks for your frontend and APIs
Dash0: Log management and structured observability, built with a developer-first experience. Dash0 also supports Native Log Drains, allowing you to stream logs from your Vercel projects to external logging systems for deeper insights and centralized monitoring
This launch introduces Log Drain support for native integrations—a capability that was previously only available to connectable accounts.
These integrations offer frictionless onboarding, single sign-on, and integrated billing through Vercel, making it easy to get started in just a few clicks.
Explore the new observability integrations.
Securing web applications is core to the Vercel platform. It’s built into every request, every deployment, every layer of our infrastructure. Our always-on Denial-of-Service (DoS) mitigations have long run by default—silently blocking attacks before they ever reach your applications.
Last year, we made those always-on mitigations visible with the release of the Vercel Firewall, which allows you to inspect traffic, apply custom rules, and understand how the platform defends your deployments.
Now, we’re introducing Protectd, our next-generation real-time security engine. Running across all deployments, Protectd reduces mitigation times for novel DoS attacks by over tenfold, delivering faster, more adaptive protection against emerging threats.
Let's take a closer look at how Protectd extends the Vercel Firewall by continuously mapping complex relationships between traffic attributes, analyzing, and learning from patterns to predict and block attacks.
You can now trigger GitHub Actions workflows in response to Vercel deployment events with enriched data using repository_dispatch events. These events are sent from Vercel to GitHub, enabling more flexible, cost-efficient CI workflows, and easier end-to-end testing for Vercel deployments.
Previously, we recommended using deployment_status events, but these payloads were limited and required extra parsing or investigation to understand what changed.
With repository_dispatch, Vercel sends custom JSON payloads with full deployment context—allowing you to reduce Github Actions overhead and streamline your CI pipelines.
We recommend migrating to repository_dispatch for a better experience. deployment_status events will continue to work for backwards compatibility.

Learn more about Secure Compute.
Users can now secure their accounts using Two-Factor Authentication (2FA) with Time-based One-Time Passwords (TOTP), commonly provided by authenticator apps like Google Authenticator or Authy. Your current Passkeys (WebAuthn keys) can also be used as second factors. 2FA adds an extra security layer to protect your account even if the initial login method is compromised.
To Enable 2FA:
Navigate to Authentication in Account Settings and enable 2FA
Log in using your existing method (email OTP or Git provider) as your first factor
Complete authentication with a TOTP authenticator as your second factor
Important information:
Passkey logins (WebAuthn) are inherently two-factor and won't prompt for additional verification
Team-scoped SAML SSO logins delegate authentication responsibility to your identity provider (IdP) and won't require an additional factor within Vercel
Visit your account settings to enable 2FA today, or check out our documentation to learn more.
In the process of remediating CVE-2025-29927, we looked at other possible exploits of Middleware. We independently verified this low severity vulnerability in parallel with two reports from independent researchers.
To mitigate CVE-2025-29927, Next.js validated the x-middleware-subrequest-id which persisted across multiple incoming requests:
However, this subrequest ID is sent to all requests, even if the destination is not the same host as the Next.js application.
Initiating a fetch request to a third-party within Middleware will send the x-middleware-subrequest-id to that third party.
While the exploitation of this vulnerability is unlikely due to an attacker requiring control of the third-party, we want to be proactive. We were already planning on removing this recursion prevention logic from Middleware—it was not supported in newer updates to Middleware to support the Node.js runtime—this disclosure expedited our efforts to bring parity between runtimes.
Vercel customers are protected with mitigations already implemented within our platform environment. We still encourage teams to update to the latest Next.js patch version or their chosen backport. Other infrastructure providers which host Next.js applications are not impacted by this, as it is specific to Vercel's implementation of recursion protection.
This advisory was published in alignment with our new internal process for disclosure of vulnerabilities within OSS packages, based on our postmorten of CVE-2025-29927. We’ve patched 15.x, and offered backports for versions 12.x through 14.x, making an exception to our newly published LTS policy.
We’ve also worked proactively with new partners to Next.js for early disclosure. If you are an infrastructure provider and want to work with us, please email partners@nextjs.org.
Thank you to Jinseo Kim (kjsman) and ryotak for the responsible disclosure. These researchers were awarded as part of our bug bounty program.
Composable commerce projects frequently become overly complex, leading to missed objectives and unnecessary costs. At Vercel, we take a no-nonsense approach to composable commerce that's solely focused on business outcomes. Architecture should serve the business, not the other way around. Ivory tower architectures disconnected from clear business goals inevitably lead to projects plagued by runaway costs. Here are five truths we stand by when it comes to composable commerce:
Verified webhook providers—including Stripe and PayPal—are now automatically allowed in Attack Challenge Mode, ensuring uninterrupted payment processing. Well-behaved bots from major search engines, such as Googlebot, and analytics platforms are also supported.
Vercel Cron Jobs are now exempt from challenges when running in the same account. Like other trusted internal traffic, they bypass Attack Challenge Mode automatically.
To block specific known bots, create a custom rule that matches their User Agent. Known bots are validated to be authentic and cannot be spoofed to bypass Attack Challenge Mode.
Learn more about Attack Challenge Mode and how Vercel maintains its directory of legitimate bots.
Vercel now caches dependencies for projects using Yarn 2 and newer, reducing install times and improving build performance. Previously, caching was only supported for npm, pnpm, Bun, and Yarn 1.
To disable caching, set the environment variable VERCEL_FORCE_NO_BUILD_CACHE with a value of 1 in your project settings.
If you're using Yarn 4, enable Corepack, as recommended by Yarn.
Visit the Build Cache documentation to learn more.
The Flags SDK 3.2 release adds support for precomputed feature flags in SvelteKit, making it easier to experiment on marketing pages while keeping them fast and avoiding layout shift.
Precomputed flags evaluate in Edge Middleware to decide which variant of a page to show. This keeps pages static, resulting in low global latency as static variants can be served through the Edge Network.
Precompute handles the combinatory explosion when using multiple feature flags statically. Generate different variants of a page at build time, rely on Incremental Static Regeneration to only build a specific combinations on demand, and more.
We also improved the Flags SDK documentation by splitting it across different frameworks and explicitly listing all providers that have adapters for the Flags SDK.
Learn more about the Flags SDK with SvelteKit and the precompute pattern.
Last week, we published CVE-2025-29927 and patched a critical severity vulnerability in Next.js. Here’s our post-incident analysis and next steps.
A security vulnerability in Next.js was responsibly disclosed, which allows malicious actors to bypass authorization in Middleware when targeting the x-middleware-subrequest header.
Vercel customers are not affected. We still recommend updating to the patched versions. Learn more about CVE-2025-29927.
The Flags SDK adapter for OpenFeature allows using any Node.js OpenFeature provider with the Flags SDK. Pick from a wide range of flag providers, while benefiting from the Flag SDK's tight integration into Next.js and SvelteKit.

Vercel now maps dependencies in your package manager’s lockfile to applications in your monorepo. Deployments only occur for applications using updated dependencies.
This feature is based on Turborepo's lockfile analysis, supporting the package managers listed as stable in Turborepo's Support Policy.
Previously, any change to the lockfile would redeploy all applications in the monorepo since it was treated as a shared input. Now, Vercel inspects the lockfile’s contents to determine which applications have dependency changes, further reducing potential queue times.
Learn more about skipping unaffected projects in monorepos.
We have deployed a proactive security update to the Vercel Firewall, protecting against a recently disclosed vulnerability in the xml-crypto package, dubbed SAMLStorm (CVE-2025-29774 and CVE-2025-29775). This vulnerability, which affects various SAML implementations, could allow attackers to bypass authentication mechanisms.
Automatic protection with the Vercel Firewall: Vercel Firewall automatically mitigates this risk for you, but updating xml-crypto is still recommended
Update xml-crypto: If you're using xml-crypto package 6.0.0 and earlier, or a package that depends on xml-crypto, update to 6.0.1, 3.2.1, or 2.1.6 for the patched versions
We'll continue to monitor for new developments and provide updates as necessary
See the SAMLStorm report for more details on the vulnerability, and reach out to Vercel Support if you have questions.

Bulk aliasing for multi-tenant applications now runs significantly faster, reducing total aliasing time by up to 95%.
Multi-tenant applications on Vercel let a single project serve many customers behind the scenes. These applications are often fronted by hundreds or thousands of domains. Previously, aliasing—the process of pointing a domain to a different deployment—was a slow process that added significant overhead to deployments.
This optimization is now live for all customers and has led to dramatic improvements, like:
App with 13,254 domains: ~10min → 28 seconds
App with 23,743 domains: 8min 37secs → 26 seconds
Learn more about multi-tenant applications on Vercel.
When I started Vercel, my vision was simple: make building for the web more accessible and more powerful. That belief has fueled Vercel’s growth, empowering developers to bring their biggest ideas to life.
Today, we’re welcoming Jeanne DeWitt Grosser, former Chief Business Officer at Stripe, as Vercel’s Chief Operating Officer to help further this mission. Vercel is building the foundation to power the next billion developers. Achieving this vision requires strong leadership and operational excellence. As COO, Jeanne will lead our go-to-market function.
Personalization works best when it’s intentional. Rushing into it without the right approach can lead to higher costs, slower performance, and poor user experience. The key is to implement incrementally, with the right tools, while maintaining performance.
When personalization is implemented effectively, it drives real business results, returning $20 for every $1 spent and driving 40% more revenue.
Let's look at what personalization is, how to implement it correctly, and why Next.js and Vercel achieve optimal outcomes.
We've increased Image Optimization included usage for Hobby teams:
Image Transformations: from 3K to 5K per month
Image Cache Reads: from 180K to 300K per month
Image Cache Writes: from 60K to 100K per month

Each metric also serves as a starting point for deeper analysis, with one-click access to their dedicated dashboards for more detailed insights.
Try it in your Observability dashboard.
The Vercel Firewall now supports using an OR operator to link condition groups within a custom WAF rule.
Previously, customers could only use an AND operator to join condition groups. This update now supports AND or OR , allowing customers to create more complex WAF actions.
Learn more about the Vercel Firewall or navigate to your Firewall tab to customize rules.
Fluid compute is Vercel’s next-generation compute model designed to handle modern workloads with real-time scaling, cost efficiency, and minimal overhead. Traditional serverless architectures optimize for fast execution, but struggle with requests that spend significant time waiting on external models or APIs, leading to wasted compute.
To address these inefficiencies, Fluid compute dynamically adjusts to traffic demands, reusing existing resources before provisioning new ones. At the center of Fluid is Vercel Functions router, which orchestrates function execution to minimize cold starts, maximize concurrency, and optimize resource usage. It dynamically routes invocations to pre-warmed or active instances, ensuring low-latency execution.
By efficiently managing compute allocation, the router prevents unnecessary cold starts and scales capacity only when needed. Let's look at how it intelligently manages function execution.
Sitecore—a leading digital experience platform—wanted to create a transformative AI tool that would help marketers connect more deeply with their brand assets, driving both consistency and creativity. Using the AI SDK, they lunched Sitecore Stream—a dynamic, AI-powered brand assistant that empowers marketers to interact with their brand content in visually interactive and conversational way.
Vercel now supports pnpm v10.
New projects with a pnpm-lock.yaml file with lockfileVersion: '9.0' will automatically use pnpm v10 for Install and Build Commands. Existing projects will continue to use pnpm v9 for backwards compatibility, since pnpm v9 also uses lockfileVersion: '9.0'.
Check your build logs to see which version a deployment uses. If you'd like to manually upgrade or downgrade your version, use Corepack.
Visit the package managers documentation to learn more.
System bypass rules allow Pro and Enterprise customers to configure firewall rules to skip Vercel system mitigations, including DDoS protection, for specific IPs and CIDR ranges. Although we strongly recommend against disabling protections, customers—particularly ones that deploy a proxy in front of Vercel—may experience traffic issues that can be mitigated by deploying system bypass rules.
Improvements to the system bypass rules give customers additional control over how the rules are deployed, including:
Expanded support beyond production domains to preview domains
Added support for single domain rules for preview deployment URLs and aliases
Expanded project-scoped bypass rules to include all domains connected to a project
Increased limits for system bypass rules for Pro to 25 and Enterprise to 100 (from 3 and 5 respectively)
Learn more about the Vercel Firewall.
External rewrites between projects within the same team now use Fast Data Transfer only for the destination request. This change makes Fast Data Transfer for the original request free.
Commonly used as a reverse proxy or for microfrontend architectures, rewrites can be configured in vercel.json, middleware, or next.config.ts to route requests between the same or separate Vercel projects without changing the URL shown to the user.
Usage for external rewrites to the same team:
Fast Data Transfer for the original and destination request have been optimized and consolidated into a single stream, reducing overall transfer.
Each external rewrite triggers a full request lifecycle, including routing and Web Application Firewall checks, ensuring security policies are enforced per project, and counts as a separate Edge Request.
Learn about rewrites and monitor your Fast Data Transfer usage and observability.
The Vercel Marketplace now has an Experimentation category to allow developers to work with feature flagging and experimentation providers in Vercel projects.
Statsig—a modern feature management, experimentation, and analytics platform—is now available as a first-party integration in this new category, so users can:
Connect Statsig with your Vercel projects directly from the Vercel Marketplace
Leverage integrated billing through Vercel
Sync your Statsig experiments into Edge Config for ultra-low latency
Manage and roll out features progressively, run A/B tests, and track real-time results
Additionally, you can use the Flags SDK to load experiments and flags from Statsig using the newly released @flags-sdk/statsig provider.
Explore the template or get started with Statsig on the Vercel Marketplace, available to users on all plans.
The Vercel Firewall dashboard now displays enriched IP address data, including the autonomous system (AS) name, AS number (ASN), and geolocation on hover.
This information helps identify the origin of an attack, determine the owner of an IP address, and create targeted custom rules to block malicious traffic.
Learn more about the Vercel Firewall.
Middleware support for the Node.js runtime is now available, providing full Node.js support for authentication, personalization, and more—using familiar APIs.
Middleware continues to be deployed globally on Vercel, regardless of the runtime used. We are first releasing support for Node.js Middleware in Next.js 15.2.
This experimental feature requires the Next.js canary channel. Upgrade to next@canary and enable the nodejs experimental flag in your config to use it:
You must also specify the Node.js runtime in your middleware file:
Deploy now with Next.js 15.2.
Vercel now supports glob patterns (like testing-*) in the git.deploymentEnabled field, giving you more control over branch deployments.
Previously, you could disable deployments for specific branches by explicitly naming them. Now, you can use patterns to match multiple branches at once.
For example, the configuration below prevents deployments on Vercel if the branch begins with internal-.
Learn more about Git configuration.
We’ve updated our list of supported Top-Level Domains (TLDs) registrations, adding new options and removing select ones as we refine our domain offerings.
Newly supported TLD registrations We now support 66 additional TLDs, including:
- Generic domains (e.g. .page, .food, and .hosting)
- Professional domains like (e.g. .lawyer, .phd, and .inc)
- Lifestyle domains (e.g. .beauty, .living, and .lifestyle)
- Interest-based domains (e.g. .guitars, .yachts, and .watches)
TLD registrations no longer supported We have removed registration support for select TLDs, including:
- Various country-code TLDs (ccTLDs, e.g. .at, .lu, .ma)
- Regional TLDs (e.g. .berlin, .wales, .istanbul)
- Multiple compound TLDs (e.g. .com.co, .org.pl, .co.nz)
Future plans for TLD registration support
We’re continuing to improve our domain offerings by:
Enhancing support for country-code TLDs (ccTLDs), with plans to reintroduce select options.
Expanding our portfolio with additional generic TLDs (gTLDs).
These changes take effect immediately. Existing registrations, renewals, and services for deprecated TLDs remain unaffected.

Every second, Vercel blocks attacks before they reach your applications—keeping businesses online and developers focused on shipping, not security incidents.
Vercel’s security capabilities combine real-time DDoS mitigation, a powerful Web Application Firewall (WAF), and seamless SIEM integrations to provide always-on protection without added complexity.
Here’s what happened in the last quarter.
We’ve simplified the Project Settings page, bringing all build customization options under a unified Builds and Deployment section.
Vercel framework-defined infrastructure automatically detects settings for many frontend frameworks, but you can still customize build options to fit your needs.
Learn more about project settings and how to configure a build.
The new @vercel/related-projects package helps sync deployment information across separate Vercel projects, ensuring your applications always reference the latest preview or production deployment URLs without manual updates or environment variable changes.
Previously, developers had to manually enter deployment URLs, manage connection strings, or use environment variables to keep the projects communicating effectively. Now, this data is automatically available and updated at both build and runtime.
For example, a monorepo containing:
A frontend Next.js project that fetches data from an API
An backend Express.js API project that serves the data
Related Projects can now ensure that each preview deployment of the frontend automatically references the corresponding preview deployment of the backend, avoiding the need for hardcoded values when testing changes that span both projects.
Related Projects are linked using a Vercel project ID. You can find your project ID in the project Settings page in the Vercel dashboard.
Learn more about linking related projects.
The Flags SDK—our open source library for using feature flags in Next.js and SvelteKit applications—is now available under the new package name flags.
The new name signals our commitment to open source and the independence of the package from any specific entity or platform. Our framework-first approach of the SDK aims to simplify usage, avoid client-side flag evaluation, and improve user experience by eliminating layout shifts.
We are working on adapters with partners like Statsig, Optimizely, and LaunchDarkly to ensure a seamless integration with the Flags SDK.
Until now, each provider established their own approach to using feature flags in frameworks like Next.js, which led to duplicate efforts across the industry and drift in implementations. Going forward, the Flags SDK will help all feature flag and experimentation providers benefit from its tight integration to frameworks, while retaining their unique capabilities.
If you are using @vercel/flags, make sure you are updating to version 3.1.1 and switch your imports and package.json to flags.
Learn more in our redesigned documentation and examples.
The Vercel Firewall overview page now shows improved visibility into your traffic and the Firewall status. Navigate to your Firewall page to see:

Marketplace integration providers can now register integration actions for deployments, allowing for automated resource-side tasks such as database branching, environment variable overrides, and readiness checks.
When a user deploys a project that has connected Marketplace integration with configured actions, the deployment will pause and wait for all integration actions to complete successfully. This ensures that the deployed resources are properly set up before the deployment proceeds. Users will also receive helpful suggestions within the integration about which actions are available and should be executed.
Learn more about integration actions.
Observability's Vercel Functions dashboard now shows quick-view tiles with key metrics, such as:
Active compute model, like Fluid compute, which enhances efficiency, minimizes cold starts, and optimizes performance
Compute saved with Fluid compute enabled
Average memory usage for your functions
P75 Time to First Byte (TTFB) for performance monitoring
Cold start frequency to track optimization impact
These insights are available for all plans.
Learn more about Observability and Fluid compute.
We’ve optimized our Image Optimization infrastructure, including:
60% faster transformations
New, opt-in reduced pricing
Previously, usage was measured by the number of unique source images ($5 per 1K source images). You can now opt into usage based on transformations with regional pricing, starting from:
Image Transformations: $0.05 per 1K image transformations
Image Cache Reads: $0.40 per 1M cache read units
Image Cache Writes: $4.00 per 1M cache write units
This new pricing model is opt-in through your project settings.
There are no changes to existing customers using Image Optimization
New projects for existing customers will also have no changes
New customers will start on the new pricing today
Pro and self-serve Enterprise customers can view the projected cost difference when enabling in settings. All Enterprise customers can also reach out to their account team to discuss new pricing.
Hobby customers have been moved to the new model's included allotments.
Learn more about Image Optimization pricing.
You can now share deployments with external collaborators. Previously, invitations, access requests, and shareable links were limited to the preview URL for a branch or custom aliases.
The share modal—accessible by selecting Share on a deployment page or from the Vercel Toolbar menu—now allows sharing the specific deployment you are on or the always up-to-date preview URL for the branch.
Read more about sharing deployments.
Vercel now supports Domain Connect, an open standard that simplifies DNS configuration. With one click, you can set up your domain without manually copying DNS records—saving time and reducing errors.
Cloudflare-managed domains are now supported with more providers coming soon.
To get started: Add a new domain to your Vercel project, and Vercel will detect if your domain qualifies for setup through Domain Connect, prompting you to proceed automatically or configure it manually.
We're also implementing Domain Connect as a DNS provider, enabling external services to configure Vercel Domains just as easily.
Learn more about Vercel domains.
Vercel now supports React Router v7 applications when used as a framework:
This includes support for server-rendered React Router applications using Vercel's Fluid compute. Further, the Vercel preset intelligently splits application bundles across Vercel Functions, and supports custom server entry points.
Deploy React Router to Vercel or learn more about React Router on Vercel.
Pro and Enterprise plans can now select multiple regions for Vercel Functions directly from the dashboard. This update simplifies configuration by removing the need to define regions in vercel.json.
Multi-region support is available for all Vercel Functions and supports Vercel's implementation of Fluid compute, which encourages a dense global compute model that positions dynamic functions closer to your data.
Visit your project’s Settings tab to customize your regions or learn more about configuring regions for Vercel Functions.
When updating project settings, such as environment variables, Vercel will now automatically prompt you to redeploy.
A toast notification will appear when you change any settings that require a redeploy to take effect. After clicking Redeploy, you can track the progress of your deployment.
Learn more about project settings.
Archive deployments are useful for deploying large projects with thousands of files from the CLI.
We previously released the split-tgz archive deployment as a new archive option: vercel deploy --archive=split-tgz. This new capability offered up to 30% faster uploads and avoided file upload size limits.
We’ve confirmed split-tgz’s stability and made it the default behavior for tgz. This means the separate split-tgz option is now deprecated as the split-tgz functionality and benefits power the default tgz option.
Learn more about CLI archive deployments.
We’ve updated our database starter templates to support selecting any Postgres or Redis provider available in the Vercel Marketplace when deploying.
These templates are now provider-agnostic, allowing developers to seamlessly integrate alternative database and key-value store solutions while maintaining the same developer experience.
Check out the documentation to learn how to deploy your own.
Monitoring now has better firewall support, offering insights into your firewall rules:
Filter blocked requests by actions and custom firewall rules
More fields are now displayed when available:
IP Country
User Agent
Route
Request Path
Region
These metrics are available for all Observability Plus and Monitoring customers.
Monitoring recently became part of Observability Plus.
We optimized the deploy step of the build process to reduce build times by 2.8 seconds at P99, 760ms at P75, and 410ms on average.
For customers with a large number of Vercel Functions (100+), builds are more than 50 seconds faster. Several customers have time savings of over 2 minutes.
Check out the documentation to learn more about builds.
Starting on March 1st, 2025, we will begin the rollout of a new execution duration limit of 300 seconds for Vercel Functions using the Edge runtime.
Previously, Edge Functions had no fixed timeout for streaming responses, leading to unpredictable behavior based on system resources and traffic. With this update, Edge Functions will consistently allow streaming responses for up to 300 seconds, including post-response tasks like waitUntil().
Learn more about Vercel Functions using the Edge runtime.
Project Overview and Deployment Details pages now include a Deployment Configuration section under the deployment card.
Expand to view snapshots of Fluid Compute, Function CPU, Deployment Protection, Skew Protection, and Secure Compute settings.
This section is available for all new deployments moving forward. It will appear on your Project Overview page after your next production deployment.
We've made improvements to Grep, our tool for quick code search.
You can now search across 1,000,000 public git repositories
The app has been rebuilt with Next.js 15, improving performance with Partial Prerendering
Support for dark mode
While dedicated servers provide efficiency and always-on availability, they often lead to over-provisioning, scaling challenges, and operational overhead. Serverless computing improves this with auto-scaling and pay-as-you-go pricing, but can suffer from cold starts and inefficient use of idle time.
It’s time for a new, balanced approach. Fluid compute evolves beyond serverless, trading single-invocation functions for high-performance mini-servers. This model has helped thousands of early adopters maximize resource efficiency, minimize cold starts, and reduce compute costs by up to 85%.
Vercel Functions can now run on Fluid compute, bringing improvements in efficiency, scalability, and cost effectiveness. Fluid is now available for all plans.
Optimized concurrency: Functions can handle multiple requests per instance, reducing idle time and lowering compute costs by up to 85% for high-concurrency workloads
Cold start protection: Fewer cold starts with smarter scaling and pre-warmed instances
Optimized scaling: Functions scale before instances, moving beyond the traditional 1:1 invocation-to-instance model
Extended function lifecycle: Use waitUntil to run background tasks after responding to the client
Runaway cost protection: Detects and stops infinite loops and excessive invocations
Multi-region execution: Requests are routed to the nearest of your selected compute region for better performance
Node.js and Python support: No restrictions on native modules or standard libraries
Enable Fluid today or learn more in our blog and documentation.
On-demand concurrent builds automatically and dynamically scale builds, increasing build capacity and shipping velocity.
Starting today, new projects in Enterprise teams will use on-demand concurrency by default to eliminate build queue bottlenecks. You can turn this feature on for existing projects at any time with urgent on-demand concurrent builds or enable it at the project level.
You are charged for on-demand concurrency based on the number of 10-minute build slots required to allow the builds to proceed as explained in usage and limits.
Check out the documentation to learn more about on-demand concurrent builds .
When Next.js introduced Incremental Static Regeneration (ISR) in 2020, it changed how developers build for the web. ISR combines the speed of static generation with the flexibility of dynamic rendering, enabling sites to update content without requiring full rebuilds.
Vercel has supported ISR from day one, making it easy for teams at The Washington Post, Algolia, and Sonos to serve fresh content while keeping page loads fast.
Incremental Static Regeneration (ISR) enables you to update content in the background without needing to redeploying your application. You can scale CMS or content-backed applications to millions of pages without having slow builds.
We've optimized our infrastructure to make ISR faster and more cost-efficient:
Smaller writes: ISR cache writes are now compressed by default, using fewer ISR write and read units (8KB chunks) per update and lowering Fast Origin Transfer (FOT) costs. Both reads and writes are now compressed.
Region-aware caching: The ISR cache is now available in all regions and automatically aligns with your functions' region. If your project spans multiple regions, the most cost-effective location is chosen automatically. This improves performance, especially for traffic outside North America, and regional pricing applies.
Redeploy your project to apply these updates or learn more about ISR.
Update: The rollout of this change completed on February 5th, 2025 around 8am PST.
Monitoring now includes three new metrics for Edge Functions to provide a comprehensive view of your Edge Function activity and performance:

Following the Node.js 18 end of life on April 30, 2025, we are deprecating Node.js 18 for Builds and Functions on September 1, 2025.
Will my existing deployments be affected?
No, existing deployments with Serverless Functions will not be affected.
When will I no longer be able to use Node.js 18?
On September 1, 2025, Node.js 18 will be disabled in project settings. Existing projects using 18 as the version for Functions will display an error when a new deployment is created.
How can I upgrade my Node.js version?
You can configure your Node.js version in project settings or through the engines field in package.json.
How can I see which of my projects are affected?
You can see which of your projects are affected by this deprecation with:
The archive option was introduced for CLI deployments hitting rate limits like the limit on the maximum amount of files. Prebuilt deployments commonly use archive uploads as they generate thousands of files at build time.
Previously, archive deployments were always compressed into one large file with the only existing --archive option, tgz. Deployments using tgz may hit the file size upload limit. Additionally, uploading one large archive file is slower than uploading multiple file parts.
The beta split-tgz format resolves these issues by splitting large archives into smaller parts. split-tgz avoids the static file upload limit and uploads large prebuilt projects up to 30% faster.
Example usage: vercel deploy --archive=split-tgz
Learn more about CLI deployments.
Audit logs are now generally available for Enterprise customers, and can be integrated with SIEMs for real-time export.
Audit logs provide an auditable trail of key events and changes within your Vercel team. With an immutable record, you can track who performed an action, what was done, and when—with access to up to 90 days of historical data.
Enterprise customers can also configure a real-time audit log stream to their existing Security Information and Event Management (SIEM) tools, such as Datadog or Splunk. Additionally, logs can be sent to durable object storage solutions like Amazon S3, Google Cloud Storage, or a custom HTTP POST endpoint.

Python is now supported in the ongoing in-function concurrency public beta.
In-function concurrency optimizes functions to handle multiple invocations simultaneously, improving resource efficiency. By reusing active instances instead of creating new ones, it reduces idle compute time and associated costs.
In-function concurrency is particularly beneficial for workloads with external API or database calls, such as AI models, where functions often sit idle while waiting for responses.
The in-function concurrency public beta is available to Pro and Enterprise customers using Standard or Performance Function CPU, and can be enabled through your dashboard. Real-time tracking of resource savings is available in Observability.
Learn more in our blog post and documentation, or get started with our template by enabling In-function concurrency in your project settings.
Logs now indicate when Vercel Functions reach (or near) their maximum duration or memory allocation for each request.
Logs also include quick links to configure function maximum duration, CPU & memory, region, and Node.js Version directly from requests.
View your project's logs.
Dates across the dashboard now provide more precision.
For the first three days, dates are displayed as relative (e.g. "10m ago")
After three days, they switch to absolute values (e.g. "Jan 3")
This builds on a recent update where hovering over dates reveals more information, including the exact timestamp.
With v0, Vercel's AI-powered pair programmer, anyone can participate in prototyping, building on the web, or expressing new ideas.

For ecommerce teams running Salesforce Commerce Cloud, the platform's monolithic design can feel like a double-edged sword. While its out-of-the-box capabilities promise rapid deployments, they often hinder frontend flexibility and innovation. But what if you could unlock a new level of performance—without risking your core business?
That’s exactly what a global sportswear brand achieved. Their headless Salesforce migration strategy halved their load times, cut cart abandonment by 28%, and increased mobile conversion rates by 15%. All without a disruptive, big-bang migration.
Here’s how they did it and how you can too.
The "Contain Types" filter in runtime logs has been replaced by two new filters for better clarity:
Resource: Filters which infrastructure resource within the Vercel Edge Network was used to serve the request. Examples include Serverless Functions, Edge Cache, and Edge Middleware
Request Type: Filters which framework-defined mechanism or rendering strategy was used by the request. Examples include API routes, Incremental Static Regeneration (ISR), and cron jobs
These updates provide more granular insights into how your requests are processed. Both filters are available on all plans starting today.
Learn more about how Vercel processes requests.
You can now view your Speed Insights traffic broken down by project in the Usage tab.

Pro and Enterprise customers can now configure firewall rules to bypass system mitigations, including DDoS protection, for specific IPs and CIDR ranges.
We strongly recommend against bypassing protections. However, if you feel like the protections are blocking legitimate traffic, this feature presents a break-glass option. This may be particularly applicable if you have a proxy in front of Vercel that provides DDoS protection and which may interfere with Vercel's protection.
To configure system bypass rules:
Navigate to the Firewall in the Vercel dashboard
Click Configure at the top right to access the configuration page
Use the System Bypass Rules section at the bottom to specify the IP address or CIDR range to bypass mitigations for your production domains
Pro customers can set up to 3 bypass rules and Enterprise customers can set up to 5.
Learn more about Vercel Firewall's automatic DDoS mitigation.
In our previous blog post, we introduced Hive, the internal codename for Vercel’s low-level compute platform, powering all of our builds. However, some builds come with unique security requirements. For these, Hive integrates seamlessly with Vercel's Secure Compute, which enables teams to securely connect with their backends through private connections without compromising performance.
Since moving Secure Compute to Hive, provisioning times have dropped from 90 seconds to 5 seconds and build performance has improved by an average of 30%, delivering both speed and reliability for even the most sensitive workloads.
AI crawlers have become a significant presence on the web. OpenAI's GPTBot generated 569 million requests across Vercel's network in the past month, while Anthropic's Claude followed with 370 million. For perspective, this combined volume represents about 20% of Googlebot's 4.5 billion requests during the same period.
After analyzing how Googlebot handles JavaScript rendering with MERJ, we turned our attention to these AI assistants. Our new data reveals how Open AI’s ChatGPT, Anthropic’s Claude, and other AI tools crawl and process web content.
We uncovered clear patterns in how these crawlers handle JavaScript, prioritize content types, and navigate the web, which directly impact how AI tools understand and interact with modern web applications.
Every 100ms of latency can cost ecommerce applications up to 8% in sales conversion. At scale, this can cost millions in revenue.

Read our Node.js runtime documentation to learn more.
Streaming is now supported and will soon be enabled by default in Vercel Functions for the Python runtime, allowing functions to send data to the client as it’s generated rather than waiting for the full response. This is particularly useful for AI applications.
This change will be rolled out progressively. Starting today, it will apply to all new projects and will take effect for all existing projects on January 5, 2025. On this date, projects using Log Drains will be migrated, and streaming responses will impact the format and frequency of runtime logs.
To enable streaming as the default for your Vercel Functions using Python, add the VERCEL_FORCE_PYTHON_STREAMING=1 environment variable in your project. Streaming will then be enabled on your next production deployment.
For more information, read the Python streaming documentation or get started with our template.
Vercel’s framework-defined infrastructure provisions cloud resources while providing full transparency, from the initial build to every incoming request. Developers can track how static assets are distributed globally, functions handle ISR revalidation, and resources manage routing, server-side rendering, and more.
As users visit your app, granular metrics reveal which resources were leveraged to serve their request. This series unpacks the Vercel Edge Network and associated resource allocation, exploring each stage of a request, and how Vercel streamlines the process.
With a clear understanding of these metrics and optimization strategies, you can deliver better user experiences while improving resource consumption and reducing costs.
Pro customers can now set up to three regions for their Vercel Functions, enabling compute to run closer to distributed data sources for faster responses and improved performance. When multiple Vercel Function regions are configured, user requests that require compute will be routed to the closest specified region.
Previously, functions for Pro customers were restricted to a single region. Increasing to three regions enables:
Global low-latency
Maintaining high compute density leading to higher cache hit rates and lower cold starts
Compatibility with standard database replication like Postgres read replicas
This also adds an extra layer of redundancy, complementing the built-in multi-Availability Zone redundancy of Vercel Functions.
To configure additional regions, add a regions property to your vercel.json.
Redeploy your project for the changes to take effect. Learn more about configuring regions.
Vercel Blob can now track file upload progress, enabling for a better user experience when uploading files.
With the latest @vercel/blob package, you can use the new onUploadProgress callback to display progress during file uploads. In the Dashboard, you'll also see the upload progress for your files.
Skew Protection eliminates version differences between web clients and servers—available for Pro and Enterprise customers. Starting today, new projects will have Skew Protection enabled by default.
Existing projects will not be changed, however you can manually enable Skew Protection in the project's settings.
Skew Protection ensures client-side code matches the server-side code for the corresponding deployment for a period of time or until a hard page refresh. This protects from version mismatch errors when creating a new deployment, such as file name changes from hashed bundles or even post backs from Server Actions.
Learn more about Skew Protection.

Whether you're serving billions of users or building your first project, the Frontend Cloud helps you remove friction from the development and delivery process. This allows you to focus on building your product instead of managing and configuring the infrastructure required to make it work.
Provisioning time for Vercel Secure Compute builds has decreased from 1-2 minutes to under 5 seconds—a 20x speed improvement.
These builds require provisioning of build containers with custom configurations for each customer’s security needs. Now, this tailored container-generation process is significantly faster, reducing overall deployment times.
Additionally, builds are consolidated closer to the Secure Compute regions such as Frankfurt, Sao Paulo, Oregon, N. Virginia, Sydney, or Ireland, enhancing efficiency even further.
Learn more about Vercel Secure Compute.
MotorTrend—a Warner Bros. Discovery company and the world’s leading media company on all things automotive—needed a digital experience as powerful as the vehicles they showcase. Bogged down by a legacy tech stack, their development team faced frustratingly long build times and a cumbersome release process. They knew a complete redesign wasn't the answer—they needed a platform upgrade.
The Next.js AI Chatbot template has been updated to use Next.js 15, React 19, and the Auth.js for Next beta.
The template's UI has also been redesigned to include a model switcher to make it easier for users to experiment with different models. The new side-by-side UI keeps your users' output and chat messages on screen simultaneously.
Users in the limited beta of Observability can now get additional metrics related to builds, including:
Build time: Understand your build time across time, identifying changes to longer build times faster.
Memory and disk usage: See how effective your builds are by viewing your average memory and disk usage.
Build steps: Explore P50 and P90 durations of each build step.
Observability is in limited beta for current Monitoring users and can be accessed from the new Observability tab in your Vercel projects.
When major political developments unfold, millions rush to news websites, putting immense pressure on digital infrastructure. With global audiences, slow-loading websites or crashes during a major event can be catastrophic for a news organization.
Vercel has a new low-level untrusted and ephemeral compute platform—designed to give us the control needed to securely and efficiently manage and run builds. Since November 2023, this compute platform, internally codenamed "Hive", has powered Vercel’s builds, enabling key improvements like enhanced build machines and a 30% improvement in build performance.
The platform operates on the fundamental assumption that we’re executing potentially malicious code on multi-tenant machines, requiring it to be safe, reliable, performant, and cost-effective. It’s architected to handle multiple use cases and can be composed in different ways depending on what’s needed. Most recently, Hive allowed us to reduce provisioning times for Secure Compute customers from 90 seconds to 5 seconds, while also improving their build speeds.
We built Hive because we needed finer control and more granular management to continuously improve Vercel’s infrastructure, to meet the growing demands of our customers and to fulfill our vision of delivering the best development experience in the world.
We've improved the experience of deploying projects using pnpm, Corepack, and Turborepo together.
Previously, combinations of these tools could result in unexpected behavior or complex build errors. Clear error and warning messages have been added, explaining how to fix problems when incompatibilities exist.
For example, a project with Corepack enabled, specifying pnpm@9.0.0, and a lockfile of version 6.0 would previously see the warning: Ignoring not compatible lockfile. Now, this is handled with a clearer error message: Detected lockfile "6.0" which is not compatible with the intended corepack package manager "pnpm@9.0.0". Update your lockfile or change to a compatible corepack version.
Additionally, each package previously had to define its own packageManager. The root package.json#packageManager is now detected in monorepo projects with Corepack enabled and applied to all packages.
Users in the limited beta of Observability can now view advanced insights for serverless Vercel Functions. Explore low level metrics about function execution, including:
CPU throttle and memory usage: Understand CPU usage and memory consumption and see if you could benefit from upgrading the function to more resources
Time to First Byte (TTFB): See how quickly your function responds to requests by sending the first bytes of the response
Function start type: View cold start and pre-warmed function invocation rates
Observability is in limited beta for current Monitoring users and can be accessed from the new Observability tab in your Vercel projects.
You can now filter by custom date ranges in Speed Insights. Select any custom time period in the date range picker, or drag across the graph to quickly focus on specific period.

Our fifth annual Next.js Conf finished yesterday, where we shared our research and upcoming improvements to the framework, as well as what's new in the community and Next.js ecosystem. Over 1,000 people in the Next.js community gathered in San Francisco and tens of thousands around the world watched online to see what's new with Next.js.
With its compiler-first approach, fine-grained reactivity, and ability to integrate with any JavaScript project, Svelte stands apart from other frameworks.
At Vercel, we're big fans of Svelte—deeply invested in its success and constantly working to make our platform the best place to build and deploy Svelte apps.
With the arrival of Svelte 5, let's explore what makes this release exciting.
v0 is a powerful tool for generating high-quality UIs and code, and it's also an educational asset for designing and creating on the web. It leverages deep integrations with libraries and modern frameworks like Next.js and React. Whether you're looking to scaffold a new project, fetch data, or create 3D graphics, v0 is designed to meet all your frontend development needs.
To get the highest quality generations, you need to be able to craft input prompts to guide v0 well. The better you guide v0 and understand its strengths, the more accurate and relevant the responses you'll get.
In this post, we’ll look at how you can get the most out of v0’s core features, UI generation abilities, code generation, and developer support.
Vercel's OpenID Connect (OIDC) Federation is now generally available. Strengthen your security by replacing long-lived environment variable credentials with short-lived, RSA-signed JWTs for builds and Vercel Functions.
Use Vercel’s OIDC Identity Provider (IdP) to issue tokens for cloud providers and services like AWS, Azure, Firebase, and Salesforce.
With general availability, we are also introducing a new Team Issuer mode, which mints OIDC tokens with a URL unique to your team. This allows you to configure your cloud environment with stricter zero trust configurations.
To enable Vercel OIDC, update your project's security settings and integrate it using the @vercel/functions package. If you're already using Vercel OIDC, we recommend opting into Team Issuer mode in those settings.

The prestigious BNP Paribas Open, held annually in Indian Wells, California, attracts top tennis talent and a global audience. To match its world-class status, the tournament required a significant digital upgrade, enabling dynamic, real-time tracking and engagement with hundreds of players for their fanbase of millions.
Vercel's main website, once a single large Next.js application, serves both our website visitors and logged-in dashboard. But, as Vercel grew, this setup revealed opportunities for improvement. Build times grew, dependency management became more intricate, and workflows needed optimization. Minor changes triggered full builds, affecting isolated development and CI pipelines.
It was clear a change was needed.
Since IP addresses can be considered personal information under certain data privacy laws, we're giving you the ability to configure whether Vercel forwards IP addresses to your Log Drains. Now, similar to Monitoring, you can disable this forwarding in the security settings of your Team.
This can be done by Owner and Admin roles on Pro and Enterprise plans.
Upstash has joined the Vercel Marketplace with three of its core products: KV, Vector, and QStash. These services offer integrated billing, automated account provisioning, and direct access to the Upstash console from directly within the Vercel Dashboard.
This integration replaces Vercel KV, and in the coming months, we will begin a zero-downtime migration for all existing stores with no action required and no change in price.
Existing Vercel KV users will continue to have full access to their current stores without any changes during the transition, and new stores can be created via the Upstash Marketplace Integration.
Get started with the Vercel Marketplace, available to customers on all plans.
AI changes how we build software. In combination with developers, it creates a positive feedback loop where we can achieve better results faster.
However, traditional testing methods don't work well with AI's unpredictable nature. As we've been building AI products at Vercel, including v0, we've needed a new approach: eval-driven development.
This article explores the ins and outs of evals and their positive impact on AI-native development.
Last October we introduced v0—a generative user interface system powered by natural language and AI. Users generated over four million designs, creating everything from sophisticated dashboards to polished marketing pages.
Now, v0 is like having an expert programmer sitting next to you. It's an assistant that specializes in web technologies and frameworks to help you generate functional code and UI from best practices, migrate or debug existing code, or learn to code for the first time.
Starting today, v0 is available to teams of all sizes, with plans designed to help you collaborate and scale securely. v0 Team and v0 Enterprise plans offer security features like SSO and, for Enterprise, the ability to opt out of data training, while helping you share and reuse knowledge and generations across your whole team.
We recently introduced the ability to manage deployment retention—a way to automatically clean up your project's deployments after a set period of time.
Starting November 18, 2024, we are changing the default retention policy for canceled deployments only. Canceled deployments will be automatically deleted after 30 days for all projects, unless your project has a custom deployment retention setting. There will be no impact to deployments that are not canceled.
Learn more about Deployment Retention.
We've improved how Vercel Authentication handles rewrites between protected deployments. If you have access to the deployment and it belongs to the same team as the original deployment, we now automatically grant access to the rewritten deployment.
Previously, when rewriting to a protected deployment, Vercel Authentication would redirect through vercel.com to authenticate the user, causing the rewrite to become a redirect.
Automatic access between protected rewrites is only applicable if you are already authenticated with Vercel on the original deployment. This new behavior does not apply to rewrites when you authenticate using Shareable Links, Protection Bypass for Automation, or Password Protection.
Read more about Deployment Protection in our docs.
React Three Fiber (R3F) is a powerful React renderer for three.js that simplifies building 3D graphics using React's component-based architecture. Whether you're building complex environments, animations, or interactive scenes, R3F makes it accessible—even if you're not an expert at math or physics.
With R3F support in v0, our AI-powered development assistant, you can incorporate 3D designs in your projects by chatting with v0 using natural language. Let's explore how to use v0 and R3F to create interactive 3D scenes to elevate your web designs.
Emburse manages travel and expense for over 12 million users in 120 countries. They were operating a legacy stack and needed to modernize, so they partnered with Rangle, a leading digital transformation consultancy and Vercel Expert.
Together with Rangle, Emburse implemented Vercel, Next.js, and Sanity, significantly improving the site’s performance and speed while addressing key concerns for their marketing team.
When you make a commit to a monorepo, the Recent Previews section on your team overview page will now show an expandable row containing preview, source, and deployment links for all deployments triggered by your commit, across all projects.

ChatPRD is an AI co-pilot designed for product managers, enabling them to write product requirements documents, brainstorm roadmaps, and improve overall efficiency around product work. As a solo founder, Claire Vo built ChatPRD from the ground up. In just nine months, the platform has garnered 20,000 users and is now focusing on expanding its features to support team collaboration.
Central to this rapid growth and development has been the AI SDK on Vercel.
Chatbase helps companies build chat-based AI agents that are trained on their data to chat with users and perform tasks. It handles customer support, sales, lead generation, and more.
From the beginning, they prioritized building a platform that could move fast in the competitive market. To achieve this, they chose Vercel and Next.js as the tech stack for their app and marketing website, along with Vercel's AI SDK, which enabled them to quickly iterate and deliver AI-driven features.
By prioritizing iteration speed, Chatbase grew to 500K monthly visitors and $4M ARR in 1.5 years. Vercel's developer experience (DX) allows the team to focus on innovation, not infrastructure. The AI SDK enables rapid implementation of custom chats and model optimizations.
The Supabase integration on the Vercel Marketplace provided a frictionless onboarding experience, ensuring zero loss in fidelity or developer experience. Developers can easily set up and manage Supabase databases directly from the Vercel CLI or dashboard
Since the launch, Supabase has seen a notable increase in new signups, as the Marketplace has become their largest partner channel. Based on Supabase’s increased business and early success, we’re excited for what’s next and the future of Vercel Marketplace.
In the world of crypto, market surges and unexpected events create unpredictable traffic spikes, like Gunna wearing a diamond-encrusted Ledger at the Met Gala.
For Ledger—a leading provider of hardware wallets—capturing this no-notice interest becomes crucial for Ledger’s online presence, which may see traffic fluctuate from 1-5 million users monthly. Navigating the dynamism of the crypto market requires a technical infrastructure as resilient and secure as Ledger’s hardware products.

We’re sharing a first look at a new version of Vercel Functions with support for in-function concurrency that brings the best of servers to serverless functions.
We’ve been testing this new version with customers and are seeing a 20%-50% reduction in compute usage and respective cost reduction without latency impact.
It’s a serverless product optimized specifically for interactive workloads such as server-rendering of web pages, APIs, and AI applications. Vercel Functions continue to offer native Node.js support with accelerated cold-start performance based on V8 bytecode and instance pre-warming for production workloads.
In-function concurrency is now in public beta, and allows a single function instance to handle multiple invocations concurrently, improving resource utilization by taking advantage of idle time in existing function instances.
Traditionally, serverless architecture maps one function instance to a single invocation. With in-function concurrency, overlapping invocations can increase efficiency by 20%-50%, reducing gigabyte-hours and lowering costs.
As part of the beta, we’re limiting the number of concurrent invocations per instance, and will be gradually increasing the limit based on feedback. Note, this capability may increase latency for purely CPU-bound workloads.
In-function concurrency public beta is available for all Pro and Enterprise customers using Standard or Performance Function CPU, you can enable it through your dashboard and track resource savings in real time.
Read our blog post and documentation for more information.
At Vercel Ship, we introduced the new Web Application Firewall (WAF), an application-layer firewall that complements our platform-wide firewall. This enables our customers to implement custom or managed rulesets, such as protection against the OWASP Top 10 risks.
Since its release, Vercel’s WAF has blocked billions of malicious requests, demonstrating its resilience and reliability across a wide variety of use cases, from small startups to large enterprise deployments.
We're beginning to roll out new Observability capabilities which will give enhanced insights into your application's performance and behavior in the Vercel dashboard.
This will provide detailed analytics across functions, data transfer, caching, and API requests to bring further observability to Vercel's framework-defined infrastructure.
New insights include:
Vercel Functions and external API requests: Monitor function behavior and external requests, including invocations, durations, and error rates
Vercel Edge Network: Track data transfer, ISR usage, and edge requests with detailed insights into cache success, revalidations, and geo-based performance
Observability is now in limited beta for current Monitoring customers and can be accessed from the new Observability tab in your Vercel projects.
For advanced platform observability, explore our integrations with Sentry, Datadog, Honeycomb, and more.
Vercel Web Application Firewall (WAF) rate limiting is now generally available, giving you precise control over request volumes to your applications.
With over 15 parameters, including target path, headers, method, and cookies, you can define the business logic for rate limiting. Then, apply a rate-limiting algorithm tied to IP, JA4 digest, headers, or user agent to control the frequency of matching traffic within your set limits.
When paired with persistent actions, rate limiting can help reduce resource abuse across Edge Requests, Middleware, Data Transfer, and Function execution.
Rate limiting with a fixed-window algorithm is available today for Pro customers, with an additional token-bucket algorithm available to Enterprise customers. Pricing for rate limiting is regional starting at $.50 per 1 million allowed requests.
Add rate limiting using a template or read the rate limiting documentation to learn more.
Vercel Web Application Firewall (WAF) now supports persistent actions to block repeat offenders who trigger firewall rules.
These persistent actions enforce specific responses—such as blocking—against clients for a defined period, ranging from 1-60 minutes. While active, these actions prevent unnecessary processing by blocking requests earlier in their lifecycle, reducing edge request load.
You can apply persistence to existing rules for actions like deny, challenge, and rate-limiting, adding an extra layer of control to your firewall logic.
Learn more about persistent actions.
Streaming is now enabled by default for all Vercel Functions running on Node.js for Pro and Enterprise teams, marking the final step in the plan we published on July 8th, 2024. This means Vercel Functions can now send data to the client as it’s generated, instead of waiting for the entire response.
The VERCEL_FORCE_NODEJS_STREAMING environment variable is no longer required—streaming is now applied automatically upon deployment.
Logging changes: Streaming responses will alter the format and frequency of your runtime logs. If you are using Log Drains, check that your ingestion pipeline can process the new log format and increased log frequency.
Read our blog post and documentation for more information.
High-performing web teams focus on innovation, not infrastructure. Vercel's framework-defined infrastructure accelerates developer velocity, allowing teams to build faster and more efficiently.

This update simplifies network management and enhances secure, self-service connections between Vercel and AWS environments. Check out the documentation to learn more.
In any given week, Vercel Firewall blocks around 1 billion suspicious TCP connections, with some days seeing upwards of 7 billion malicious HTTP requests. Vercel's platform is designed to automatically mitigate DDoS attacks, blocking thousands of these threats every day to keep your site secure and operational without user intervention. Vercel is built to minimize disruptions and safeguard your resources from unnecessary costs by serving only legitimate traffic.
Web apps today are judged on six core principles: speed, global presence, scalability, dynamism, reliability, and security. Users and businesses now expect excellence in all six categories, making them non-negotiable.
As user experiences have become more engaging and dynamic, the limitations of Content Delivery Networks (CDNs) and Infrastructure as Code (IaC)—once the industry standards for application delivery—are becoming increasingly apparent.
CDNs, designed for static content, fail to meet the demands of modern, interactive and real-time web applications. At the same time, while IaC enables programmatic management, its use for web applications often leads to building undifferentiated tooling and systems rather than dedicating those resources to more bespoke, complex infrastructure challenges.
These technologies have not kept pace with the evolving web, leading to an emerging and compelling solution: frontend clouds that abstract away complex infrastructure, enabling next-generation content, experiences, and application delivery. This shift allows developers to focus on what truly matters—innovating to enhance web applications, drive business value, and delight users.
We have made a number of improvements to ensure the Vercel Toolbar is there when you need it but stays out of the way when you don't:
Shrinks when inactive: The shrunken toolbar shows the comment, share (or flags), and menu icons. The full toolbar will show on hover. You can turn off shrinking in the toolbar menu under Preferences.
No Longer Shows Avatars: We removed the avatars of team members who viewed the deployment. This reduces visual noise and quiets the toolbar's presence in the network tab.
Normal Text Selection: The toolbar no longer adds its own highlight or opens the thread editor when text is selected. It shows a small comment indicator which can be clicked to start drafting a comment on the selected text.
To quickly toggle the toolbar you can use ⌘ + . on MacOS or Ctrl + . on Windows. You can also drag it to a different side of your page, and it will remember to spawn there next time.
See the documentation for more information about the Vercel Toolbar.
You can now install integrations from the Vercel Marketplace directly through the Vercel CLI.
The Vercel Marketplace offers native integrations that allow you to use provider products —currently Supabase, Redis, and EdgeDB—directly from the Vercel dashboard without leaving the platform or creating separate accounts.

As publishers of leading independent games, the team at Devolver is never short on work. But as a small engineering team, they felt limited by their clunky infrastructure and were spending more time on system management than they needed. With Vercel, the Devolver team was able to cut time spent on system management and configuration by more than half, allowing them to bring game websites to life 73% faster. Soon after adopting Vercel, the team was even able to launch five websites during a 30-minute press conference without any issues.
We recently introduced bytecode caching—an experimental feature built on our new Rust-based core for Vercel Functions—designed to drastically reduce start times during increasingly rare cold starts. Even when cold starts do occur, their impact is now minimal and barely noticeable.
After validating the stability and performance improvements of bytecode caching, the feature is now stable and the default for all Node.js 20+ Vercel Functions.
This change reduces global cold start times by up to 60%, exceeding our initial benchmarks and observations. The improvement is particularly significant for functions that load a large amount of JavaScript, with smaller functions experiencing less impact.
Bytecode caching is automatically enabled for all functions running on Node.js 20 and using CommonJS (e.g., Next.js). Additionally, we're working to extend this support to include ESM for broader compatibility. Learn more in our blog post.
You can now visualize Runtime Logs with a time series chart.
Observe the distribution of info, warning, and error logs over time
Analyze and understand your application's behavior more effectively

Recently, there was an issue affecting our customers when trying to purchase a domain containing non-English characters. This problem became apparent when these domain purchases consistently failed, creating a significant roadblock for users wanting to expand their online presence with internationalized domain names (IDNs).
In today's AI-driven landscape, your business's competitive edge lies in how effectively you integrate AI into your product and workflows.
This guide focuses on three critical aspects of building scalable AI applications:
On August 7, 2024, Vercel's Edge Middleware and Edge Functions experienced a significant outage affecting many customers. We sincerely apologize for the service disruption.
Vercel’s platform is designed to minimize the risk of global downtime. As standard practice, we use staggered rollouts for both code and configuration changes. Every aspect of our infrastructure is designed to gracefully fail over to the next available region in the event of an incident, and ensures no single point of failure across infrastructure components. However, on Wednesday, an upstream provider for a subset of our compute infrastructure went into a globally erroneous configuration state.
This event tested our infrastructure's resilience and how we respond to a global provider failure. Let’s break down what happened, how we responded, and the steps we’re taking to eliminate this as a possible failure mode.
The Vercel AI SDK is a toolkit for building AI applications with JavaScript and TypeScript. Its unified API allows you to use any language model and provides powerful UI integrations into leading web frameworks such as Next.js and Svelte.

We've revamped the Account Settings with a new, intuitive navigation structure by breaking down into three different sections - Overview, Activity, and Settings.
The Overview page now offers a quick snapshot of your teams and domains, including the option to request access to teams you're not part of.
The Activity page presents a chronological list of events for the last 12 months.
The Settings page consolidates all user-specific options, including authentication, billing, and access tokens.
This streamlined layout aims to enhance clarity and simplify account management for all users.
Beyond Menu is a popular food delivery service in the US that connects restaurants and diners. Their Next.js app is deployed on Vercel and serves millions of hungry visitors every month.
To scale their development, they decided to adopt feature flags for gradual rollouts, instant rollbacks, A/B testing, trunk-based development and easier collaboration both internally and with beta users.
They knew they needed to evaluate feature flags and A/B tests on both the server and the client. And since they used the App Router, the solution needed to work with React Server Components, Client Components and different rendering modes like static, dynamic and partial prerendering.
At Beyond Menu, every millisecond impacts conversion, so they turned to Vercel's Edge Config and Hypertune for seamless feature flag management without layout shifts.
Understanding how search engines crawl, render, and index web pages is crucial for optimizing sites for search engines. Over the years, as search engines like Google change their processes, it’s tough to keep track of what works and doesn’t—especially with client-side JavaScript.
The Vercel Toolbar now loads up to 10x faster and uses hardware acceleration for smoother interactions. The toolbar has features like comments and feature flags, and developer tools like the interaction timing tool for optimizing INP.
You can also now toggle toolbar visibility based on the environment (preview or production) for your team or project from the dashboard. This is under the "Vercel Toolbar" section in general settings
When the toolbar is on, individual users can still hide and unhide it using the keyboard shortcut ⌘ + . (Mac) or Ctrl + . (Windows), or disable it for their session with the option in the toolbar menu (☰).
Learn more about toolbar settings and functionality.
You can now deploy FastHTML Python projects on Vercel with zero configuration.
FastHTML is a new next-generation web framework for fast, scalable web applications with minimal, compact code. It builds on top of popular foundations like ASGI and HTMX. You can now deploy FastHTML with Vercel CLI or by pushing new changes to your git repository.
Deploy the FastHTML template or run vercel init fasthtml in your terminal to get started.
We recently introduced a new Flags SDK that allows using feature flags, in Next.js and SvelteKit, and works with any feature flag provider—or when using no flag provider at all. It's not meant to be a competitor to other feature flag providers. Instead, it’s a tool that sits between your application and the source of your flags, helping you follow best practices for using feature flags and experiments, keeping your website fast.
Follow along below to get started with the Flags SDK, beginning with a simple feature flag to more sophisticated cases, discussing tradeoffs along the way.
With over $1B in revenue flowing through their digital properties, Elkjøp (Elgiganten), Nordic subsidiary of Currys PLC and leading consumer electronics retailer in the region, knew their digital presence needed to reflect their in-store commitment to innovation and excellence. Their previous ecommerce platform, built on Angular and self-hosted on Kubernetes, had become a source of frustration for both customers and internal teams. Slow page loads, SEO struggles, and inefficient developer experience were impacting the bottom line and hindering their ability to deliver the exceptional online shopping experience their customers deserved.
You can now redirect requests to a new page using custom Firewall rules, adding to the existing challenge and block actions.
Publishing custom rules does not require a new deployment and will instantly propagate across the global Vercel Edge Network. Therefore, using custom rule redirects in moderation could provide a fast alternative to Edge Network redirects, particularly in emergency situations.
Firewall redirects execute before Edge Network configuration redirects (e.g. vercel.json or next.config.js) are evaluated.
Custom rules are available for free on all plans.
Vercel CLI v35 introduces new commands to access of deployment and runtime logs:
vercel deploy --logs deploys and shows build logs
vercel inspect --logs shows build logs for an existing deployment
vercel logs now follows runtime logs of an existing deployment
You can now use the --json option to stream logs as JSON. This makes it easier to parse and filter logs using tools like jq.
To use these features, update to the latest version of the Vercel CLI:
Turbopack is a new JavaScript/TypeScript bundler we’ve been cooking at Vercel. Building on 10+ years of learnings from webpack, we want to build a bundler that can be used with many frameworks.
We’re moving the Turbopack codebase into the Next.js repository—and wanted to share an update on our progress with Turbopack so far, as well as where we’re headed.
Web rendering has evolved from simple server-rendered HTML pages to highly interactive and dynamic applications, and there are more ways than ever to present your app to users.
Static Site Generation (SSG), Server-Side Rendering (SSR), Client-Side Rendering (CSR), Incremental Static Regeneration (ISR), and experimental Partial Prerendering (PPR) have all been developed to optimize performance, SEO, and user experience in various situations.
Vercel now automatically skip builds for unchanged code in your monorepo.
Projects without changes in their source code (or the source code of internal dependencies) will be skipped, reducing build queuing and improving the time to deployment for affected projects.
This feature is powered by Turborepo, and works with any monorepo using workspaces. For more advanced customization, like canceling builds based on branches, you can configure an Ignored Build Step.
Learn more about skipping unaffected projects.

We've improved our Edge Network performance by increasing the initial TCP congestion window by 300%. This enhancement allows sending more data in the initial and subsequent round-trips, resulting in faster page loads for websites of all sizes.
End users will experience significant speed improvements when first loading any site hosted on Vercel, with many sites seeing up to 3x faster initial page loads. The larger initial congestion window allows data transfer to ramp up more quickly, reaching higher speeds in fewer round-trips. This optimization is particularly beneficial for high-latency connections, such as those on mobile devices.
This performance upgrade is available immediately for all Vercel customers across all plans, with no action required. Your sites will automatically benefit from these improvements without any changes needed on your part.
We’ve improved Fast Origin Transfer—our Edge Network’s ability to transfer data from every region globally to the origin—to be compressed by default.
Fast Origin Transfer is incurred when using any of Vercel’s compute projects, like Functions, Middleware, and Incremental Static Regeneration (ISR). Starting today, all data transfer between edge regions and the origin location is now automatically compressed. This matches the behavior of Fast Data Transfer.
Learn more about Fast Origin Transfer and how to optimize.
You can now drain Vercel Firewall actions to external providers through Log Drains.
Requests denied by the Vercel Firewall will be drained with the firewall source. This includes the following events:
Requests blocked by a Custom Rule
Requests blocked by Challenge Mode
Requests blocked Managed Rules (e.g. OWASP CRS)
Requests blocked by an IP Rule
If a rule is set to log or to bypass, requests will not be sent to Log Drains. Firewall actions are also surfaced inside of Monitoring.
Learn more about the Log Drains.
The Vercel Firewall now localizes the challenge page text to 22 different languages.
Challenges are automatically served for malicious traffic or when defined through custom rules. The updated page also features a new design, which supports light and dark mode.
Learn more about the Vercel Firewall.
Vercel now supports OpenID Connect (OIDC) Federation, enabling you to enhance your security by replacing long-lived environment variable credentials with short-lived, RSA-signed JWTs for external requests in both builds and Vercel Functions.
You can now leverage Vercel's OIDC Identity Provider (IdP) to issue persistent tokens for cloud providers such as AWS, Azure, GCP, and more.
Enable OIDC in your project's security settings and leverage the @vercel/functions package for integration with third-party providers, like this:
Learn more about OpenID Connect Federation in the documentation.
Runtime logs now have improved filtering and visibility of request details:
Query Params Visibility: View query parameters for each request directly in the UI.
Request ID Filtering: Filter logs by request ID using the new filter icon next to each ID.
These improvements are available to all Vercel customers.
Vercel Functions run code in response to user traffic without the need to manage your own infrastructure, provision servers, or manage hardware.
In 2023, Vercel Functions added support for streaming HTTP responses.
This feature has been enabled for frameworks like Next.js (App Router), SvelteKit, Remix, and more. We've been progressively rolling out streaming to more frameworks over the past two years, and we're beginning to roll out streaming for all functions and compatible frameworks.
Vite-based frameworks such as SvelteKit, Remix, Nuxt, or Astro can now more easily integrate with the Vercel Toolbar in both local and production environments. The Toolbar enables you to comment on deployments, toggle feature flags, view draft content from a CMS, and more.
The updated @vercel/toolbar package offers a Vite plugin and client-side function for injection and configuration, and can be integrated like this:
Check out the documentation to learn more.
Streaming will soon be enabled by default for all Node.js Vercel Functions.
This change will be effective for Hobby accounts starting July 8th, 2024; and for Pro and Enterprise accounts starting October 1st, 2024.
To enable streaming as the default immediately for all your Vercel Functions, set the VERCEL_FORCE_NODEJS_STREAMING environment variable in your project to true. Streaming will be enabled on your next deployment.
Streaming responses from functions will change the format and frequency of your runtime logs. If you are using Log Drains, you should ensure that your ingestion pipeline can handle the new format and increased frequency.
Check out this blog post and our streaming documentation for more details.
Get notified after a deployment promotion by subscribing to the new deployment.promoted event through a webhook.
A promotion is the act of assigning your production domains to a deployment, so it starts serving your production traffic. This new event will notify you when:
Deployments are automatically promoted and domains are assigned (default)
Deployments are explicitly promoted from the CLI, API, or Dashboard.
Learn more about promotions or see the full list of events.
Vercel is extending its newly introduced approach to working with feature flags to SvelteKit, with the v2.6.0 release of @vercel/flags.
With @vercel/flags/sveltekit you can now implement feature flags in your SvelteKit application code and call them within functions. Using this pattern automatically respects overrides set by the Vercel Toolbar, and integrates with our Developer Experience Platform features like Web Analytics and Runtime Logs.
Learn more about Vercel feature flags with SvelteKit in our documentation and deploy your own SvelteKit app with feature flags here.
The UI for inspecting your deployment source and build output files is improved. Use the deployment Source tab to see what goes into a deployment and what gets created from the build process.
Based on your feedback, Spend Management now pauses production deployments by default when your set amount is reached.
Spend Management allows you to receive notifications, trigger a webhook, and pause projects when metered usage exceeds the set amount within the current billing cycle. This stops you incurring further cost from the production deployments.
You'll receive realtime notifications when your spending approaches and exceeds the set amount. For further control, you can continue to use a webhook in addition to automatic project pausing
This includes Web and Email notifications at 50%, 75%, and 100%. You can also receive SMS notifications when your spending reaches 100%
Hobby customers will have their projects automatically paused when reaching the included free tier limits and do not need Spend Management
Check out our documentation to learn more.
Vercel customers making API requests to OpenAI from Functions in Hong Kong (hkg1) may have received an email from OpenAI identifying API traffic from a region that OpenAI does not currently support.
OpenAI will take additional steps to block API traffic from unsupported countries and territories on July 9. We understand this block will include Functions in the Hong Kong region on Vercel. While the majority of functions do not execute in this region, Edge Functions may require updates to the execution region.
You can prevent this change affecting your deployments by specifying allowed regions for your functions and excluding Hong Kong. Changing regions requires a redeployment of your application.
Learn more about OpenAI's supported regions.
We've improved the performance and experience of the Vercel Blob file browser:

This feature is available to all customers using Speed Insights.
You can now export Web Analytics data as CSV. The aggregated data includes information about unique visitors and page views for the selected data set.
This feature is available to all customers using Web Analytics.
To give users more clarity on the domains owned across both Teams and accounts, Team Owners can now see account-owned domains in the same tab as their Team domains. This change provides more visibility into the domains you own across your Teams and account.
Learn more about domains on Vercel in the documentation.
Vercel's infrastructure now keeps a minimum of one function instance warm for production environments on paid plans. This improves startup times for apps with relatively low traffic.
This builds on our recent improvements to make Vercel Functions start up even faster, by powering them with Rust and adding support for bytecode caching.
Get started with Vercel Functions.
You can now more easily run end-to-end tests against deployments protected by Vercel Authentication.
All plans can now create a secret value to bypass authentication, which can then be set as an HTTP header (or query parameter) named x-vercel-protection-bypass.
The automation bypass enables you to protect your project's deployments with Vercel Authentication while still providing access to external services like Checkly and Playwright for your CI/CD e2e testing.
We've achieved certification under the DPF to further strengthen our commitment to privacy at Vercel.

Mintlify, a platform for public documentation, is a toolkit for developers to write, maintain and host documentation. The platform offers a flexible solution that can be used out of the box or customized to fit specific needs, enabling developers to create help guides, tutorials, and API references.
We recently shipped a new Rust-based core for Vercel Functions to improve startup times.
Today, we are announcing a new experimental feature to further reduce startup latency for large applications, resulting in up to 27% faster cold starts.
Vercel Ship 2024 was all about the power of the frontend cloud, highlighting the integrations, ecosystem, and teams building the web's best products.
In any given week, Vercel blocks around 1 billion suspicious TCP connections, with some days seeing upwards of 7 billion malicious requests. The Vercel Firewall has been silently mitigating DDoS and Layer 3/4 attacks, but it's been operating as a black box with limited transparency.
Feature flags help teams to release with confidence, safely roll out changes, and test efficiently, improving collaboration and accelerating development cycles. If you use tools like LaunchDarkly, Statsig, Split, or Optimizely to create feature flags, we're making integrating them into your Vercel workflows as easy as possible.
Vercel’s Frontend Cloud is all about giving you and your team the tools to prioritize the user experience—so you can focus on what makes your product great and quickly iterate together with your team.
Vercel Log Drains are now generally available—send runtime and build logs from Vercel to third-party services.
What’s new?
Since we introduced Log Drains, you can now filter by different environments, define a sampling rate, transport logs with either the JSON or NDJSON formats, and more.
New Usage Based Billing
Usage of Log Drains costs $10 per 5GB of data transfer; all logs sent to a third-party accrue Log Drain usage automatically.
Existing Pro customers have three additional months free before billing begins. You can view the exact date based on your billing cycle in the dashboard.
Log Drains are only available on Pro and Enterprise plans. Existing Hobby customers may continue to use Log Drains as configured, but no further usage or configuration is available.
How can I check my Log Drain usage?
You can view your existing Log Drain usage on the Usage page.
You can now get the toolbar in your production environment without any configuration by installing the Vercel Chrome Extension and ensuring that you are signed in to your team on Vercel.com. You can also enable the toolbar for your production domains by selecting Enable Vercel Toolbar in Production in the toolbar menu and choosing the domain you'd like to enable it on. For more advanced usage, it is still possible to use the toolbar's npm package.
This allows you and your team to use all the features of the Vercel Toolbar, like comments, flags, and tools like accessibility audit and interaction timing, in production.
Learn more about the features of the toolbar and adding it to your environments in the documentation.
We’re introducing a new approach for working with feature flags. This approach allows declaring feature flags in code and calling them as functions. Flags implemented using this pattern can automatically respect overrides set by the Vercel Toolbar, and integrate with our Developer Experience Platform features like Web Analytics and Runtime Logs.
The pattern avoids common pitfalls of client-side feature flag and experimentation usage, such as flashing the wrong experiment, loading spinners, layout shift, and jank. It works with any feature flag provider and even custom setups.
The pattern further allows for optionally precomputing certain feature flags in Middleware. Middleware can then route visitors to statically generated pages tailored to their specific combination of feature flags and experiments.
This even works when multiple flags are present on the page, which typically suffers from combinatory explosion. Precomputing is great for experimentation on marketing pages as it allows keeping them completely static with ultra-low TTFB, no layout shift, and no flashing of the wrong experiment.
We have implemented this new feature flags design pattern for Next.js in @vercel/flags/next, and we are releasing an implementation for SvelteKit soon.
Check out our documentation to learn more.
The Vercel DX Platform now has a deep understanding of the feature flags you use and create in third-party providers. This beta integration provides better insights into your applications and streamlines your development workflow.
Web Analytics integration: Break down page views and custom events by feature flags in Web Analytics, gaining granular insights into user interactions.
Enhanced Log visibility: The platform now displays feature flags in logs, making it easier to understand the conditions under which errors occur.
reportValue: Reports an evaluated feature flag from the server for runtime logs and Custom Analytics Events (server-side).
<FlagValues />: Surfaces a feature flags value on the client for usage in Analytics.
These features have universal compatibility with any feature flag provider you're already using, like LaunchDarkly, Statsig, or Split, or custom setups.
This update lets users on all plans leverage existing feature flag workflows within the Vercel platform and ship safely with more confidence.
Check out the documentation to learn more.
Enterprise customers can now protect against the top OWASP risks.
The Vercel Firewall protects against the OWASP Core Ruleset for Enterprise, which enables Vercel to log, block, or challenge traffic against these rules.
In addition to new custom rules, customers can also ensure they remain protected against the biggest risks for web applications with new OWASP Top 10 protection. For example, this ruleset includes automatic protection against SQL injection attacks.
Contact sales to see a demo and learn more.
The Vercel Firewall now allows you to create custom rules to log, block, challenge, or rate limit (beta) traffic. The Firewall is available on all plans for free.
You can define custom rules to handle incoming traffic:
Rules can be based on 15+ fields including request path, user agent, IP address, JA4 fingerprint, geolocation, HTTP headers, and even target path.
Firewall configuration changes propagate within 300ms globally. If you make a mistake, you can instantly rollback to previous rules.
You can now see requests automatically protected by the Firewall, as well as managed custom rules for the WAF. You can also access managed rulesets, included our first ruleset available for Enterprise to mitigate the OWASP core risks.
Learn more about the WAF and available configuration options. Contact us if you want to try our private beta for rate limiting.
Accessibility Audit now runs in the background for you everywhere you have the Vercel Toolbar. You can view the compliance of Web Content Accessibility Guidelines 2.0 level A and AA rules for the page you are on from the toolbar menu. The rules will show grouped by impact as defined by deque axe.
You can also turn on recording to keep track of issues that turn up as you move around a page. This feature is available to all Vercel users.
See the Accessibility Audit documentation to learn more.
The OPTIONS Allowlist improves the security of deployments on Vercel by limiting CORS preflight OPTIONS requests to specified paths.
Before the OPTIONS Allowlist, all OPTIONS requests to deployments bypassed Deployment Protection in compliance with CORS specifications.
The new OPTIONS Allowlist feature is available on all plans.
Learn more about the OPTIONS Allowlist.
The Vercel Toolbar now helps you investigate your site's Interaction to Next Paint (INP).
This new Core Web Vital, which impacts Google search ranking as of March 2024, is now available in the toolbar menu under Interaction Timing. As you interact with your site, this tool measures input delay, processing times, and rendering delay and allows you to inspect in detail how these are affecting each interaction's latency.
This tool can also notify you as you navigate your site of any interactions that take more than 200ms, the upper limit for a good INP score. These toasts can be configured in Preferences under the toolbar menu.
Learn more about the Vercel Toolbar and INP.
The Vercel Toolbar can now show a preview of how the page will look shared on social media.
After selecting "Open Graph" from the toolbar menu, you can see how your images and metadata will display on X, Slack, Facebook, and LinkedIn. The toolbar also provides information if any metadata is missing on your page, which could affect the display of social cards.
Learn more about the Vercel Toolbar.
You can now select an aggregation when analyzing data in Vercel Monitoring. This change provides more visibility to make it easier to analyze your application.
The following new aggregations are now available, in addition to sums and counts.
Average values
Per second sums and counts
Minimum and maximum values
75th, 90th, 95th and 99th percentiles
Percentages of the overall values
These aggregations can be used with any visualize setting, for analyzing data transfer, function duration, function execution, and request counts. Enterprise customers can also access data with a five minute granularity when viewing 24 hours of data or less.
Learn more in our documentation about Monitoring.
Modern Next.js applications can have large codebases operating across multiple environments, including client components running in the browser, Server Actions executing on the server, and more.
You can now use waitUntil by importing @vercel/functions in your Vercel Functions, regardless of the framework or runtime you use.
The waitUntil() method enqueues an asynchronous task to be performed during the lifecycle of the request. It doesn't block the response, but should complete before shutting down the function.
It's used to run anything that can be done after the response is sent, such as logging, sending analytics, or updating a cache, without blocking the response from being sent.
The package is supported in Next.js (including Server Actions), Vercel CLI, and other frameworks, and can be used with the Node.js and Edge runtimes.
Learn more in the documentation.
The merger of two of the world's largest affordable art providers, Desenio and The Poster Store, gave their developers the chance to modernize their application architecture, improve their entire process, and dismantle the monolithic approach that made for long deployment times and slow iteration. Thanks to Vercel, they went from duplicate pipelines to a unified workflow—resulting in faster builds, a 37% lower bounce rate, 48% longer sessions, and a 34% improvement in site conversions.
Imagine a customer finding the perfect item on your website in seconds—not because they know the jargon to search, but because your search bar understands what they're looking for.
That level of convenience wasn't possible a year ago. Even getting close was a huge hassle. But now, thanks to advancements in AI and large language models (LLMs) like OpenAI’s GPT, Google’s Gemini, and Anthropic’s Claude, businesses without dedicated AI teams are rolling out impressive features in record time.
And Vercel is here to help speed that process up. Let’s take a look at what’s possible.
Based on your feedback, Hobby customers can now run functions up to 60 seconds.
Starting today, all new deployments will be able to increase the maximum duration of functions on the free tier from 10 seconds up to 60 seconds. If you need longer than 60 seconds, you can upgrade to Pro for up to 5 minutes.
Check out our documentation to learn more.
Enterprise customers can now manage access to critical Vercel projects across many Vercel users easier than ever with Access Groups.
Access Groups allow team administrators to create a mapping between team members and groups of Vercel projects. Users added to an Access Group will automatically be assigned access to the Projects connected to that Access Group, and will be given the default role of that group, making onboarding easier and faster than ever for new Vercel Team members.
For customers who use a third-party Identity Provider, such as Okta, Access Groups can automatically sync with their provider, making it faster to start importing users to Vercel without creating manual user group mappings (Vercel is SCIM compliant).
For example, you can have a Marketing Engineering Access Group, which has a default project role of "Developer". When a new member is added to the Marketing Engineering group, they will automatically be assigned the Developer role, and access to all Projects assigned to that group.
This builds on our advanced access controls, like project level access controls and deployment protection. Learn more about Access Groups or contact us for a demo of our access security features.
You can now recommend feature flag overrides for specific branches in order to equip your team and quickly share work in development.
The Vercel Toolbar will suggest flag overrides to team members working on the branch locally or when visiting a branch Preview Deployment. This extends the recently announced ability to view and override your application's feature flags from Vercel Toolbar, currently in beta.
As part of this change, we’ve improved the onboarding for setting up and integrating feature flags into the toolbar.
Learn more about the Vercel Toolbar and feature flags.
Starting today, new Python Builds and Functions will use version 3.12 and new Ruby Builds and Functions will use version 3.3.
If you need to continue using Python 3.9 or Ruby 3.2, ensure you have 18.x selected for the Node.js Version in your project settings to use the older build image.
For Python 3.9, ensure your Pipfile and corresponding Pipfile.lock have python_version set to 3.9 exactly. Similarly, for Ruby 3.2, make sure ruby "~> 3.2.x" is defined in the Gemfile.
Check out the documentation to learn more about our supported runtimes.
Vercel Functions run code on demand without the need to manage your own infrastructure, provision servers, or upgrade hardware—and are now powered by Rust under the hood.
Today, we're releasing the AI SDK 3.1, with ModelFusion joining our team.
This release brings us one step closer to delivering a complete TypeScript framework for building AI applications. It is organized into three main parts:
Vercel is committed to providing a secure and reliable platform for hosting websites and applications—across all industries. But this can be challenging with industry-specific regulations, especially for healthcare organizations and entities that process protected health information (PHI).
You can now add multiple email addresses to your Vercel account.
For example, both your personal email and work email can be attached to the same Vercel account. All verified emails attached to your account can be used to login. You can mark an email as "primary" on your account, which makes it the destination for account and project notifications.
Learn more in our documentation.
We've optimized our build process to reduce upload times by 15% on average for all customers.
For customers with large builds (10,000 outputs or more), upload times have decreased by 50%. This results in a time saving of up to 5 minutes per build for several customers.
Learn more about builds in our documentation.
This is a reminder for legacy secrets deprecation. On May 1st, 2024 secrets will be automatically converted to sensitive Environment Variables for Preview and Production environments. Secrets attached to Development environments will not be migrated.
Existing legacy secrets will be automatically converted. You do not need to manually take action for non-development values. Read below to view your impacted projects.
All Environment Variables remain securely encrypted. The majority of Vercel workloads have moved from the legacy secrets functionality.
Why are legacy secrets being sunset?
Our legacy secrets were encrypted values global for your entire team and could only be managed through the CLI. Based on your feedback, we have since:
Made all Environment Variables encrypted by default
Added Sensitive Environment Variables to prevent values from being decrypted by users
Added Shared Environment Variables to reuse truly global values across teams
When will I no longer be able to use secrets?
On May 1st, 2024, secrets will be removed from Vercel CLI:
Existing secrets added to the Preview and Production environments will be converted to Sensitive Environment Variables
Existing secrets added to the Development environment will not be migrated for your security. If you have a secret shared between all environments, including Development, it will not be migrated. These values must be manually migrated.
How can I migrate to Sensitive Environment Variables?
Secrets for Preview and Production environments will be automatically migrated.
For secrets which contain the Development environment, you should create new Sensitive Environment Variables, as these values will not be automatically migrated for your security. If you need to share Environment Variables across projects, you can make them shared.
How can I understand if I’m affected?
To list projects using secrets that will be automatically converted, run:
The Vercel Terraform Provider allows you to create, manage and update your Vercel projects, configuration, and settings through infrastructure-as-code.
You can now control significantly more Vercel resources through Terraform:
Control whether custom production domains are automatically assigned
Enable and disable Git LFS on a project
Configure Automatic Function Failover
Allow the prioritization of production builds over preview builds
Configure Skew Protection
Create and manage Deploy Hooks
Enable and disable Comments on preview deployments
Enable and disable Git Comments for a project
Set up and manage Configurable Log Drains
Create and manage Account Webhooks
Configure Edge Config stores, schemas and access tokens.
Learn how to get started with the Terraform provider for Vercel. If you already have Terraform set up, upgrade by running:
Tonies, creators of the smart audio system for children, sought to expand into new markets, but it became clear that their existing platform couldn't support this growth. In response, they undertook a strategic transition to a new frontend platform powered by Vercel's Frontend Cloud and Contentful's CMS.
The default CPU for Vercel Functions will change from Basic (0.6 vCPU/1GB Memory) to Standard (1 vCPU/1.7GB Memory) for new projects created after May 6th, 2024. Existing projects will remain unchanged unless manually updated.
This change helps ensure consistent function performance and faster startup times. Depending on your function code size, this may reduce cold starts by a few hundred milliseconds.
While increasing the function CPU can increase costs for the same duration, it can also make functions execute faster. If functions execute faster, you incur less overall function duration usage. This is especially important if your function runs CPU-intensive tasks.
This change will be applied to all paid plan customers (Pro and Enterprise), no action required.

Earlier this month, we announced our improved infrastructure pricing, which is active for new customers starting today.
Billing for existing customers begins between June 25 and July 24. For more details, please reference the email with next steps sent to your account. Existing Enterprise contracts are unaffected.
Our previous combined metrics (bandwidth and functions) are now more granular, and have reduced base prices. These new metrics can be viewed and optimized from our improved Usage page.
These pricing improvements build on recent platform features to help automatically prevent runaway spend, including hard spend limits, recursion protection, improved function defaults, Attack Challenge Mode, and more.
It’s now easier to join a team on Vercel. New team members no longer need to re-enter their email, or create a Hobby team or Pro trial. Team invite emails now lead to a sign up page customized for the team. This includes simplified sign up options that reflect the team's SSO settings.
You can invite new team members under "Members" in your team settings. Learn more about managing team members in the documentation.
Web page load times and responsiveness to user action in web apps is a primary driver of user satisfaction–and both are often dominated by network latency.
Latency itself is a function of the user's connection to the internet (Wifi, LTE, 5G), how far away the server is that the user is connecting to, and the quality of the network in between.
While the latency numbers may seem low by themselves, they compound quickly. For example, a network waterfall of depth 3 on a 300ms link leads to a total latency of 900ms. Technologies like React Server Components can move network waterfalls to the server where the same request pattern might be 100 times as fast.
Global Retail Brands (GRB) is one of Australia’s fastest-growing retailers, specializing in homeware and kitchenware goods with over 250 physical stores throughout the country. GRB is known for its flagship brands such as House, MyHouse, House Bed & Bath, Baccarat, and Robins Kitchen.
Important: This change does not impact customers currently using custom certificates issued by commercial CAs and using them on Vercel via the custom certificate feature.
Vercel uses Let's Encrypt as its certificate authority (CA) to auto-provision TLS certificates to enable secure connections by default. When using custom domains in your Vercel app, traffic between clients and Vercel Edge Network is encrypted and protected using the auto-provisioned Let's Encrypt certificate.
As planned, on September 30th, 2024, the current Let’s Encrypt cross-sign DST Root CA X3 root certificate issued by IdenTrust will expire and no longer be available. Considering the small proportion of internet users with older devices today, Let's Encrypt has decided to officially sunset this cross-sign certificate chain. This change has been planned by Let's Encrypt over the past few years, under their mission of providing safe and secure communication to everyone who uses the Web. You can read more about this change in their blog post.
After September 30th, 2024, clients accessing your websites hosted on Vercel must be able to trust the latest ISRG Root X1 root certificate from their local trust store. Modern operating systems and browsers trust this certificate, and it should not cause any noticeable impacts on your users. However, some older devices, such as Android 7.0 or earlier, may be unable to trust the new chain by default.
You can check more details about this change and review remedy options in our public announcement on the GitHub community forum.
In this post, we’ll look at how we made the dropping lanyard for the Vercel Ship 2024 site, diving into the inspiration, tech stack, and code behind the finished product.
Blue-green deployments are a great way to mitigate the risks associated with rolling out new software versions.

Teleport, an open-core platform for secure infrastructure access, sought to unify and enhance their website and documentation. They needed a framework that could support dynamic content, provide a smooth developer experience, and ultimately provide a robust and up-to-date resource for their customers.
The Gemini AI Chatbot template is a streaming-enabled, Generative UI starter application. It's built with the Vercel AI SDK, Next.js App Router, and React Server Components & Server Actions.
This template features persistent chat history, rate limiting to prevent abuse, session storage, user authentication, and more.
The Gemini model used is models/gemini-1.0-pro-001, however, the Vercel AI SDK enables exploring an LLM provider (like OpenAI, Anthropic, Cohere, Hugging Face, or using LangChain) with just a few lines of code.
Imagine you have a great idea for an AI-powered feature that will transform your ecommerce storefront—but your existing platform stands in the way of innovating and shipping. Legacy platforms come with slow and costly updates, and you're beholden to your vendor's roadmap.
With composable architecture, that all changes. You can choose and seamlessly integrate all the best tools, shipping your ideas with maximum efficiency.
At Vercel, we believe composable should include AI. We want it to be as straightforward as possible within the JavaScript ecosystem to develop AI features that enrich your users’ digital experiences.
Ecommerce brands today face immense pressure to stay agile and innovate continuously. Recognizing the need to optimize site performance, enhance SEO, boost conversions, and improve developer experience, Ruggable, a leading online rug retailer, embarked on a digital transformation with Vercel and Contentful.
Based on your feedback, we're updating how we measure and charge for usage of our infrastructure products.
You can now inspect and filter hostnames in Vercel Web Analytics.
Domain insights: Analyze traffic by specific domains. This is beneficial for per-country domains, or for building multi-tenant applications.
Advanced filtering: Apply filters based on hostnames to view page views and custom events per domain.
This feature is available to all Web Analytics customers.
Learn more in our documentation about filtering.
Design Engineer is a new role that is gaining popularity—a role that is both confusing and exciting. Expectations for what good software looks and feels like have never been higher. Design Engineers are a core part in exceeding that expectation.
Node.js 20 is now fully supported for Builds and Vercel Functions. You can select 20.x in the Node.js Version section on the General page in the Project Settings. The default version for new projects is now Node.js 20.
Node.js 20 offers improved performance and introduces new core APIs to reduce the dependency on third-party libraries in your project.
The exact version used by Vercel is 20.11.1 and will automatically update minor and patch releases. Therefore, only the major version (20.x) is guaranteed.
Read the documentation for more.
The growth in popularity of AI applications, and the relative high cost of the LLMs to power those calls, means AI apps have emerged as an incredibly high-value target for bots and bad actors.
Last year, we introduced Vercel's industry-first Skew Protection mechanism and we're happy to announce it is now generally available.
Skew Protection solves two problems with frontend applications:
If users try to request assets (like CSS or JavaScript files) in the middle of a deployment, Skew Protection enables truly zero-downtime rollouts and ensures those requests resolve successfully.
Outdated clients are able to call the correct API endpoints (or React Server Actions) when new server code is published from the latest deployment.
Since the initial release of Skew Protection, we have made the following improvements:
Skew Protection can now be managed through UI in the advanced Project Settings
Pro customers now default to 12 hours of protection
Enterprise customers can get up to 7 days of protection
Skew Protection is now supported in SvelteKit (v5.2.0 of the Vercel adapter), previously supported in Next.js (stable in v14.1.4), and more frameworks soon. Framework authors can view a reference implementation here.
Learn more in the documentation to get started with Skew Protection.
The Next.js AI Chatbot template has been updated to use AI SDK 3.0 with React Server Components.
We've included Generative UI examples so you can get quickly create rich chat interfaces beyond just plain text. The chatbot has also been upgraded to the latest Next.js App Router and Shadcn UI.
Lastly, we've simplified the default authentication setup by removing the need to create a GitHub OAuth application prior to initial deployment. This will make it faster to deploy and also easier for open source contributors to use Vercel Preview Deployments when they make changes.
Generating more than 4.5 million images a day, Leonardo.ai merges artificial intelligence with creativity to transform content creation across industries like gaming, marketing, and design.
To accelerate the production release process, customers on all plans can now prioritize changes to the Production Environment over Preview Deployments.
With this setting configured, any Production Deployment changes will skip the line of queued Preview Deployments and go to the front of the queue.
You can also increase your build concurrency limits to give you the ability to start multiple builds at once. Additionally, Enterprise customers can also contact sales to purchase enhanced build machines with larger memory and storage.
Check out our documentation to learn more.
You can now configure Function CPU from the project settings page, where you can change your project’s default memory, and by extension CPU. Previously, this could only be changed in vercel.json.
The memory configuration of a function determines how much memory and CPU the function can use while executing. This new UI makes it more clear increasing memory boosts vCPU, which can result in better performance, depending on workload type.
Existing workloads (that have not modified vercel.json) are using the cost-effective basic option. Increasing function CPU increases the cost for the same duration, but may result in a faster function. This faster function may make the change net-neutral (or a price decrease in some cases).
Check out the documentation to learn more.
Pro customers can now automatically pause all projects when a spend amount is reached.
Spend Management allows you to receive notifications, trigger a webhook, and now more immediately pause projects when metered usage exceeds the set amount within the current billing cycle. This stops you incurring further cost from the production deployments.
You'll receive realtime notifications when your spending approaches and exceeds the set amount. For further control, you can continue to use a webhook in addition to automatic project pausing
This includes Web and Email notifications at 50%, 75%, and 100%. You can also receive SMS notifications when your spending reaches 100%

A monolithic ecommerce platform, where your commerce data and user-facing storefront are bundled into one provider, can help you get your business off the ground. But as your customer base expands and your strategies become more sophisticated, you may be bumping into some of the rough edges of your provider.
If you crave blazing-fast site performance, personalized experiences, and the freedom to adapt without vendor lock-in, Vercel and Next.js offer a compelling, composable solution for your storefront’s unlimited global growth.
Here are the benefits composable commerce can offer.
Using feature flags to quickly enable and disable product features is more than just a development technique; it's a philosophy that drives innovation and ensures that only the best, most performant features reach your users.
However, when working on a new feature you need to leave your current browser tab, sign into your flag provider, switch the flag to the value you need for development—all while coordinating and communicating this change with teammates. This adds a lot of overhead and disrupts your work.
Today, we’re making that workflow easier by adding the ability for team members to override your application’s feature flags right from the Vercel Toolbar.
You can manage flags set in any provider including LaunchDarkly, Optimizely, Statsig, Hypertune, or Split—and additionally you can integrate any other provider or even your own custom flag setup. By creating overrides for your flags from the toolbar, you can stay in the flow and improve your iteration speed.
Vercel now supports deploying Remix applications using Vite.
We've collaborated with the Remix team to add Server Bundles to Remix. Vercel will now detect Remix projects using Vite and optimize them using our new Vite preset (@vercel/remix/vite).
This preset enables adding additional features for Remix on Vercel such as:
Streaming SSR: Dynamically stream content with both Node.js and Edge runtimes
API Routes: Easily build your serverless API with Remix and a route loader
Advanced Caching: Use powerful cache headers like stale-while-revalidate
Data Mutations: Run actions inside Vercel Functions
Deploy Remix to Vercel or learn more in the docs.
You can now view and override your application's feature flags from the Vercel Toolbar.
This means you can override flags provided by LaunchDarkly, Optimizely, Statsig, Hypertune, Split, or your custom setup without leaving your Vercel environment.
Vercel can now query an API Route defined in your application to find out about your feature flags, and will pick up their values by scanning the DOM for script tags. From there you can create overrides from the Vercel Toolbar, per session, for shorter feedback loops and improved QA and testing. Additionally, the overrides will be stored in an optionally encrypted cookie so your application can respect them.
This functionality is currently in beta and available to users on all plans.
Check out the documentation to learn more.
If you're a feature flag provider and interested in integrating with the Vercel Toolbar, contact us.
Last October, we launched v0.dev, a generative UI design tool that converts text and image prompts to React UIs and streamlines the design engineering process.
Today, we are open sourcing v0's Generative UI technology with the release of the Vercel AI SDK 3.0. Developers can now move beyond plaintext and markdown chatbots to give LLMs rich, component-based interfaces.
Modern web apps are global, omni-channel and fast. Above all else they must be available at all times. Every second of website downtime translates to lost revenue and eroded customer trust.
Leveraging Vercel's Frontend Cloud allows you to:
Vercel Firewall protects your application from DDoS attacks.
Spikes in high volumes of traffic sometimes indicate malicious activity on your site. Customers can now quickly lock down traffic and further protect against DDoS attacks by challenging requests, minimizing the chance that malicious bots get through.
Attack Challenge Mode is now available for all Vercel customers at no additional cost. When temporarily enabled, all visitors to your site will see a challenge screen before they are allowed through.
Learn how to enable Attack Challenge Mode and protect your site.
In order to prevent issues from reaching production, repositories often have settings enabled to keep the main branch green whenever any code is merged. When there are many developers contributing code, such as in a monorepo, this usually results in a slowdown in developer productivity.
If branches are required to be synced to HEAD before merge, developers may have to update branch multiple times before they can merge their code, unnecessarily performing a lot of the same checks over again. A merge queue is an alternative solution to alleviate this pain, but this can also slow down productivity by forcing commits from each developer to be tested before merge in serial, even from unrelated commits.
With Vercel, you can ensure the safety of production and developers can merge quickly, without using a merge queue.
Vercel’s Frontend Cloud is designed for high availability from the ground up, with robustness against large-scale regional cloud outages at every layer of our architecture.
This includes making it extraordinarily easy for our customers to run the compute they deploy to Vercel in the same highly resilient architecture. Concretely speaking, this can make the difference between downtime or smooth operation during major sales events such as Black Friday.
Vercel and Next.js provide increased observability of your applications through OpenTelemetry.
v1.3.0 of @vercel/otel now providing custom resource and operation names for Datadog to satisfy their cardinality requirements. You can group related URL paths for a given span to reduce cardinality and associated usage.
For example, /products/hoodie can be mapped to /products/[name].
Learn more in our documentation or start using the package with Next.js.
The default Vercel Function timeout of all new projects for Enterprise customers will be reduced to 15 seconds on Feb 20th. This change helps prevent unintentional function usage, unless explicitly opted into the longer function duration (up to 15 minutes).
Existing Enterprise projects will not have their defaults changed.
Check out our documentation to learn more.
We’ve been building a new foundation for compute, built on top of Vercel’s Managed Infrastructure, for the past year.

You can now incorporate AI models and services from industry-leading providers into your Vercel projects with a single click.
AI tab: Seamlessly integrate with 3rd-party AI providers and vector databases.
Playground: In-dashboard playground to explore and experiment with models and preview their outputs.
Check out the documentation to get started.
At Vercel, we strive to provide the best support for ecommerce customers worldwide. As a part of this work, we want to ensure that we provide support for our customers to comply with the Payment Card Industry Data Security Standard (PCI-DSS).
In accordance with Vercel's shared responsibility model, this post will walk you through our recommended approach using an iframe to process payments—creating a secure conduit between your end users and your payment provider.
Preview deployments you have recently viewed or deployed are now accessible from the Recent Previews column on your dashboard.
Each recent preview includes a link to the deployment's page in Vercel and a link to the PR or source on your git provider's site when available.
Learn more in the dashboard overview documentation.
You can now invite emails or team members to view a deployment through the share menu. All invitees will receive an email with a link to the deployment and have access to comment if comments are enabled.
The share menu will display who currently has access to a given deployment. Users with sufficient permissions will also be able to revoke access.
Visit the documentation to learn more about all options for sharing deployments.
You can now add sensitive Environment Variables to your projects for added security of secret values like API keys.
While all Environment Variables are encrypted, sensitive values can only be decrypted during builds. This replaces our legacy secrets implementation which is being sunset.
Get started using Sensitive Environment Variables through the dashboard or with Vercel CLI 33.4.
Legacy secrets are being sunset in favor of Sensitive Environment Variables, which are now shareable across projects.
Existing legacy secrets will be automatically converted. You do not need to manually take action for non-development values. Read below to view your impacted projects.
All Environment Variables remain securely encrypted. The majority of Vercel workloads have moved from the legacy secrets functionality.
On May 1st, 2024 secrets will be automatically converted to sensitive Environment Variables for Preview and Production environments. Secrets attached to Development environments will not be migrated.
Why are legacy secrets being sunset?
Our legacy secrets were encrypted values global for your entire team and could only be managed through the CLI. Based on your feedback, we have since:
Made all Environment Variables encrypted by default
Added Sensitive Environment Variables to prevent values from being decrypted by users
Added Shared Environment Variables to reuse truly global values across teams
When will I no longer be able to use secrets?
On May 1st, 2024, secrets will be removed from Vercel CLI:
Existing secrets added to the Preview and Production environments will be converted to Sensitive Environment Variables
Existing secrets added to the Development environment will not be migrated for your security. If you have a secret shared between all environments, including Development, it will not be migrated. These values must be manually migrated.
How can I migrate to Sensitive Environment Variables?
Secrets for Preview and Production environments will be automatically migrated.
For secrets which contain the Development environment, you should create new Sensitive Environment Variables, as these values will not be automatically migrated for your security. If you need to share Environment Variables across projects, you can make them shared.
How can I understand if I’m affected?
To list projects using secrets that will be automatically converted, run:
Streaming is the key to fast and dynamic web applications.
When streaming, you can progressively send UI from server to client, without needing to wait until all of your data has been loaded. This helps your customers see content immediately, like your main call to action to add an item to the cart.
You can now switch between branches directly from the Vercel Toolbar.
Access the command menu through the toolbar or ⌘K (Ctrl+K on Windows) and select branch switcher. You’ll see your team’s branches sorted to highlight those with recent activity or unread comments. Then, select a branch to switch to that deployment.
Learn more about the command menu and other features of the toolbar.
Vercel and Next.js provide increased observability of your applications through OpenTelemetry.

Next.js
Create React App
Vue.js
Nuxt
Gridsome
Gatsby
SvelteKit
Vite
Learn more about Environment Variables.
Vercel Functions can now automatically failover to the next healthy region.
Vercel's Edge Network is resilient to regional outages by automatically rerouting traffic to static assets. Vercel Functions also have multiple availability zone redundancy by default. We are now enhancing this further with support for multi-region redundancy for Functions.
In the instance of a regional outage, traffic directed towards your Vercel Function using the Node.js runtime will be automatically re-routed to the next healthy region, ensuring continuous service delivery and uptime without manual intervention.
Failover regions are also supported through Vercel Secure Compute, which allows you to create private connections between your databases and other private infrastructure.
You can configure which regions to failover to in your vercel.json file. For example, you might want to fallback to many different regions, or specific regions in a country.
Enterprise teams can enable this feature in their project settings. If you are not on Enterprise, get in touch to upgrade and enable function failover.
Webhooks allow you to get notified through a defined HTTP endpoint about certain deployment or project events that happened on the Vercel platform.
Webhooks are now available for all Pro and Enterprise customers. You can create a maximum of 20 webhooks per account.
Check out our documentation to create your first webhook.
You can now protect your Edge Config with a JSON schema. Use schema protection to prevent unexpected updates that may cause bugs or downtime.
Edge Config is a low latency data store accessed from Vercel Functions or Edge Middleware. It is ideal for storing experimentation data like feature flags and A/B testing cohorts, as well as configuration data for Middleware routing rules like redirects or blocklists.
To protect an Edge Config with a schema:
Select the Storage tab in the dashboard and then create or select your Edge Config
Toggle the Schema button to open the schema editing tab. Enter your JSON schema into the editor, and Vercel will use the schema to validate your data in real-time
Click Save. This will save changes to both the schema and data

Core Web Vitals influence how your application's pages rank on Google. Here, we'll dive into what they are, how they’re measured, and how your users and search ranking are impacted by them.
Viewing domains for your team now has faster search and a refreshed design.
It's now easier to filter domains based on their renewal status, as well as see options to configure, transfer, move, or delete individual domains.
Check out the documentation to learn more.
With the GitHub Issues integration, you can now convert comments to GitHub Issues.
For teams who use GitHub Issues and Projects to track work, this allows comments to fit into your existing workflow. Collect and discuss feedback in-context on your deployment with comments and then convert those threads to issues to manage and track that work.
Your converted issues will contain the full thread, attached images and screenshots, and a link back to the thread within the preview.
GitHub Issues is part of our growing collection of integrations for comments which includes Slack, Linear, and Jira, now available to all Vercel users.
Check out the documentation to learn more.
Vercel Blob now supports storing files up to 5 TB with multipart uploads.
When using multipart: true, put() and upload() will progressively read and chunk data, upload it in parts, and retry if there are issues.
Network output is maximized without consuming too much memory. Multipart uploads support retrying streams (Node.js streams and the Web Streams API), a unique feature amongst file upload APIs.

In 2023, businesses processed more than $18.6 billion on Stripe over Black Friday and Cyber Monday (BFCM).
This year, just 19 days before Black Friday, Stripe asked a question: "What if?" What if they opened up Stripe's core metrics and gave a detailed look into their core business, reliability, and the reach of their products?
In response, employees from across the company came together to construct a real-time, publicly accessible microsite that dynamically showcased Stripe's reliability, transaction volumes, global activity, and more, during BFCM—and they showcased it all on Vercel.
You can now see all outgoing requests for a selected log in Runtime Logs.
Logs now display the status, duration, URL, and a trace for each request. Request metrics work with every request on Vercel, so all frameworks are supported. This makes it easier to debug latency and caching inside your Vercel Functions or when calling databases.
This release also includes various of quality-of-life improvements in the Logs UI.
Request metrics are free while in beta and only available to Pro and Enterprise customers.
You can now use the Pinecone integration to create vector databases for your AI applications. Vector databases enable augmenting LLMs with the ability to retrieve additional knowledge (RAG) from your provided sources.
This integration is available for users on all plans.
Check out the integration to get started.
A security vulnerability in the @clerk/nextjs SDK was identified by the Clerk team recently, which allows malicious actors to act-on-behalf-of other users.
The Clerk team has already released a patch with the latest version. Please check the public announcement by the Clerk team for more details.
While we still recommend updating to the latest version of the Clerk SDK, Vercel has taken proactive measures on our Firewall to protect our customers on all plans.
We will continue efforts to proactively protect Clerk + Next.js deployments on Vercel through the Vercel Firewall, regardless of Clerk's Next.js SDK version running.
You can now use passkeys to login to Vercel including touch, facial recognition, a device password, or a PIN. Passkeys provide a simple and secure authentication option.

Your Vercel personal account will soon automatically become a free team.
What is changing?
Your personal projects will live under a new free team with the slug {username}s-projects.
Future auto-generated deployment URLs will end with {username}s-projects.vercel.app.
Your original username remains unchanged and can be viewed in your account settings.
Existing deployments will not be affected.
Your free Vercel experience will remain unchanged. Upgrading and downgrading will now be easier, as they will no longer require transferring projects.
When will my account be updated?
We'll start rolling out this change today and it might take some time before it's your turn. Once it's your turn, in most cases, update should happen instantly.
For a small number of accounts with thousands of projects or deployments, you may temporarily see a message displayed on the dashboard. During this update period, you will have read access to your personal account projects and resources, but not write access.
Who can I contact if something seems off?
Please contact us using the “Account Management” case type if you have questions about this change or notice something wrong with your account.
After talking to hundreds of developers and looking at thousands of Next.js repositories, I've noticed ten common mistakes when building with the Next.js App Router.
This post will share why these mistakes can happen, how to fix them, and some tips to help you understand the new App Router model.
You can now create HTTPS DNS records in Vercel DNS.
The new HTTPS DNS record type, also known as SVCB or Service Binding record, has recently been published as RFC 9460.
This record type is designed for the HTTP protocol to improve client performance and privacy in establishing secure connections. The record can include additional information about the target server, such as supported ALPN protocols (e.g., HTTP/2, HTTP/3, etc), which can eliminate the need for protocol negotiation/upgrade between client and server to minimize the number of round trips.
Since the HTTPS record type is still a new standard, not all HTTP clients can support it. Learn more in our documentation.
Inefficient developer workflows. Poor user experience. Sluggish site performance. These are common woes that customers come to Vercel to alleviate. They result in costs that affect your team’s day-to-day workflow and impact your organization’s bottom line.
But stakeholders still want to know the answer to a simple question: What will the quantifiable ROI on Vercel be?
Deployment summaries help you understand how changes in your frontend application code lead to managed infrastructure on Vercel. We've improved the output with the following:
Static assets now display a leading / for output paths
Files sizes are now vertically aligned for easier visual scanning
Next.js Metadata outputs are properly categorized under static assets
Partial Prerendering now displays the generated Vercel Functions
Read more in our documentation or learn more about framework-defined infrastructure.
In a large team, creating new code should never be scary. Finding where to place code shouldn't be difficult. And deploying new code certainly shouldn't break anything.
Ideally, your codebase feels transparent: easy to create, adjust, and monitor.
The Frontend Cloud offers a complete Developer Experience (DX) Platform, so you don't have to spend so much developer time curating and maintaining systems that can be easily automated.
Instead, you get centrally-located and collaborative tooling—Git-based workflows with automatic staging environments and more—where you can easily leverage the self-serve tools in front of you that just work by default.
Vercel Firewall protects your application from DDoS attacks and unauthorized access.
Enterprise teams now have increased security with the ability to control traffic and restrict access through static IP addresses or entire network CIDR ranges.
Stay secure by blocking entire subnets, or restricting access from untrusted networks, to prevent attacks against your applications.
Learn more in our documentation or contact our sales team to upgrade to Enterprise.
You can now manage your Vercel Blob files from the dashboard using the new file browser:
View individual files or folders
Upload new files, including support for drag-and-drop and bulk uploads
Delete individual files or in bulk
Recently the Vercel Team had the pleasure of sponsoring AWS re:Invent 2023. This year we attended as an official part of the AWS Marketplace, which makes it possible to onboard and build on Vercel in just a few clicks.
While at re:Invent, I was able to share my thoughts on The Frontend Cloud, Generative UI, and the keys to a highly iterative team. Here’s a look at my talk.
Log Drains now support the following options through the dashboard and API:
Filtering based on environment (production or preview)
Configuring a sample size to reduce the throughput
Learn more in our documentation.
You can now control when domains are assigned to deployments, enabling the manual promotion of production deployments to serve traffic.
When a new deployment is created (with our Git Integrations, CLI, or REST API), Vercel will automatically apply any custom domains configured for the project.
You can now create staged deployments that do not assign domains, which can later be promoted to production and serve traffic. This is helpful for custom workflows and having multiple production environments for QA or testing.
From the dashboard
Disable the assignment of domains for your production branch in your Git project settings.
Find your deployment from the list of all deployments and use the right menu to select Promote to Production.
From the CLI
vercel --prod --skip-domain
vercel promote [deployment-id or url]
Learn more in our documentation.
Instant Rollback enables you to quickly revert to a previous production deployment, making it easier to fix breaking changes.
You can now choose to prevent the automatic assignment of production domains when rolling back. Reverted deployments will not be replaced by new production deployments until you manually promote a new deployment.
Learn more in our documentation.
You can now initiate new deployments directly from the dashboard using a git reference. This approach is helpful when git providers have service interruptions with webhook delivery.
To create a deployment from a git branch or SHA:
From the dashboard, select the project you'd like to create a deployment for.
Select the Deployments tab. Once on the Deployments page, select the Create Deployment button in the three dots to the right of the Deployments header.
Depending on how you would like to deploy, enter the following:
Targeted Deployments: Provide the unique ID (SHA) of a commit to build a deployment based on that specific commit.
Branch-Based Deployments: Provide the full name of a branch when you want to build the most recent changes from that specific branch.
Finally, select Create Deployment and Vercel will build and deploy your commit or branch.
When the same commit appears in multiple branches, Vercel will prompt you to choose the appropriate branch configuration. This choice is crucial as it affects settings like environment variables linked to each branch.

The world's best websites load before you've finished this sentence.
Those websites can't be static, but serving performance and personalization to a global user base has historically been complex.
The primary goal of Vercel's Frontend Cloud is to collect industry-best practices into one easy-to-use workflow, integrating new and better solutions as they come.
In this article, we'll look at why speed and personalization matter to your business, and how the Frontend Cloud gives you abundant options for both.
Tinloof is an agency obsessed with delivering fast websites such as jewelry brand Jennifer Fisher, which went from a Shopify theme to a modern Next.js website that instantly loads with 80% less JavaScript.
We've upgraded our Managed Infrastructure resulting in up to 45% faster routing at p99 and reliability improvements for all plans.
When a request is made to a Vercel-managed site, traffic is routed to the nearest Edge Network region with our Anycast routing. Vercel processes the request, identifies the deployment to serve, and instantly retrieves related metadata about the requested deployment.
Now with optimized metadata retrieval and routing, this performance enhancement benefits all workloads. Responses to static resources are then fetched from storage, or dynamic content is generated through Vercel Functions, based on the routing details from the deployment metadata.
These infrastructure improvements benefit all existing and new deployments. Deploy now or learn more about Vercel's Managed Infrastructure.
Following the Node.js 16 end of life on September 11, 2023, we are deprecating Node.js 16 for Builds and Functions on January 31, 2025.
Will my existing deployments be affected?
No, existing deployments with Serverless Functions will not be affected.
When will I no longer be able to use Node.js 16?
On January 31, 2025, Node.js 16 will be disabled in project settings. Existing projects using 16 as the version for Functions will display an error when a new deployment is created.
How can I upgrade my Node.js version?
You can configure your Node.js version in project settings or through the engines field in package.json.
How can I see which of my projects are affected?
You can see which of your projects are affected by this deprecation with:
Translating designer brand experiences to the digital world requires putting complete control in the hands of the developer. A lack of ability to fine-tune performance optimizations and application decisions often limits UI possibilities.
Ruby v3.2 is now generally available, and is the new default runtime version for Ruby based Builds and Serverless Functions. Additionally, Ruby v2.7 will be discontinued on December 7th, 2023.
Existing deployments that use Ruby v2.7 will continue to work
New deployments will use Ruby v3.2 by default, or if ruby "~> 3.2.x" is defined in the Gemfile
After December 7th, 2023, new deployments that define ruby "~> 2.7.x" in the Gemfile will no longer build
Only the minor version (3.2) is guaranteed, meaning we will always use the latest patch version available within the minor range.

Core web app decisions tend to center the backend, due to its complexity and impact over huge swaths of the business.
However, frontends have grown far more important and complex in their own right. When not prioritized, the intricate infrastructure around them can quickly spin out of control, dragging teams into untold amounts of tech debt.
As decoupled architecture becomes more common, developers are turning to the Frontend Cloud to automate away the behind-the-scenes hassles of creating and growing dynamic websites.
Instead of managing infrastructure as a separate step of the development process, the Frontend Cloud provisions global infrastructure for you, based on your existing application code.
This approach to web development massively increases developer velocity, allowing your team to experiment safely and meet shifting market demands. Teams of all sizes can effortlessly scale global apps while maintaining the highest possible bars for performance, personalization, and security.
You can think of the backend cloud as your cost center and the Frontend Cloud as your profit center.
Comments on your deployments can now be converted into Jira issues. This makes it easy to take action on feedback in the workflows your team is already using.
You can name your issue and select the project and issue type without leaving your deployment. Issues retain the full thread history with any attached images and include a link back to where the comment was left.
Jira is part of our growing collection of integrations for comments which includes Slack and Linear, available to Pro and Enterprise users as well as Hobby users with public git repositories.

Scaling a codebase is an integral, and inevitable, part of growing a software company.
You may have heard many terms thrown around as answers — monoliths, monorepos, micro frontends, module federation, and more.
At Vercel, we’ve helped thousands of large organizations evolve their codebases, and we have an opinion on the optimal way to build software.
As of today, Node.js version 20 can be used as the runtime for Builds and Serverless Functions. Select 20.x in the Node.js Version section on the General page in the Project Settings. The default version remains Node.js 18.
Node.js 20 introduces several new features including:
New experimental permission model
Synchronous import.meta.resolve
Stable test runner
Performance updates to V8 JavaScript Engine and Ada (URL Parser)
Node.js 20 is faster and introduces new core APIs eliminating the need for some third-party libraries in your project. Support for Node.js 20 on Vercel is currently in beta.
The exact version used by Vercel is 20.5.1 and will automatically update minor and patch releases. Therefore, only the major version (20.x) is guaranteed.
Read the documentation for more.
Vercel Cron Jobs let you to run scheduled jobs for things like data backups or archives, triggering updates to third-party APIs, sending email and Slack notifications, or any task you need to run on a schedule.
By using a specific syntax called a cron expression, you can define the frequency and timing of each task. Cron Jobs work with any frontend framework and can be defined in vercel.json. You can use them to run your Serverless Functions and Edge Functions.
During the beta, we made Cron Jobs more secure by providing an environment variable with the name CRON_SECRET. We also added support for Deployment Protection and Instant Rollback.
Cron Jobs are now included for customers on all plans. Per account, users on the Hobby plan will have access to 2 Cron Jobs, users on the Pro plan will have access to 40 Cron Jobs, and users on the Enterprise plan will have access to 100 Cron Jobs.
Check out our documentation or deploy an example with Cron Jobs.
Vercel can now automatically detect and replay layout shifts on your deployments from the Vercel Toolbar.
Layout shifts are reported and notified through the Toolbar. Each reported shift includes a summary of what caused the shift and how many elements it affected. Additionally, you replay and animate the shift to see it again.
The Toolbar is automatically added to all Preview Deployments, but can also be used in localhost and in production (likely behind your own staff authentication checks) when using the @vercel/toolbar package.
Check out the documentation to learn more.
At this year’s Next.js Conf, we discussed the developer and user experience challenges of global delivery of dynamic web applications. How can we fetch data without expensive waterfalls and also deliver content directly from the edge?
The answer to all of these current challenges: Partial Prerendering (PPR).
PPR combines ultra-quick static edge delivery with fully dynamic capabilities and we believe it has the potential to become the default rendering model for web applications, bringing together the best of static site generation and dynamic delivery.
Today, you can try an experimental preview of PPR with Next.js 14 on Vercel or visit our demo for a first impression of PPR.
A security vulnerability was discovered that affects Sentry’s Next.js SDK, which made it possible to exploit Sentry’s Tunnel feature to establish Server-Side Request Forgery (SSRF) attacks.
The Sentry team has already released a patch with the latest version 7.77.0.
While we still recommend updating to the latest version of the Sentry SDK, Vercel has taken proactive measures on our firewall to protect our customers.
We will continue to proactively protect all Sentry + Next.js deployments on Vercel through the Vercel Firewall, regardless of Sentry's Next.js SDK version running.
Vercel Edge Config is our global low-latency data store for feature flags, experiments, and configuration metadata. Now, backups of your Edge Config are automatically created with every update to an Edge Config's items. You can restore backups from the Storage tab in your Vercel dashboard.
Customers on all plans can take advantage of backups. Hobby customers have 7 days of backup retention, Pro customers have 90 days of backup retention, and Enterprise customers have 365 days of backup retention.
Check out the documentation to learn more.
You will now see more information in the build logs when your build fails due to either exhausting the available memory (OOM) or disk space (ENOSPC).
In the case of OOM, your build logs will confirm the event. For ENOSPC situations, detailed information on disk space allocation is provided.
Check out our documentation to learn more.
We recently introduced an improved project and team switcher on Vercel, including the option to favorite projects.
Now, favorited projects will also appear in your dashboard overview, and you can easily add and remove them from the context menu.
At this year's Next.js Conf, thousands of community members tuned in to learn about updates to the framework thousands of developers deploy with everyday. Among the announcements were:
Web Apps are the ultimate dynamic use-case on the Web. As opposed to websites, web apps typically require or facilitate user-to-data interactions. Applications like customer-facing dashboards, support portals, internal employee apps, and much more require up-to-date, personalized information delivered in a performant and secure way.
Vercel's Frontend Cloud offers support for deploying complex and dynamic web applications with managed infrastructure so you have control and flexibility without having to worry about configuration and maintenance—and yes, this means everything required to serve your App.
Deployment Protection is now enabled by default for all new projects, and our full set of protection options is now generally available.
Deployment Protection includes a series of features that ensure you can keep your Vercel deployments secure. Secure your Preview and Production deployments with:
Vercel Authentication: Restricts access to your deployments to only Vercel users with suitable access rights. Vercel Authentication is available on all plans.
Password Protection: Restricts access to your deployments to only users with the correct password. Password Protection is available on the Enterprise plan, or as a paid add-on for Pro plans.
Trusted IPs: Restricts access to your deployments to only users with the correct IP address. Trusted IPs is available in addition to Vercel Authentication and available as a part of the Enterprise plan.
To configure existing deployments with Deployment Protection, you can use this migration guide. For all new deployments, Deployment Protection with Vercel Authentication is now enabled by default.
Check out the documentation to learn more.
Ensure your past production deployments remain secure by enabling Standard Protection as the default setting for your deployments. With Standard Protection, Vercel Authentication or Password Protection will ensure that all of your preview and production deployments remain secure.
Migrating existing deployments to use Standard Protection will protect both preview and generated production URLs. Standard Protection restricts access to the production generated deployment URL
Learn more about migrating to Standard Protection in our documentation.
Deployment Protection is available on all plans.
Trusted IPs are a feature of Deployment Protection that allow you to limit access to your deployments by IP address. Configure Trusted IPs in addition to Vercel Authentication to ensure only your team members can access and make changes to your deployments.
For customers who rely on a VPN or additional proxy, Trusted IPs ensure you can restrict access to your deployments to only users behind the VPN.
You can configure Trusted IPs by specifying a list of IPv4 addresses, or by CIDR ranges.
Trusted IP for Deployment Protection is only available for customers on the Enterprise plan.

Cookies are small pieces of data stored by web browsers on a user's device at the request of web servers. They are sent back unchanged by the browser each time it accesses that server. Cookies allow the server to "remember" specific user information, facilitating functionalities like maintaining user sessions, remembering preferences, and tracking user behavior.
Next.js 14 is fully supported on Vercel. Build data-driven, personalized experiences for your visitors with Next.js, and automatically deploy to Vercel with optimizations, including:
Streaming: The Next.js App Router natively supports streaming responses. Display instant loading states and stream in units of UI as they are rendered. Streaming is possible for Node.js and Edge runtimes—with no code changes—with Vercel Functions.
React Server Components: Server Components allow you to define data fetching at the component level, and easily express your caching and revalidation strategies. On Vercel, this is supported natively with Vercel Functions and the Vercel Data Cache, a new caching architecture that can store both static content and data fetches.
React Server Actions: Server Actions enable you to skip manually writing APIs and instead call JavaScript functions directly for data mutations. On Vercel, Server Actions use Vercel Functions.
Partial Prerendering (Experimental): A new compiler optimization for dynamic content with a fast initial static response based on a decade of research and development into server-side rendering (SSR), static-site generation (SSG), and incremental static revalidation (ISR).
Additionally in Next.js 14 you will find:
Turbopack: 5,000 tests passing for App & Pages Router with 53.3% faster local server startup and 94.7% faster code updates with Fast Refresh.
Forms and mutations: The user experience is improved when the user has a slow network connection, or when submitting a form from a lower powered device.
Metadata: Blocking and non-blocking metadata are now decoupled. Only a small subset of metadata options are blocking, and we ensured non-blocking metadata will not prevent a partially prerendered page from serving the static shell.
Logging: More verbose logging around fetch caching can be enabled.
create-next-app: There is now an 80% smaller function size for a basic create-next-app application.
Memory management: Enhanced memory management is available when using edge runtime in development.

In the latest version of Next.js, we've made improvements to optimize package imports, improving both local dev performance and production cold starts, when using large icon or component libraries or other dependencies that re-export hundreds or thousands of modules.
This post explains why this change was needed, how we've iterated towards our current solution, and what performance improvements we've seen.
Vercel Postgres, our serverless SQL database, is now available for Hobby and Pro users.
During the beta period, we reduced cold start times to 100-200ms and fixed several bugs around handling connections. Usage prices have also been lowered from the beta:
Total storage:
reduced 60% from $0.30/GB to $0.12/GB
Written data:
reduced 4% from $0.10/GB to $0.096/GB
Data transfer: reduced 55% from $0.20/GB to $0.09/GB
Billing will begin on October 19th and Pro users have the following usage included:
1 database then $1.00 USD per additional database
100 hours of compute time per month then $0.10 USD per additional compute-hour
512 MB total storage then $0.12 USD per additional GB
512 MB written data per month then $0.096 USD per additional GB
512 MB data transfer per month then $0.09 USD per additional GB
If you were a beta participant and want to opt out of using Vercel Postgres, you can backup your database and delete it.

With Vercel and Medusa at the helm of their frontend stack, Copenhagen-based bedding brand Tekla can handle high traffic while providing fast, personalized digital experiences to their customers.
Agilo, a digital design and development agency, wants to provide the best solutions possible for their clients. When the ecommerce brand Tekla turned to the agency for additional development support, Agilo came with a plan. By upgrading Tekla’s composable setup, the agency provided Tekla with enough speed and reliability to handle their growing traffic volume and deliver personalized digital experiences.
A few weeks ago, we introduced v0: a product that makes website creation as simple as describing your ideas. We call it Generative UI—combining the best practices of frontend development with the potential of generative AI.
The interest in v0 has been incredible, with 100,000 people registering for the waitlist in just three weeks. Today, we’re transitioning v0 from Alpha to Beta, rolling out access to 5,000 additional users, and introducing subscription plans for those who want to unlock the full v0 feature set.
At Vercel, we consistently monitor and update our security protocols to address emerging threats. A new vulnerability, known as the HTTP/2 Rapid Reset Attack (CVE-2023-44487), has the potential to disrupt HTTP/2-enabled web servers.
Rapid Reset is a vulnerability possible in the HTTP/2 protocol involving quickly initiating and canceling streams. It can be used to launch large denial-of-service attacks, negatively affecting performance and availability.
We've taken proactive steps to refine our infrastructure and strengthen our defenses. Our improved system can now more efficiently handle the HTTP/2 Rapid Reset Attack.
An essential component of our defense strategy is inline network traffic monitoring, where we identify malicious TCP connections and terminate them. Limiting abuse over a single connection has enabled Vercel to protect against HTTP/2 Rapid Reset Attack.
Combining our existing system with new improvements, all applications on Vercel are even further resistant to the HTTP/2 Rapid Reset Attack.
We want to assure you that your web assets are protected against the HTTP/2 Rapid Reset Attack. We're committed to consistently improving our security measures in response to new threats to ensure safety and reliability for all users.
Images are the most popular resource type on the web, yet understanding the nuances of various image formats and their technical attributes can be challenging.
Vercel's Slack integration now includes Comments. Once the Vercel Slack app is installed, you can subscribe to messages in a channel about all Comments made on your team's deployments or Comments made on specific projects.
If you configured the Slack app before October 4th, 2023, the updated app requires new permissions. You must reconfigure the app to subscribe to new Comment threads and link new channels.
You will get a Slack message for each new Comment, and replies in Slack will automatically appear in the Comment thread on your deployment. You can also log in to the integration with your Vercel account to get DMs about comments relevant to you.
Install the integration in our marketplace, or visit the documentation to learn more.
Vercel Web Analytics now supports tracking custom events on the server-side, in addition to existing support for client-side tracking.

Serverless infrastructure can instantly and infinitely scale. While powerful, this has had tradeoffs. An unforced error or traffic spike could cause an unexpected bill.
Today, we'll begin rolling out Spend management on the Pro plan for the Billing and Owner roles. You can recieve notifications and trigger webhooks when you pass a given spend amount on metered resources like Functions. The actions you can take are:
When your spending approaches or exceeds the set limit, you'll receive realtime notifications to help you stay in control. This includes Web and Email notifications at 50%, 75%, and 100%. Additionally, you can also receive SMS notifications when your spending reaches 100%.
Setting a spend amount does not mean your project with pause automatically. To programmatically take action based on your set amount, you can use a webhook to pause your project, or even put your site into maintenance mode.
Check out our documentation to learn more.
Navigating the web safely while ensuring user privacy is a top priority. When working with cookies, it’s important to ensure they are secure and serve their intended purpose without compromising user privacy.
One key attribute to consider is SameSite, which dictates when and how cookies are sent in cross-site requests.
You can now use ⌘K (or Ctrl+K on Windows) to open the Command Menu on any deployment where the Vercel Toolbar is enabled, including production and localhost. You can use Cmd + Shift + K if you're viewing a deployment of a website that has its own ⌘K menu.
Users can now navigate between a deployment and other Vercel pages relevant to the project directly through the menu.

L’Officiel Inc. is a century-old fashion media group representing 10 renowned publications in more than 80 countries. Despite its global reach, the brand has a small team that maintains its 30 web properties, while also developing new features and working on special projects sold to clients.
Based on your feedback, we’re improving Serverless Functions as follows:
Pro customers can now run longer functions for up to 5 minutes.
Pro customers default function timeout will be reduced to 15 seconds on October 1st.
These changes help prevent unintentional function usage, unless explicitly opted into the longer function duration.
Beginning October 1st, all new projects will receive a default timeout of 15 seconds. In addition, any projects that have not had functions run for more than 15 seconds will have their default timeouts reduced to 15 seconds.
To avoid unexpected timeouts, any projects that have had functions running for longer than 15 seconds (less than 1% of traffic) will not have their defaults changed.
Existing defaults still apply for Hobby and Enterprise customers.
Check out our documentation to learn more.
Vercel now supports Remix v2. Deploy your Remix application on Vercel with advanced support for:

The Vercel Postgres SDK has significantly improved performance for Postgres queries from Vercel Edge Functions.
The @vercel/postgres package has been updated to use the latest version of Neon’s Serverless driver which adds support for SQL-over-HTTP when you use the sql template literal tag. Simple queries that do not require transactions now complete in ~10ms—up to a 40% speed increase.
You do not need to make any changes to your queries to see these improvements, you only need to update to the latest version of @vercel/postgres to take advantage of these improvements.
We've added new options to the "Connected Git Repository" settings in the Vercel dashboard. It's now possible to configure whether the Vercel bot comments on:
Pull Requests
Production Commits
These settings are available for all connected repositories, not just GitHub repositories.
Previously, there was a github.silent setting available in vercel.json that didn't allow more granular control over disabling comments. We will be deprecating that option on Monday, September 25, 2023. There is no action required at this time to prepare for deprecation. Until that date, if you set that option in your vercel.json file we will continue to read it, and update the configuration in the dashboard accordingly.

In a previous blog post, we talked about why we are porting Turborepo, the high-performance build system for JavaScript and TypeScript, from Go to Rust. Now, let's talk about how.
Today, our porting effort is in full swing, moving more and more code to Rust. But when we were starting out, we had to make sure that porting was feasible for us to accomplish. A migration from one language to another is no small task and there's a lot of research to do up front to ensure that the end goal is attainable.
Here’s how we started the process, validated our current porting strategy, and made the call to port Turborepo to Rust.
React 18 has introduced concurrent features that fundamentally change the way React applications can be rendered. We'll explore how these latest features impact and improve your application's performance.

While reMarkable, pioneers of the next-generation paper tablet, can credit much of their initial success to their original website, they knew they’d need to improve key elements of their stack and workflow to reach new heights. The team opted for a composable stack—comprised of Sanity, Next.js, and Vercel—to meet the needs of their developers while empowering their content creators to deliver truly delightful digital experiences.
The ability to process data as it streams has always been a fundamental concept in computer science. JavaScript developers had access to streaming through XMLHttpRequest, but it wasn't until 2015 that it was accessible natively through the Fetch API.
Web streams provide a standardized way to continuously send or receive data asynchronously across network connections. They bring the power of streaming to the web, enabling developers to handle large data sets through "chunks", deal with congestion control (backpressure), and create highly efficient and responsive applications.
Leveraging web streams in your web apps can enhance the performance and responsiveness of your UIs. The immediate data processing allows for real-time updates and interactions, providing a seamless user experience with quicker load times, more up-to-date information, and a smoother, more interactive interface.
Due to their increasing popularity, the Web Streams API has become a cornerstone of many major web platforms, including web browsers, Node.js, and Deno. In this blog post, we’ll look at what web streams are; how they work, the many advantages they bring to the table for your website, streaming on Vercel, and tools built around web streams that we can use today.
Neo Financial is a next-generation banking app and Canada’s fastest-growing financial services company. They’re leveraging Vercel's frontend cloud to enhance their web development process, boost performance, and meet industry security standards—all while saving on resources.
Today we’re excited to announce updates to Draft Mode, making it easier to see your latest content changes before they’re published.
Draft Mode goes hand in hand with Visual Editing, our real-time content editing feature for websites using headless Content Management Systems (CMSes). When you make changes through Visual Editing, you can guarantee that your edits will show up the next time the page is viewed in Draft Mode.
Draft Mode: Users on any plan can now enable Draft Mode from the Vercel toolbar. When you do so, the toolbar color changes to purple to indicate you are viewing draft content.
Skew Protection: You can now implement Skew Protection to eliminate version skew between web clients and servers on Next.js version 13.4.7 or newer. The Skew Protection platform primitive is available to all frameworks.
Storage transfers: When Hobby users upgrade to Pro, their stores will be transferred to the new team.
Configured Ignored Build Step script: When rebuilding or promoting a deployment in a project with a Ignored Build Step script now you can explicitly skip the ignore build step script, forcing the build to happen.
System environment variables: VERCEL_BRANCH_URL with the generated Git branch URL has been added to the system env vars to access a deployment’s Git branch alias from within their code.
Faster deployment times: Projects with Edge Functions are now faster to deploy by: 2 seconds on average, 9 seconds in slow cases, and up a 20 second improvement in the slowest case.
Git metadata: You can now see Git metadata for deployments when there are unstaged changes.
Vercel CLI: v30.2.3 was published with updates to dependencies for Node and Remix.
Have you ever seen a 404 for requests from old clients after a deployment? Or gotten a 500 error because the client didn’t know that a new server deployment changed an API? We're introducing a generic fix for this problem space.
Vercel customers are deploying over 6 million times per month, making their businesses more successful one commit at a time. But since the dawn of the distributed computing age, each system deployment has introduced the risk of breakage: When client and server deployments aren’t perfectly in sync, and they won’t be, then calls between them can lead to unexpected behavior.
We call this issue version skew. In the worst case, version skew can break your app, and in the best case, it leads to substantial extra engineering effort as software changes crossing system boundaries must be backward and forward-compatible.
Today, we're introducing Skew Protection for deployments, a novel mechanism to eliminate version skew between web clients and servers. This technology will substantially reduce errors users observe as new deployments are rolled out. Additionally, it will increase developer productivity as you no longer need to worry about backward and forward compatibility of your API changes. Available today for everyone in Next.js and SvelteKit with Nuxt and Astro coming soon.
Svelte has made a name for itself in the world of web development frameworks, thanks to its unique approach of converting components into optimized JavaScript modules. This innovative way of rendering apps eliminates the overhead found in traditional frameworks, leading to more performant and efficient applications.
With the release of SvelteKit 1.0, developers can leverage the power of fullstack Svelte without worrying about breaking changes. Furthermore, SvelteKit continues to evolve, offering a robust set of features and seamless integration with various deployment environments, including Vercel.
Vercel, using framework-defined infrastructure (FDI), has embraced SvelteKit, recently adding support for per-route configuration for Serverless and Edge Functions, Incremental Static Regeneration (ISR), and easier compatibility with a range of Vercel products. In this article, we'll explore how to make your apps more performant, scalable, and user friendly.

We've been partnering with Nuxt to further integrate the framework with Vercel and support all Vercel products. Nuxt on Vercel now supports:
We’re in the midst of the next big platform shift. Last generation we moved from server rooms to the cloud, and today we’re moving from the traditional, backend-oriented cloud to a new frontend cloud.
The frontend cloud is characterized by performance: It enables both faster application development and faster end-user interactions. Each element is critical to success in today’s ultra-competitive software market.
At Clerk, we build authentication for the frontend cloud. We saw the need arise as frameworks and hosts tailored to the frontend cloud grew in popularity, especially Next.js and Vercel. Legacy authentication tools were not built frontend-first, and their technical architecture usually undermines the goal of speeding up end-user interactions, since they’re slow at the edge.
Vercel Data Cache is now available to give you framework-defined caching and propagation infrastructure to handle responses from React Server Components.
Data Cache is a globally distributed, ephemeral cache accessible from both serverless and edge runtimes, allowing you to cache data granularly in the region in which your function executes, with different treatments depending on the type of response:
Dynamic data is re-fetched with every execution
Static data is cached and revalidated either by time-based or on-demand revalidation
This feature is currently supported for the Next.js App Router and is available for users on all plans.
Check out our documentation and usage limits to learn more.
The Next.js App Router, now stable in Next.js 13.4 is supported out-of-the-box on Vercel, with pre-configured, global, framework-defined infrastructure.

Nested Routes and Layouts: Easily share UI between routes while preserving state and avoiding expensive re-renders. On Vercel, your layouts and pages can be configured to deploy as Edge Functions, delivering substantial SEO and performance improvements.
Streaming: The Next.js App router natively supports streaming responses. Display instant loading states and stream in units of UI as they are rendered. Streaming is possible for Node and Edge runtimes—with no code changes—with Vercel Functions.
React Server Components: Server Components allow you to define data fetching at the component level, and easily express your caching and revalidation strategies. On Vercel, this is supported natively with Vercel Functions and Vercel Data Cache, a new caching architecture that can store both static content and data fetches.
Support for Data Fetching: With granular caching, Next.js allows you to choose from static or dynamic data at the fetch level. On Vercel, the Data Cache is automatically shared across deployments, speeding up build times and improving performance.
Built-in SEO Support: With the Metadata API, easily customize your page for sharing on the web, compatible with streaming.

Wunderman Thompson, a global digital agency, specializes in helping brands create and manage their digital presence.
Their teams based in Europe often serve multiple countries and languages, catering to the needs of various portfolio brands, each with its own unique identity.
To tackle these challenges, Wunderman Thompson uses the principles of Atomic Design, a headless CMS, a monorepo workflow, and Vercel's serverless platform. This approach cuts development time by a factor of 10 and costs by a factor of 25 compared to their former method of PHP servers and WordPress monoliths.
In this guide, we'll discuss the importance of choosing the right framework for an efficient developer workflow, and walk you through how to use these techniques to create your own efficient design system deployed on Vercel and the headless CMS of your choice.
Vercel Secure Compute enables creating private connections between Vercel Serverless Functions and your backend cloud, like databases inside VPCs and other private infrastructure.
Enterprise customers can now opt-into deploying to a isolated private network with dedicated IP addresses. This includes all production and preview traffic. Additionally, builds can be placed in specific regions and isolated from other customers.
Secure Compute improves the security and compliance of your deployments on Vercel. For more information about Vercel Secure Compute on Enterprise, or if you require support for VPC peering or VPN connections, please contact our sales team.
mmm.page was founded to provide anyone with the tools to create their own website, regardless of their technical know-how. With fast and early success, having the whole platform as a single page application on Amazon Simple Storage Service (Amazon S3) became untenable as the user base grew into the tens of thousands. That’s why they turned to Vercel. Thanks to Server-Side Rendering (SSR), ease of deployment, and support for custom domains, Vercel makes it simple to manage mmm.page’s scale, monetize their offerings, and continue to innovate.
Configuration data is used to control everything from A/B testing and feature flags to advanced rewrites and bespoke request-blocking rules. However, traditional solutions for managing configuration data can be slow, unreliable, and difficult to scale, which can negatively impact the user experience, latency, and overall effectiveness of your website.
Today we’re announcing the general availability of Edge Config, a new solution for managing configuration data in the cloud designed to be ultra-fast, reliable, and scalable, which can help improve your website's performance and efficiency.
With Vercel Edge Config you can perform ultra-low latency reads from Vercel Edge Middleware, Edge Functions, and Serverless Functions. Edge Config gives you a place to store your experimentation data like feature flags and A/B testing cohorts, and configuration data for middleware routing rules like redirects or blocklists.
Edge Config is now available for all Vercel users. Hobby users can perform 50,000 reads per month. Pro and Enterprise users can perform 1,000,000 reads per month, with additional usage available on-demand for an additional charge.

AWS and Vercel have always had a shared vision: accelerating innovation through the power of serverless computing—and helping customers win big in the process.
Vercel Edge Middleware and Edge Functions now support more Node.js modules. You may want to make use of these modules directly, but many of these low-level APIs are pieces of core functionality that other modules depend on. Adding support for these APIs expands the compatibility of existing npm packages.
The following APIs are now supported:
AsyncLocalStorage: Support for maintaining data for an invocation between different asynchronous execution contexts, which allows you to pass state to the context even when the function is hot and module context is preserved.
EventEmitter: A flexible API to build event-driven systems that serves as a core building block for communication between libraries that control I/O and listeners that process data when events occur.
Buffer: The most common way of handling binary data in Node.js, available globally or importable from buffer.
assert: A set of assertion functions to validate invariants and logical rules that are very useful to explicitly test assumptions in your code path that need to run in Edge Functions.
util.promisify and util.callbackify: A helper function to convert a callback-style function signature into one that returns a Promise, and a helper function to convert a function that returns a Promise into one that accepts a callback.
util.types: A set of functions to validate that objects are of a given type.
You can take advantage of these additional APIs in Edge Middleware and Edge Functions with your next deployment. To deploy Edge Functions on Vercel you can get started with any framework or one of our templates.
Vercel now supports Git LFS, enabling storing large files using your git client of choice.
Git LFS is free for all plans and can be toggled on and off in your project settings. File storage may consume additional bandwidth with your git provider that stores files (GitHub, GitLab, Bitbucket, etc.).
Check out our documentation to learn more.
Managing the complex scaling needs of an online ticketing platform can be challenging. For the French end-to-end ticketing solution Shotgun, ticket drops used to involve stress around scaling and server provisioning. As a company dedicated to providing artists and their fans with the best service, Shotgun now relies on Vercel for seamless launches. So when they drop tickets for artists like Billie Eilish, the team can rest assured their site can handle the traffic.
Since 2012, Google Optimize has been helping web builders experiment with their UIs to find the most effective patterns for their applications. However, Google has announced that Optimize will be sunset on September 30, 2023.
Vercel is ready to help you build a platform to continue your research with higher performance, more control, and better data by leveraging the edge.
Vercel recently became the first serverless computing provider to offer stable support for HTTP response streaming in both Node.js (Lambda) and Edge runtimes. This capability helps developers architect high-performance web applications with a focus on speed, scalability, and efficient resource usage.
Let’s take a look at how Vercel enables streaming for serverless Node.js environments, and how this capability can significantly boost your web app's performance and user experience.
As web developers, we know the importance of typography in design. Custom fonts can set the tone for a website and enhance its overall aesthetic. However, using custom fonts can often create issues with website performance and user experience.
One of the biggest issues with custom fonts is the Cumulative Layout Shift (CLS) that occurs when a font takes too long to load. These Flashes of Unstyled Content (FOUC) can alter the positioning of elements already on the page and make it difficult to navigate. CLS and FOUC can also impact an application's search engine ranking.
On Vercel’s external websites, we used to solve these problems with the workarounds that we’ll talk about below. However, with the release of Next.js 13, we switched to next/font, which cut down on complex code, client-side JavaScript, and layout shift.
Vercel now supports pnpm v8. For deployments with a pnpm-lock.yaml file with lockfileVersion: '6.0', Vercel will automatically use pnpm v8 for install and build commands.
To upgrade your project to pnpm v8, run pnpm install -g pnpm@8 locally and then re-run pnpm install to generate the new pnpm-lock.yaml file. After updating, create a new deployment for the changes to take effect.
If you want to specify an exact version of pnpm in your Vercel project, enable Corepack (experimental).
Check out the documentation to learn more.
A/B testing and experiments help you build a culture of growth. Instead of guessing what experiences will work best for your users, you can build, iterate, and adapt with data-driven insights to produce the most effective UI possible.
In this article, you'll learn how we built a high-performance experimentation engine for vercel.com using Next.js and Vercel Edge Config, allowing our developers to create experiments that load instantly with zero Cumulative Layout Shift (CLS) and a great developer experience.

Improved date picker: The new date picker in the Usage tab includes natural language parsing, presets, and shortcuts.
Vercel Cron Jobs: We now allow framework authors to create Cron Jobs via the crons property of the Build Output API configuration and creating Cron Jobs via the crons property of vercel.json for end users.
Infrastructure as code (IaC) is the industry-standard practice for provisioning infrastructure in a repeatable and reliable way. Framework-defined infrastructure (FdI) is an evolution of IaC, where the deployment environment automatically provisions infrastructure derived from the framework and the applications written in it.
The best way to understand it is that a build-time program parses the source code written to a framework, understands the intent behind the code, and then automatically generates the IaC configuration needed to run the software. This means more predictable, lower cost, and lower risk DevOps through truly serverless—dare we say, infrastructureless—architecture.
In this article, we’ll explain how framework-defined infrastructure fits into modern views of infrastructure definition and automation. We’ll then show examples of how framework-defined infrastructure improves the experience of developing in open-source frameworks.
We’re excited to share some new additions to our observability suite: Monitoring, now generally available for Pro and Enterprise teams and Logs for users on all plans. These tools give teams on Vercel the ability to quickly identify and resolve issues before they become major problems with an aggregated view of web traffic and performance data.
Monitoring helps you detect and diagnose issues in your web applications by surfacing errors, traffic, and performance data. You can leverage example queries like Bandwidth by Project or Requests by Bot or create your own to quickly resolve issues and optimize your projects.
Monitoring is available for Pro and Enterprise users with 30 days data retention for Pro and 90 days data retention for Enterprise.

Let’s get back to basics and explore what headless commerce is, how it compares to monolithic commerce, and what you should do once you've made the migration to outpace your competitors and reach your KPIs.
The web is any traveler’s first stop when it comes to planning vacations. Cruise Critic (a subsidiary of Tripadvisor) knows just how essential review sites are to today’s traveler; the company serves six million visitors every month. Growing traffic meant that Cruise Critic needed to evaluate their application stack as well as their development workflow in order to scale.
Before today, developers had to choose between either fully static or fully dynamic pages.
With Next.js 13.2, we’re excited to announce the Next.js Cache (beta) and the brand-new Vercel Data Cache (beta). This enables caching only part of your page as static data, while fully dynamically rendering the rest of your application, including accessing real-time and personalized data.
Plenti is a technology-led consumer lending and investment company that helps borrowers bring their big ideas to life. Established in Australia in 2014, Plenti has funded over $900m of loans to over 55,000 borrowers and has attracted over 22,000 registered investors.
Consumers hold financial services providers to high standards, so a Vercel and Next.js frontend was instrumental in transforming their brand and giving their users a trustworthy experience.
Because of this, migrating from their WordPress-based monolithic stack and launching a composable Next.js frontend on Vercel was Plenti’s top tech priority as they approached their rebrand and IPO.
And they did this all with a one-developer team.

“We catch people’s attention with cutting-edge technology that they’ve never seen, much less experienced,” says Dave Boyle, Head of Development at Globacore.
After going from $13M to $100M in revenue in two years, HR platform Rippling needed a frontend stack as fast and flexible as its innovative solutions.
As they scaled to over 600 pages, engineer Robert Schneiderman realized that a fullstack WordPress solution wouldn't be able to handle their stakeholders' rapid iteration needs while maintaining the performance their customers require. By leveraging Next.js and Vercel alongside their WordPress headless CMS, Rippling was able to build a solution that kept developers, content creators, and customers happy.
As the company grows, teams across Rippling are empowered to make the changes they need. Over 90% of site changes are deployed by stakeholders immediately, giving Schneiderman the freedom to keep improving Rippling’s site performance and user experience.
Vercel Cron Jobs enable you to run scheduled jobs for automating backups and archiving, sending email and Slack notifications, and more. Cron jobs can be used for any task you need to run on a schedule.

KidSuper is a Brooklyn-based cult streetwear label and hybrid art brand with strong ties to the music, sports, and tech communities. From collaborating with the likes of Puma and Nike to co-designing Louis Vuitton's 2023 menswear collection, founder Colm Dillane and CTO Adham Foda are known worldwide for their boundary-pushing approach to fashion.
The brand went viral in 2011 after Mac Miller wore their apparel on the cover of iTunes, and the duo knew they’d eventually require a tech solution that could keep up with their creativity. They needed to branch out from their Shopify-managed storefront and go headless, allowing them to bring their vision to life.
We held our biggest ever Next.js Conference on October 25, 2022 with over 110,000 registered developers, 55,000 online attendees, and hundreds attending in person in San Fransisco. We had photographers on site to capture the experience and we wanted to share the photos they took with the community.
Instead of just sharing photos with a Google Drive link, we thought it’d be good idea to showcase these 350+ amazing photos in an image gallery that was fast, functional, and beautiful. We ended up building our own and open sourcing the code, making it easy for anyone to build their own image gallery.
In this blog post, we’re going to share the techniques we used to build a performant image gallery site that can handle hundreds of large images and deliver a great user experience.
You can now link to specific Build Log lines or groups of Build Logs to help point to a specific section of the output when sharing.

Next.js lets developers iterate on their projects faster—but we want to iterate on Next.js itself faster, too.
This year, Next.js surpassed 4 million npm downloads for the first time. With over 2,400+ contributors, the core team here at Vercel must craft a developer experience to keep up with such a vast community to develop, test, build, and publish Next.js.
Next.js had another first this year: introducing Rust to its core. While adding Rust brings greatly improved performance for developers using Next.js, the tradeoff was an increase in CI time to publish new releases due to the prolonged process of building Rust binaries.
Until implementing Turborepo Remote Caching dropped publish times by 80%.
Optimizing your Next.js site for performance and efficiency can be complicated, but a good developer toolkit can help. Hear from some of the experts from this year’s Next.js Conf to see how you can best use React Server Components, the latest in web UI, powerful layouts, and more to create a world-class website.

One of the main benefits of building with Next.js is the ease of leveraging APIs and components to quickly integrate with best-of-breed, backend technology.
Today released our new notification system as a public beta, made possible with the help of our integration partner Knock, their powerful API, and robust component library.
This post will cover how we chose and implemented Knock for our notification center, and how you can use Knock to build notifications into your own application.
Last month we announced the limited availability of Vercel Edge Config, an ultra-low latency data store for near-instant reads of configuration data.
Edge Config is now generally available, alongside integrations with Statsig and HappyKit for A/B testing and Feature Flags.
Access to fast, global compute can give developers more flexibility to build rich experiences, regardless of their users' physical location or network speed. Vercel's Edge Functions aim to bring this capability into every developer's toolkit for building on the Web.
This past summer, alongside our GA of Edge Middleware, we released Edge Functions to Public Beta. During our beta period, our Edge Network has seen over 30 billion Edge Function invocations.
Since launching, we’ve made Edge Functions faster, more flexible, and capable of even larger workloads:
Edge Config allows you to distribute data to our Edge Network without needing to perform a deployment. Instead, your data is actively replicated to all our regions before it’s requested. This means your data will always be available instantly, with most lookups returning in 5 ms or less, and 99% of reads returning under 15 ms.
Edge Config is now available in public beta—you can get started with our new Statsig and HappyKit integrations, Edge Config SDK, or by using one of our examples.
Check out the documentation to learn more.
The new notification experience, now in public beta, allows you to configure alerts to land in your email and/or the Vercel dashboard for all notification types. Additionally, you can now configure your notification settings to group misconfigured domains into a single notification on desktop, preventing an influx of unwanted or repetitive emails.
Start configuring your notifications more granularly to increase the signal for:
Usage
Domain alerts
Team invites
Deployment failures
Check out the documentation to learn more.
During the private beta, we’ve made Edge Functions faster, more flexible, and more compatible with Node.js:
Major infrastructure optimizations for improved performance
Support for
cache-control
for function responses
Added ability to express
Added support for
Increased function size limits
for Enterprise and Pro teams
We’re excited to announce that beginning today, Edge Functions are now generally available so you can start executing more efficiently with instant “cold starts” to your functions for a better end-user experience.

Instafest allows users to quickly create a festival poster from their top Spotify, Apple Music, and Last.fm artists. Anshay Saboo, a Computer Science student at USC, used Next.js and Vercel to launch Instafest fast and scale to 500,000 new users per hour, gaining millions of users and going viral on Twitter, TikTok, and more.
If your company started building with React over 5 years ago, chances are you implemented your own custom solution or internal framework. Many engineers and teams want to explore technologies like Next.js and Vercel. However, some don't know where to get started because it's so far from their current reality or they don't see how supporting a custom framework is holding them back.
As a coding exercise, we wanted to show what this could look like by migrating a large, open-source React application to use Next.js.
We managed to remove 20,000+ lines of code and 30+ dependencies, all while improving the local iteration speed of making changes from 1.3s to 131ms. This post will share exactly how we incrementally adopted Next.js and Vercel to rebuild the BBC website.
New Relic is a fullstack application monitoring platform used by the world's top development teams.
With the integration, you can stream function, error, and build logs from your Vercel projects to a pre-built dashboard in New Relic. This allows you to observe key metrics like cache hit rate, 4xx and 5xx error log counts, and the performance of your Serverless Functions for rapid troubleshooting and optimization.
Try out the integration for instant observability.
Last week, I joined Holly Mesrobian, AWS VP of Serverless Compute, on stage at AWS re:Invent in Las Vegas. We discussed our shared vision of accelerating innovation with serverless computing, and how Vercel has leveraged AWS Lambda over the years.
Starting December 5, 2022, Enterprise plan users in the Developer role will be able to initiate a build when committing to the main branch of a Git project. This change ensures closer alignment with the security controls in your git environment.
Currently, users assigned the Developer role can only initiate a build when they commit to the main branch of a project if they are promoted to the Project Administrator role.
We suggest Enterprise plan customers review their policies in their Git environment to manage how users commit to the main branch.
Learn more about Enterprise team roles and permissions.
You can now use Instant Rollback on the CLI to quickly revert to a previous production deployment, to prevent regressions with your site’s availability. Now available in Beta for all plans.

DatoCMS provides over 25,000 businesses with a headless CMS built for the modern Web. Since their users rely on them for speed and innovation, they needed to find a fix fast when build times grew and complexity increased on their static CDN. By switching to Next.js on Vercel, the team was able to cut build times by 60% while achieving both a better developer experience and simpler infrastructure.
Scale is a data platform company serving machine learning teams at places like Lyft, SAP, and Nuro. It might come as a surprise to learn that they do all this with only three designers. Their secret to scaling fast: Vercel and Next.js.
justInCase Technologies’ development team needed a platform that would allow them to deliver a faster user experience without sacrificing developer experience. They struggled with their cloud platform’s infrastructure, with GitHub previews on a previous solution often getting stuck on the queued stage and failing. Not only were builds slow, they were also unreliable.
Once they made the switch to Vercel, they no longer faced preview failures. With 50% faster builds, they now save 72 hours of developer time per month.
Loom, a video communication platform, helps teams create easy-to-use screen recordings to support seamless collaboration. Loom places high value on developer experience, but never wants to sacrifice user experience. Going headless with Next.js on Vercel, they can achieve both. By leaning on best-of-breed tools, all seamlessly embedded in their frontend, Loom's developers empower stakeholders, while the engineering team continues to bring new features to market.
Today, we're introducing Edge Config: an ultra-low latency data store for configuration data.

Writing documentation is a collaborative process—and feedback should be too. With the release of Next.js 13, we looked to the community to ensure our docs are as clear, easy to digest, and comprehensive as possible.
To help make it happen, we enabled the new Vercel commenting feature (beta) on the Next.js 13 docs. With 2,286 total participants, 509 discussion threads, and 347 resolved issues so far, our community-powered docs are on track to be the highest quality yet.
Visit beta.nextjs.org/docs to give it a try.
Vercel's mission is to provide the speed and reliability innovators need to create at the moment of inspiration. Last year, we focused on speeding up the way Next.js bundles your apps.
Each time we moved from a JavaScript-based tool to a Rust-based one, we saw enormous improvements. We migrated away from Babel, which resulted in 17x faster transpilation. We replaced Terser, which resulted in 6x faster minification to reduce load times and bandwidth usage.
There was one hurdle left: webpack. Webpack has been downloaded over 3 billion times. It’s become an integral part of building the web, but it's time to go faster.
Today, we’re launching Turbopack: a high-performance bundler for React Server Components and TypeScript codebases.
The future of web analytics is real-time and privacy-first. Today, we're excited to announce our acquisition of Splitbee—bringing more analytics capabilities to all Vercel customers.

WebGL is a JavaScript API for rendering 3D graphics within a web browser, giving developers the ability to create unique, delightful graphics, unlike anything a static image is capable of. By leveraging WebGL, we were able to take what would have been a static conference signup and turned it into the immersive Next.js Conf registration page.
In this post, we will show you how to recreate the centerpiece for this experience using open-source WebGL tooling—including a new tool created by Vercel engineers to address performance difficulties around 3D rendering in the browser.
As we work to make a faster Web, increasing speed typically looks like moving more towards the edge—but sometimes requests are served fastest when those computing resources are close to a data source.
Today, we’re introducing regional execution of Edge Functions to address this. Regional execution of Edge Functions allow you to specify the region your Edge Function executes in. This capability allows you to run your functions near your data to avoid high-latency waterfalls while taking advantage of the fast cold start times of Edge Functions and ensuring your users have the best experience possible.
Vercel Edge Functions can now be deployed to a specific region.
By default, Edge Functions run in every Vercel region globally. You can now deploy Edge Functions to a specific region, which allows you to place compute closer to your database. This keeps latency low due to the close geographical distance between your Function and your data layer.

With your feedback, we've shipped bug fixes and small feature requests to improve your product experience.
Vercel CLI: v28.4.5 was released with bug fixes and improved JSON parsing.
A new system environment variable: VERCEL_GIT_PREVIOUS_SHA is now available in the Ignored Build Step, allowing scripts to compare changes against the SHA of the last successful deployment for the current project, and branch.
Vercel dashboard navigation: We’ve made it easier to navigate around the dashboard with the Command Menu. You can now search for a specific setting and get linked right to it on the page.
More granular deployment durations: The total duration time shown in the deployment tab on the Vercel dashboard now includes all 3 steps (building, checking, and assigning domains) and the time stamp next to each step is no longer rounded up.
Transferring projects: When transferring a project, the current team is always shown in the dropdown, disabled, with a "Current" label at the end. This is to prevent users from trying to transfer a project to the same Hobby team it already is in and also to keep the current team context.
Improved deployment logs: Logs that start with npm ERR! are now highlighted in red in deployment logs.
CLI docs revamp: The Vercel CLI docs have moved and now include release phases and plan call-outs.
Build environment updates: Node.js updated to v16.16.0, npm updated to v8.11.0, pnpm updated to v7.12.2.

The Next.js team at Vercel released the Layouts RFC a few months ago outlining the vision for the future of routing, layouts, and data fetching in the framework. The RFC is detailed and covers both basic and advanced features.
This post will cover the most important features of the upcoming Next.js changes landing in the next major version that you should be aware of.
When we created Next.js in 2016, we set out to make it easier for developers to create fast and scalable web applications, and over the years, Next.js has become one of the most popular React frameworks. We’re excited to release Next.js 12.3 which includes Fast Refresh for .env files, improvements to the Image Component, and updates to upcoming routing features.
While these Next.js features work out of the box when self-hosting, Vercel natively supports and extends them, allowing teams to improve their workflow and iterate faster while building and sharing software with the world.
Let’s take a look at how these new Next.js features are enhanced on Vercel.
Customers on the Enterprise plan can now export up to 90 days of Audit Logs to a CSV file.
Audit Logs allow team owners to track important events that occurred on their team including who performed an action, what action was taken, and when it was performed.

When inspiration struck Benjamin Td to visualize train routes across Europe, he created a Next.js application on Vercel in the moment of inspiration. To his surprise, his project ended up generating over a million views, reaching the top of Hacker News and going viral on Twitter.
We are excited to announce the launch of the Vercel Templates Marketplace.
Running A/B tests is hard.
We all know how important it is for our business–it helps us understand how users are interacting with our products in the real world.
However, a lot of the A/B testing solutions are done on the client side, which introduces layout shift as variants are dynamically injected after the initial page load. This negatively impacts your websites performance and creates a subpar user experience.
To get the best of both worlds, we built Edge Middleware: code that runs before serving requests from the edge cache. This enables developers to perform rewrites at the edge to show different variants of the same page to different users.
Today, we'll take a look at a real-world example of how we used Edge Middleware to A/B test our new Templates page.
We’re excited to announce the third annual Next.js Conf on October 25, 2022. Claim your ticket now.
It's now easier to test out a new framework,

We want to keep the Vercel Dashboard fast for every customer, especially as we add and improve features. Aiming to lift our Core Web Vitals, our Engineering Team took the Lighthouse score for our Dashboard from 51 to 94.
We were able to confirm that our improvements had a real impact on our users over time using Vercel Analytics, noting that our Vercel Analytics scores went from 90 to 95 on average (desktop). Let’s review the techniques and strategies we used so you can make a data-driven impact on your application.
Updated January 18, 2024.
Interaction to Next Paint (INP) measures your site’s responsiveness to user interactions on the page. The faster your page responds to user input, the better.
On March 12, 2024, INP will officially replace First Input Delay (FID) as the third Core Web Vital.
This post will help you understand why INP is a better way to measure responsiveness than FID and how React and Next.js can improve INP. You'll be prepared for updates to Core Web Vitals, which impact search rankings, as INP moves from experimental to stable. We have a separate post on understanding the metric and further optimization of INP.
Vercel Analytics now supports measuring Interaction to Next Paint (INP).
INP measures your site’s responsiveness to user interactions on the page. The faster your page responds to user input – the better. INP is an experimental metric to develop a better way of measuring responsiveness than First Input Delay (FID).
Try Vercel Analytics today to start measuring your performance.
Domains already in use can now be transferred directly to a new project on Vercel.
Previously, domains had to be removed from a project before being added to a new one. With this update, if you attempt to move a live domain to a new project, a prompt will appear offering to move the in-use domain and all associated redirects to the selected project.
Check out the documentation as well.
You can now use a total of 64KB in Environments Variables for each of your Deployments on Vercel. This change means you can add large values for authentication tokens, JWTs, or certificates, without worrying about storage size.
Deployments using Node.js, Python, and Ruby can support the larger 64KB environment.
Check out the documentation as well.
Hashnode, a blogging platform for the developer community built using Next.js, was born from the fundamental idea that developers should own the content they publish. A key component of that ownership is publishing articles on a custom domain—a feature the Hashnode team spent hours monitoring and maintaining themselves. That’s when they turned to Vercel.
Requests received by Serverless and Edge Functions are now enriched with headers containing information about the timezone of the visitor:
As an example, a request from Tokyo is now enriched with the following headers:
This header is now automatically activated for all new and existing Vercel Functions for all plans — no code or configuration change needed.
Check out the documentation as well.
It's now easier to visualize performance trends over time with Vercel Analytics.
Individual Core Web Vital data points are now displayed as a scatter plot with a trend line showing the estimation curve. This line is shown when there are more than 100 data points for the currently selected date and time window. The performance delta is calculated based on the estimation curve instead of the first and last data points for improved accuracy.

We believe the Web is an open platform for everyone, and strive to make Vercel accessible and available no matter how you choose to build for the Web.
Today we’re introducing the Build Output API, a file-system-based specification that allows any framework to build for Vercel and take advantage of Vercel’s infrastructure building blocks like Edge Functions, Edge Middleware, Incremental Static Regeneration (ISR), Image Optimization, and more.
Vercel’s Build Output API is now generally available. This API allows any framework, including your own custom-built solution, to take advantage of Vercel’s infrastructure building blocks including Edge Middleware, Edge Functions, Incremental Static Regeneration, Image Optimization, and more.
This specification also allows us to introduce two new commands to Vercel CLI:
vercel build: Build a project locally or in your own CI environment
vercel deploy --prebuilt: Deploy a build output directly to Vercel without sending source code through Vercel's build system
Read more about the Build Output API announcement on the blog. For framework authors, explore the Build Output API examples.
You can now set an expiration date on all newly created Access Tokens. Setting an expiration date on an Access Token is highly recommended and is considered one of the standard security practices that helps keep your account secure. You can select from a default list of expiration dates ranging from 1 day to 1 year. Expired tokens can be viewed on the tokens page.

With your feedback, we've shipped dozens of bug fixes and small feature requests to improve your product experience. Here are some of our most recent.
Vercel CLI: Vercel CLI v24.2.1 is now available, which includes support for Node.js 16.
Terms of Service (ToS): The Vercel ToS has been updated to provide additional information about what using a beta product or feature means.
Documentation improvements: The documentation for integrations now more clearly show how to use webhooks, Log Drains, and Checks.
Improvements for URL filters: When you select a time period on the usage tab, the filter is persisted in the URL which makes sharing that specific view with your team easier.
Design improvements for the usage tab: If limits have been exceeded on the usage tab, the color of the usage meter changes to better indicate the current state.
Project settings improvements: Transferring or deleting a project is now available on the general settings for that project.
Let us know other opportunities where we can improve your experience with Vercel.
As of today, version 16 of Node.js can be selected in the Node.js Version section on the General page in the Project Settings (newly created Projects will default to the new version).
The new version introduces several new features including:
ECMAScript RegExp Match Indices
AbortController
AggregateError
Array.prototype.at()
require('crypto').webcrypto
require('timers/promises')
fs.cp()
The exact version used today is 16.14.0 and will automatically update minor and patch releases. Therefore, only the major version (16.x) is guaranteed.
Check out the documentation as well.
If you host multiple subdomains on Vercel throughout separate accounts, you are now able to verify ownership of those subdomains in a self-serve manner via the Vercel Dashboard and API. Adding a subdomain to a project no longer requires the apex domain. Ownership is established via a token that is generated when the subdomain is added to a project and published in the domain owner’s DNS records. This change makes it easier to share domains for Platforms, teams, and collaborators on Vercel.
To learn more check out the UI docs or REST API docs to add a domain to a project and verify that domain if needed.
New and existing monorepos deployed to Vercel will experience faster builds.
Vercel now automatically caches node_modules recursively when installing dependencies during the build process. ENABLE_ROOT_PATH_BUILD_CACHE=1 will be set as a default environment variable on all new and existing monorepo projects. For large monorepos, this can decrease build times by minutes.
Check out the docs as well.
Following the release of Python 3.9, Vercel is deprecating support for Python 3.6 which reached end of life last year.

The largest software companies in the world use monorepos. But historically, adopting a monorepo for anything other than at a Facebook or Google scale was difficult, time-consuming, and often filled with headaches.
Since Turborepo joined Vercel, we’ve seen development teams of all sizes adopt Turborepo for faster builds and save over 200 days worth of time by remotely caching their deployments on Vercel.
Monorepo build systems like Turborepo are able to leverage Vercel's infrastructure to remotely cache build artifacts using our Remote Cache API. Turborepo uses this API out-of-the-box to store build artifacts and make builds more efficient.
This API is now available as a public beta. To learn more about using the Remote Cache API please read our documentation here.
When using monorepo build tools like Turborepo, Vercel automatically caches build artifacts remotely for faster, more efficient builds. The usage dashboard now highlights time saved for your team's projects using Remote Caching. You can visualize data based on whether the cache was local or remote, as well as per project.
Check out the documentation to get started with Remote Caching.
Enterprise customers can now transfer projects to other Vercel accounts.
This makes it easier for Enterprise teams to move projects between different accounts when ownership changes.

As previously mentioned (on May 25th, 2021) Vercel will be removing UI Hooks for integrations.
UI Hooks have already become unavailable for newly created Integrations, but they will also be removed from all existing Integrations, meaning that:
Integrations with UI Hooks can't be installed anymore.
Integration UI Hooks will no longer be shown on the Dashboard.
The respective configuration field will be removed from the Integration Console.
The API endpoint
/v1/integrations/configuration/:id/metadata
will become unavailable.
Furthermore, we also deprecated the manual webhook creation through our API. See our previous announcement about this change. This means that:
The API endpoint
/v1/integrations/webhooks
will become unavailable.
The API endpoint
/v1/integrations/webhooks/:id
will become unavailable.
DELETE
requests to the configured generic Webhook URL will be not send anymore.

Check out the documentation as well.
We’re happy to share that Vercel's new and improved Slack Integration is now ready for use.
It can be installed from the Integration Marketplace and comes with a number of advantages over the previous Slack Integration. You can now:
Choose specific events you’re interested in.
Send all events to one Slack channel or to multiple on a per-project basis.
Send events to private Slack channels.
If you're currently using the previous legacy Slack Integration (you can tell by opening the Integration's configuration view from your Personal Account or Team dashboard), please remove it and add the new one, as the legacy Integration will stop working on August 20th.
Furthermore, if you're using the legacy Integration, you will also receive a notification directly on your Slack channel about the next steps you can take to upgrade to its latest version.
Your Vercel dashboard provides you with an overview of Projects available within your Personal Account or Team, and what their status is.
Today we're excited to announce a completely overhauled dashboard overview with a number of improvements. You can now...
Search for a particular Project.
See which change is currently available in Production for your Projects.
Easily find the Project you're looking for by framework icon or favicon.

Vercel will now automatically detect whether your Project's dependencies were added with version 7 of the npm CLI, based on the presence of the latest lockfile format.
If detected, Vercel will automatically switch to using npm v7 to install your Project's dependencies within the Build Step.
This means that, among many bug fixes in the latest version of npm, your Deployments can now make use of the following new features:
Check out the full release notes and the documentation as well.
When importing a Git repository into Vercel, your Project's dependencies used to automatically be installed using either Yarn or npm, depending on your code. Selecting a different package manager such as pnpm was only possible after the Project was already deployed.
As of today, however, you can configure your custom Install Command even before the first Deployment for your new Project is created.
This also comes in handy for passing custom options to the yarn or npm install commands, since you can simply place the command of your choice in the "Install Command" field.
Check out the documentation as well.
Creating a new project on the dashboard now takes you through a new, simpler flow:
New projects will default to your currently selected Personal Account or Team, instead of prompting you to pick one every time.
Everything now happens on a single view, instead of making you navigate through four different pages every time.
These improvements make it easier to import a Git repository or start fresh from a Template. Try it out by clicking the New Project button on your dashboard!
If you'd like to integrate our new Project Creation Flow into your own application or Git repository, check out the documentation as well.
Vercel now automatically optimizes your SvelteKit projects. When importing a new project, it will detect SvelteKit and configure the right settings for you.

Vercel now automatically optimizes your Vite projects. When importing a new project, it will detect Vite and configure the right settings for you.
In addition, System Environment Variables are made available under the VITE_ prefix by default and you can now easily start new Vite projects from the dashboard.
Check out the documentation as well.
Enterprise Teams can now use their identity provider to log into and sign up to Vercel with SAML Single Sign-On. Popular identity providers such as Okta, Google, Auth0, OneLogin, and Azure are supported and can be configured in the Security section of your Team Settings.
For additional security, SAML can be enforced. This requires team members to authenticate with your identity provider for all interactions with the Vercel Team.
Lastly, the related Directory Sync feature allows Enterprise teams to automatically sync users from a directory provider (Okta, Google, Azure, and generic SCIM providers are supported), add or remove them from the Team, and issue Vercel Personal Accounts as needed.
Contact Sales to upgrade to an Enterprise plan, or check out the documentation.
To provide better insight into the amount of resources a project uses on Vercel, new functionality was added to the Usage Overview:
Additional presets for the date range, and the ability to select any start and end date, allowing for a better understanding of how your usage has changed over time.
Usage metrics can now also be filtered by individual Serverless Functions, allowing you to identify which Functions don't perform optimally.
A new chart for Image Optimization shows the number of optimized source images, to provide insight into how Image Optimization is used across your projects.

Today, we’re excited to announce Kathy Korevec will be joining our leadership team at Vercel as Head of Product!
The Integrations Marketplace has been upgraded. With an improved design, it's now easier than ever to discover and install Integrations in one place. All listed Integrations have been reworked to maximize usability and deliver a stellar user experience.
Check out the new categories of Integrations:
Check out our updated documentation to learn how to create your own Integration.
Today, we’re announcing our upgraded Integration Marketplace. We collaborated with partners to streamline installation and reduce as much configuration as possible, and gathered feedback from customers to increase visibility and confidence at every step of your development journey.
Today, we’re happy to announce our Series C funding. This is a major milestone for our company, customers, and community in our mission to build a faster web, together.
Last week, over 65,000 members of the Next.js community tuned in to watch a special edition of Next.js Conf where we shared our progress toward building a faster web.
Missed it? Here's what you need to know.
At Vercel, our goal is to provide you with the best performance for your web projects, while still allowing for the most flexibility possible when it comes to tailoring responses to users.
As part of these efforts, we're now launching a new sub property called has for rewrites, redirects, and headers (in vercel.json or next.config.js), which allows for routing conditionally based on the values of headers, cookies, and query string parameters.
Combined with features like SSG, ISR, or cached SSR, it can be used in cases like these:
Responding differently based on a cookie that was set in the visitor's browser (Cookie header) or the type of device the visitor is using (User-Agent header).
Responding differently based on the geographical location of the visitor (Geo-IP headers).
Redirecting users directly to their dashboard if they're logged in (Cookie header).
Redirecting old browsers to prevent serving unsupported pages (User-Agent header).
Check out the documentation and Next.js announcement to learn more.
The new Usage Overview on the dashboard that was recently added for Teams on the Pro and Enterprise plans is now also available for Personal Accounts on the Hobby plan.
It provides insight into the following metrics related to your own usage of the Vercel platform:
The Networking section helps you to optimize your Deployment's responses.
The Functions section lets you identify Serverless Functions that execute poorly.
The Builds section will help you improve the duration of your Builds.
The Analytics section provides information about how many Web Vital data points were collected for your Deployments.
Check out the documentation as well.
Since the launch of the Integration Marketplace, any newly submitted Integration was expected to provide UI Hooks for integrating its UI into the Vercel Dashboard.
As this constraint required a lot of additional work to be done by third-party services that already had their Integration UI available in their own dashboard, UI Hooks will now be deprecated in favor of allowing Integration authors to re-use existing interfaces outside Vercel.
UI Hooks have already become unavailable for newly created Integrations, but they will soon also be removed from all existing Integrations, meaning that:
Integration UI Hooks will no longer be shown on the Dashboard.
The respective configuration field will be removed from the Integration Console.
The API endpoint /v1/integrations/configuration/:id/metadata will become unavailable.
These changes will be applied on August 20th, 2021, which is the same date as the one that was announced for the Deprecation of old Integration Webhooks.
Check out the updated documentation to learn more about upgrading your Integration.
The following Dashboard pages now display the Environment of Deployments and Domains:
The Deployment View
The Deployment List
The Domain List in your Project Settings
In the case of Domains and Environment Variables, the Environment reflects the Environment of the Deployments that they're assigned to.
This change will make it easier for you to determine which Deployments, Domains, and Environment Variables relate to each other.
Check out the documentation as well.
If you receive a pull request from a fork of your Git repository that includes a change to the vercel.json file or the Project has Environment Variables configured, Vercel will require authorization from you or a member of your Team to deploy the pull request.
This behavior protects you from accidentally leaking sensitive Project information.
If you're certain your Environment Variables do not contain sensitive information, you can now disable Git Fork Protection by visiting the Security section of your Project Settings.
Check out the documentation as well.
You can now add Environment Variables to a specific Git branch in the Preview Environment.
When you push to a branch, a combination of Preview Environment Variables and branch-specific variables will be used. Branch-specific variables will override other variables with the same name. This means you don't need to replicate all your existing Preview Environment Variables for each branch – you only need to add the values you wish to override.
Also, you no longer need to specify the type of Environment Variable (Plaintext, Secret, Provided by System) because all values are now encrypted. The new design is optimized for both security and convenience, ensuring you can easily view the value later by editing in the UI or running vercel env pull to fetch Development Environment Variables locally.
We previously introduced the Provided by System option as some frameworks need to map system variables like VERCEL_URL to framework prefixed variables like NEXT_PUBLIC_VERCEL_URL. You no longer need to configure this mapping because the prefixed variables are added automatically based on your Framework Preset.
Check out the documentation as well.
You can now specify a generic Webhook URL in your Integration settings. If your Integration relies on Webhooks, it will now be much easier to configure and use them. Each of the following events will be sent as a POST request:
Deployment Created, Deployment Ready, and Deployment Error events can be sent for each Project your Integration is installed to.
Integration Removed and Permission Updated events can be sent for each Integration Configuration created by your Integration.
Project Created and Project Removed events can be sent when an Integration has access to all Projects in a Vercel scope, and a Project was created or removed in that scope.
It's been possible to manually list, create, and delete Webhooks via the Vercel API, but this API is deprecated and will be removed on August 20th, 2021.
We no longer support a Delete Hook URL that receives a DELETE request when an Integration Configuration was removed. If a Delete Hook URL was set, it is now set as a Webhook URL, and "Integration Removed" is turned on. At the moment, the Integration Removed event is sent as two events (a POST request and a DELETE request). The DELETE requests will no longer be sent starting August 20th, 2021.
Check out the updated documentation and API reference to learn more.
Beginning this June, Google will add Core Web Vitals to its Page Experience ranking signal. Google announced last year that changes were coming to the way its algorithm ranks pages that went beyond how quickly pages were loaded, safe-browsing, HTTPS, and their mobile-friendliness.
Core Web Vitals evaluate speed, responsiveness, and visual stability of pages and prioritize the site in rankings based on the outcomes of these scores. This means your site performance has a direct impact on SEO and your business.
Starting today, if you are looking to transfer out domains you purchased from or transferred into Vercel, you can access the authentication code for initiating the transfer to another registrar directly on your Domains overview.
Previously, this was only possible by contacting Support.
Check out the documentation as well.
Adding a domain to a project will now also suggest adding its www counterpart. This ensures visitors can always access your site, regardless of whether they type www when entering the domain, or not.
Using a www domain guarantees that the Vercel Edge Network can reliably and securely route incoming traffic as quickly as possible, so redirecting non-www to the www domain is recommended. Redirecting the other way works too if you prefer a cleaner URL address.
Existing domains are not affected by this change, but we recommend ensuring that your project already has a www redirect in place.
Check out the documentation as well.
To surface the default behavior and provide granular control, you can now find an option for including the build cache when redeploying an existing Deployment.
This update also comes with a refreshed UI for the redeploying functionality, which states more clearly which Domains will be applied to the new Deployment.
Check out the documentation as well.
The Build Step now considers the current Git branch when reading and writing the cache.
Since the first push to a branch will create a deployment without a branch-specific cache, it will read from the Production branch's cache. Subsequent pushes to that branch will read from its own branch-specific cache.
This means that Preview branches will no longer write to the Production branch's cache. This leads to faster builds because changing dependencies in one branch won't change the cache of another branch.
In addition, we no longer delete the build cache when a build fails. Instead, you can manually trigger a build without cache by using the "Redeploy" button on the Dashboard.
Our tests with a large Next.js app brought down incremental build times from 13 minutes to 4 minutes.
Check out the documentation as well.
Requests received by Serverless Functions on Pro and Enterprise Teams are now enriched with headers containing information about the geographic location of the visitor:
X-Vercel-IP-Country – The 2-letter country code of the IP sending the request.
X-Vercel-IP-Country-Region – The ISO 3166-2 region code associated to the IP.
X-Vercel-IP-City – The city name associated to the IP.
As an example, a request from Tokyo is now enriched with the following headers:
This feature is now automatically activated for all new and existing Serverless Functions on Pro and Enterprise Teams — no code or configuration change needed.
Check out the documentation as well.
Since the last Next.js Conf, we have expanded Vercel analytics offerings to include Next.js and Gatsby. Today, we expand that offering to include Nuxt analytics, providing developers with their Real Experience Score through data from actual visitors.
Today, we're announcing that every Git push and Vercel CLI invocation will result in a new unique URL and a new immutable Deployment.
Existing Deployments will no longer be re-used if you try to create a new one.
This change will likely not impact you in a meaningful way. On November 20th 2020, we enabled automatic System Environment Variables by default. If that option is enabled, a new immutable Deployment will already be created every time.
Vercel always strives to give you real-time feedback on every change you push. To this end, we are working on leveraging smart incremental computation techniques to avoid redoing work that’s already been done.
Vercel Analytics now updates your Real Experience Score in near real-time as visitors load your website:
Data is available seconds after enabling Analytics (down from ~30 minutes).
Immediately see updated metrics after new Production Deployment (down from ~3 hours).
Enjoy a reactive dashboard experience, even when viewing data for long time spans.
Improved search, loading, and sorting for Pages/URLs for better page-by-page analysis.
In addition to near real-time updates, you can now adjust the score interval granularity to help you understand your Real Experience Score better than ever before.
Enable Vercel Analytics for your project today, or visit the documentation.
Nuxt analytics are now available for all Nuxt projects on Vercel as part of Vercel Analytics, with zero configuration. This allows developers to understand the Real Experience Score for Nuxt projects.
To enable, after importing your Nuxt project:
Open a Nuxt project in your Vercel dashboard.
Select the "Analytics" tab and follow the flow.
No code changes are required, and options for self-hosted applications are available for enterprises.
Once deployed, your application will automatically report Core Web Vitals to Vercel.
Check out the documentation as well.
Starting today, Jekyll dependencies from bundle install will be cached and used for subsequent Deployments. A "hello world" Jekyll application now builds 15x faster – down from 3 minutes to 11 seconds with cache.
You can verify that the build cache was used by viewing your Deployment's build logs.
With the introduction of a new Usage overview, the dashboard now provides detailed insight into all the relevant usage metrics for your Team, and visualizes them as different charts:
The Networking section helps you ensure all responses are made as efficient as possible, split by cached and uncached responses.
The Functions section helps you track down misbehaving Serverless Functions through understanding requests that failed, timed out or were throttled.
The Builds section helps you ensure your Deployments spend the least amount of time possible in the Build Step.
Navigate to the new "Usage" tab available to Teams on the Pro or Enterprise plan and start optimizing your Projects today.
Check out the documentation as well.
Today, we are announcing an improvement to how usage metrics are delivered to developers and teams on Pro and Enterprise plans.
You can now select a temporary or permanent status code for Domain Redirects.
There are some subtle differences between these status codes:
307 Temporary Redirect: Not cached by client, method and body never changed.
302 Found: Not cached by client, method may or may not be changed to GET.
308 Permanent Redirect: Cached by client, method and body never changed.
301 Moved Permanently: Cached by client, method may or may not be changed to GET.
We recommend using status code 307 or 308 to avoid the ambiguity of non-GET methods, which is necessary when your application needs to redirect a public API.
Check out the documentation as well.
In the past year, we have enabled enterprise companies like Airbnb, Harry Rosen, and Coravin to develop better websites that deliver tremendous business impact. We didn’t do this alone. Vercel's partners helped to make these mission-critical transformations a reality.
Following the release of Node.js 14 last week, Vercel is announcing the deprecation of Node.js 10, which reaches its offical end of life on April 30th 2021.
On April 20th 2021, Node.js 10 will be disabled in the Project Settings and existing Projects that have Node.js 10 selected will render an error whenever a new Deployment is created. The same error will show if the Node.js version was configured in the source code.
Serverless Functions of existing Deployments that are using Node.js 10 will be migrated to Node.js 12 on the date mentioned above.
If your Project is using Node.js 10 (which you've either defined in engines in package.json or on the General page in the Project Settings), we recommend upgrading it to the latest version (Node.js 14).
Need help migrating to Node.js 14? Let us know and we'll help you out.
Last month, Vercel announced that the Directory Listing feature could now be toggled directly from the Project Settings and that it would be disabled for newly created Projects.
In favor of security, and to prevent unexpected behavior for older Projects, the Directory Listing feature will be disabled for all Projects that were created before January 12th 2021, which is the release date of the respective Project Setting.
The change will be applied on March 8th 2021.
Because the Directory Listing feature allows for accessing the source code of a Deployment if no index file is present within it, it's safer to disable it by default. If you want, however, you can turn the feature back on right afterwards, if you're relying on it.
Check out the documentation as well.
As of today, version 14 of Node.js can be selected in the Node.js Version section on the General page in the Project Settings (newly created Projects will default to the new version).
Among other features, the new version introduces Diagnostic Reports, which can be logged to Log Drains (recommended) like so:
The following features were introduced through v8:
The exact version used is 14.15.4 (changelog), but automatic updates will be applied for new minor and patch releases. Therefore, only the major version (14.x) is guaranteed.
Check out the documentation as well.
At the moment, the URLs of incoming requests to Python Serverless Functions deployed on Vercel are decoded automatically.
Because this behavior is not consistent with a "standalone" Python server, Vercel will stop decoding them for newly created Serverless Functions starting March 2nd, 2021. Existing Deployments will not be affected.
As an example, take a look at the Python Serverless Function code shown above and imagine that the URL of the incoming request ends in /hi%21:
With the incorrect behavior, self.path will be set to /hi!.
With the updated correct behavior, self.path will be set to /hi%21, which matches the behavior of the built-in HTTPServer class in Python.
To try out this change, define a FORCE_RUNTIME_TAG Environment Variable for your project, set it to canary and create a new Deployment.
There is a new way to transfer projects on Vercel from Hobby accounts to Team plans or between two different Teams with zero downtime. This means Teams no longer need to redeploy projects that were deployed under a Hobby plan or a different Team.
Personal Accounts on Vercel are great for hobby projects. Once you need to deploy more powerful sites, collaborate with other people and customize your workflow, Teams are the right way to go.
Migrating from a Personal Account to a Team previously wasn't possible without incurring downtime. It required removing Projects from their old location and deploying them again in the new one. As of today, it's only a matter of a few clicks on the dashboard.
Transferring projects without downtime is now as easy as navigating to the Advanced page in the Project Settings, following the flow and watching the magic happen.
All Deployments, Domains, Environment Variables, and any other configuration of your Project will automatically be moved to the target Team for you. Even optional features you might've enabled can be transferred over.
Check out the documentation as well.
Here are 10 little known Next.js tips you might not have heard that could help you save time on your next project:
For easy customization and in preparation for Node.js 14 LTS landing in the future, the General page in the Project Settings now contains a section for defining the Node.js version used in the Build Step and Serverless Functions.
Previously, defining an engines property in the package.json file was required to customize the Node.js version. However, this property will take precedence over the Project Setting.
Check out the documentation as well.
Invoices for your payments on Vercel were previously found in the Past Invoices section of the Usage tab in the Dashboard.
To make it easier to navigate, they have been moved to a dedicated Invoices page alongside Billing in the Personal Account and Team Settings.
Even though the Upcoming Invoice section has been removed with this change, the Billing page in the Personal Account and Team Settings now provides the same insight.
A lot of feedback we've gathered has shown that the URLs Vercel currently provides you with are too complicated. As part of our strategy for making them simpler, we're starting with applying a consistent format on February 20th 2021:
Custom Domains and Automatic URLs ending in now.sh will instead end in vercel.app.
Automatic Deployment URLs like project-d418mhwf5.vercel.app will gain the slug of the owner Vercel scope to match Automatic Branch URLs: project-d418mhwf5-team.vercel.app.
Automatic Branch URLs like project-git-update.team.vercel.app will lose their second subdomain level in favor of a dash: project-git-update-team.vercel.app.
Automatic Project URLs like project.team.vercel.app and Automatic Team Member URLs like project-user.team.vercel.app will be adjusted like Automatic Branch URLs.
It is recommended to not rely on any of the Automatic URLs for Production use cases and instead use Custom Domains for that. If that's not possible, please ensure any program sending requests to these URLs supports 308 redirects – like modern browsers do.
React Server Components allow developers to build applications that span the server and client, combining the rich interactivity of client-side apps with the improved performance of traditional server rendering.
In the upcoming Next.js major release, React developers will be able to use Server Components inside the app directory as part of the changes outlined by the Layouts RFC. This post will explore how Server Components will enable developers to create faster React applications.
Many Serverless Functions communicate with third-party services. Because most of these services are available in the US East region, deploying Serverless Functions to US West leads to slower response times.
For that reason (and to decrease the latency for requests arriving from Europe), newly created projects will default to the US East region (Washington, D.C., USA) instead of US West (San Francisco, USA) when deploying Serverless Functions.
Existing projects will be unaffected, but can be switched to the new default from the new "Serverless Functions" page in the Project Settings.
Check out the documentation as well.
If a payment had failed for your Team because of an issue with your payment method, you previously had to reach out to our Support Team and ask them to retry it, so that you could create Deployments again.
Since that's quite a slow process, we instead added a button to the Billing page in your Team Settings that you can click to immediately issue a new charge. If that charge succeeds, your Team will be able to create Deployments again right after.
Changing the payment method will automatically issue a charge too, so this button is particularily helpful if you've fixed an issue with an existing payment method.
Until now, directories used to list the directory's contents whenever their path was visited (provided they didn't contain an index file).
In cases where this was considered a security issue, turning off the Directory Listing required configuring a rewrite rule in vercel.json.
As of today, the Directory Listing is disabled for all newly created Projects and can be toggled on the "Advanced" page in the Project Settings.
Check out the documentation as well.
Importing a Git repository into Vercel used to require navigating to it on the Git provider of your choice, copying its URL from the address bar, pasting it in the project creation flow on Vercel and then following the steps.
Thanks to its most recent update, however, the project creation flow now renders a list of recommended Git repositories to import and allows for searching for a particular one as well, annotated with icons for the frameworks that are being used within those Git repositories.
Cloning a Template is now also much easier than before, as they are presented on the same page as the recommended Git repositories.
Check out the documentation as well.
When connecting a Project on Vercel to a Git repository, the Git repository previously had to be located in the same Git scope as the Git repositories of all other Projects within that Personal Account or Team.
Now that this connection is defined on the Project-level (see above) instead of being configured on the Personal Account or Team, this limitation is lifted. Additionally, problems with an active connection are now surfaced there too.
Every Personal Account or Team can now contain Vercel Projects that are connected to Git repositories located in various different Git scopes. This also means that, when importing one, Vercel no longer forces a certain destination Personal Account or Team.
Check out the documentation as well.
Previously, Environment Variables defined in the Project Settings used to be sharded into different Environments using tabs in the UI. To make it easier to add them to multiple Environments at once and edit them like that, however, they now live in a single list.
In order to make it easy for you to still only view the Environment Variables you're interested in, we just added a new search field and a select field on the right that lets you filter the Environment Variables down to a specific Environment.
Projects are core to everything on your Vercel account. We’ve recently improved the developer experience by introducing three updates for projects. These apply to all users on Hobby, Pro, and Enterprise plans.
By improving how projects are created and connected to Git in Vercel, we expect a decrease in the time between project creation and deployment for all users and a reduction in complexity for some larger Vercel customers.
Today, we announce $40M in new funding to help everyone build the next web.
When responding to investors, we told them the stories of our customers, from independent developers to Fortune 10 companies, and the lessons we learned this year about how Next.js and Vercel help teams collaborate and move faster with greater flexibility.
If the logs that your source code or your framework are exposing within the Build Step or within your Serverless Functions contain ANSI color codes for providing more clarity, Vercel previously directly printed them out in the respective views on the Dashboard.
As of today, however, all of those codes are automatically parsed within the Deployment View, which contains Build Logs on the main page, but also the logs for your Serverless Functions on the "Functions" tab.
In the example above, you can see that ANSI codes are now automatically rendered as the colors they are supposed to represent, which makes the text much easier to understand.
Previously, consuming values provided by the Vercel platform in your Environment Variables (like the URL of your Deployment) required adding System Environment Variables using the "Environment Variables" page in the Project Settings.
All new Projects created as of today, however, will automatically receive all System Environment Variables by default – without you having to expose them explicitly.
This setting can also be controlled from existing Projects, which means that you can easily opt into the new behavior for those as well.
Furthermore, the available System Environment Variables were revamped to have much more straightforward names and don't differentiate between Git providers anymore. For example, you can now use VERCEL_GIT_COMMIT_REF to retrieve the Git commit SHA for GitHub, GitLab and Bitbucket instead of having to use several different System Environment Variables for that.
Check out the documentation as well.
For all the Projects you've deployed on Vercel in the past, the platform either automatically selected a name for you based on the name of your Git repository or local directory, or you manually customized it before the Project was created.
Previously, it wasn't possible to change the name of a Project after it was created. As of today, however, you can do it directly from the "General" page in the Project Settings.
When changing the name of your Project, no interruptions in your or your Team's workflow will occur, considering that you're either deploying from a Git repository or you've linked the Project to a local directory using Vercel CLI.
Check out the documentation as well.
By default, Vercel automatically determines the right command for installing your project's code dependencies in the Build Step based on the Framework Preset configured for your project and the presence of certain files (like package-lock.json) in your source code.
As of today, you can customize the command that Vercel will run within the Build Step for installing your code dependencies.
In the new Install Command section within the Project Settings, you can now enter any command of your choice that will be run instead of having Vercel automatically determine the right one for you.
Check out the documentation as well.
Once you've purchased a Domain with Vercel or transferred it in from a different platform, Vercel will automatically make sure that your Domain is renewed every year – before it expires.
Like this, you never have to worry about your projects becoming unavailable. Instead, you will automatically be charged the renewal fee every year and your Domain will continue working.
Previously, the only way to prevent a Domain from being renewed again (in the case that you don't want to continue using it, for example) was contacting our Support Team, who disabled auto renewal for you.
As of today, you can toggle the auto renewal behavior of a Domain right on the Dashboard by navigating to the "Domains" tab on your Personal Account or Team, clicking the Domain you're interested in and toggling the option on the top right.
Check out the documentation as well.
At Next.js Conf, we announced Next.js Analytics, providing developers with their Real Experience Score through data from actual visitors. Today we're expanding Vercel's analytics offerings to include Gatsby.
Vercel now supports monorepos for improved flexibility at scale. From the same Git repository, you can set up multiple projects to be built and deployed in parallel.
Monorepos let your team use multiple programming languages and frameworks, collaborate better, and leverage microfrontend architectures.
Learn more about how monoreops are changing how teams build software.
Vercel was born to help frontend teams succeed at scale. From the ideal developer experience on localhost, to the best performance for your end-user via our Global Edge Network.
Today we are introducing major end-to-end enhancements, starting with a realtime developer workflow (with Next.js and Vercel CLI) and finishing with serving pages up to 6x faster.
Up until now, after creating a new Project from a Git repository or one of our examples, all commits to its default branch were being deployed to Production.
Today we are introducing a new default for newly created Projects, as well as an easy way to customize it from your Project Settings.
Applying custom DNS Records to your Domains (for receiving emails, for example) has so far always required interacting with our advanced command-line interface.
From today, you'll be able to manage them directly from the Web UI and even insert presets for commonly used DNS Records.
Pushing a change to your project results in a Preview Deployment. Then, once you're ready, merging it into master results in a Production Deployment with the domain of your choice.
Even though Preview Deployments receive a unique URL, they might still be accessed by anyone that finds out about the URL. Today, we're introducing two features for easily protecting them right from the Dashboard.
If you are working on a sophisticated project, you might have found yourself wanting to configure different Environment Variables depending on the Environment your project is deployed to.
With today's release, we're making it possible to configure different Environment Variables for Production, Preview, and Development – right in the Dashboard.
Since the launch of our platform, we have always aimed to make our pricing model as simple as possible, and perfectly tailored to your needs.
Today, we are taking a giant leap towards that goal by introducing our new pricing plans for your personal account and teams.
As a remote-first company, we're lucky to be minimally affected by recent events. Outside of our regular work, we're doing our best to support one another and our families — hosting virtual game nights, zoom hangouts, group meditation, and regular check-ins.
We also recognize that we have an opportunity — no, an obligation — to help our communities in any way we can. So today, we want to step aside from our typical product-focused content and highlight some recent projects from developers in our Next.js and Vercel community.
Our community has built 2,500+ COVID-19 related sites generating over 150 million requests in the past 72 hours — providing critical information and awareness, helping prevent further outbreaks, and giving us tools for keeping each other safe. This blog post is dedicated to these inspiring efforts.
Sometimes you might find yourself having created a deployment that you don't need anymore, or that is causing other deployments to get queued behind it.
Previously, it was necessary to wait for such deployments to complete, and then delete them. As of today, however, you can immediately cancel deployments if they are no longer required.
Creating a new project on Vercel is as simple as importing a Git repository from your favorite provider, whether that's GitHub, GitLab, or Bitbucket.
Once a project has been imported, the Git Integration connection can be edited in the blink of an eye. Today, we're making this process easier to understand and more reliable than before.
With the launch of Log Drains, we made it easy to pipe the invocation logs of your Serverless Functions or Static Files to a log inspection tool like LogDNA or Datadog.
Handing off this piece of your production workflow to a service dedicated to this purpose allowed us to tighten our focus around what we do best: Plug-and-play realtime logs.
With the launch of Zero Config Deployments, we made setting up your projects as easy as importing a Git repository, and having every push and pull request deployed with Vercel. No configuration.
Today, we're extending this process to non-JavaScript projects (like Hugo sites) and giving you full control over your project's automatically configured settings.
Getting in touch with Vercel Support has always been straightforward. However, we wanted to make this even easier, providing direct access to Vercel Support from your dashboard and reducing the impact on your workflow. We are delighted to say that from today this is now possible, with the new Support Form.
Inspecting logs for the Build Step, Runtime, and Edge Network traffic of a deployment can be crucial to pinpointing aspects of its behavior and understanding better where improvements can be made.
Today, we are thrilled to announce support for Log Drains: collect all of your logs using a service that specializes in storing app logs.
2019 has been an incredible year for Vercel. We announced zero-config, launched a new integrations platform, and even hosted a successful hackathon.
To end the year on a memorable note, we held our first-ever remote conference: backendlessConf_.
After editing your project, previewing your changes with Vercel is only a matter of pushing a Git commit using our Git Integration, or by running a single command using our command-line interface.
Every Deployment created in either way receives a unique URL, yet you still might want to apply a Custom Domain for your Preview Deployments. Today, we are making this possible with Branch Domains.
Bitbucket is popular among teams as the central place to plan projects, collaborate on code, test, and deploy — especially in combination with Jira and Trello.
Today, we are proud to announce our first-class Bitbucket integration, Vercel for Bitbucket.
With the launch of Zero Config Deployments, Vercel made it easier than ever to deploy websites and applications. Now, we're bringing the simplicity of our developer experience to our web dashboard.
Creating new projects, importing existing code, managing domains, setting up redirects, inspecting deployments and functions, and managing teams has never been easier.
We are unveiling the next evolution of the Vercel Dashboard.
As the author of an open source project or framework, one of your key focuses is making it as easy as possible for users to get started with your creation.
With the help of today's feature release, you can now reduce this entire process down to the click of a single button: The Vercel Deploy Button.
After deploying a static frontend to Vercel, some projects might make use of Serverless Functions to feed data from.
Creating Serverless Functions is as simple as adding an API directory in your project, and today inspecting them became just as comfortable with the new "Functions" tab from your Deployment Overview.
When extending your project with Serverless Functions, you might find yourself in a situation where adjusting the default behavior is necessary.
Today, we are adding a new functions configuration property to allow you to do just this.
When creating a new project, it's important that the road to sharing a working production URL of your newly deployed code is as short as possible, with the least amount of friction.
With today's announcement, we're ensuring exactly that.
With Vercel, you can already deploy to HTTPS-enabled subdomains of your choice.
What if you could let customers choose those subdomains (like with Slack workspaces)? Today, we're making this possible with the introduction of Wildcard Domains!
Today, we're introducing Deploy Summary, a Vercel integration to augment your workflow with our GitHub and GitLab integrations even further.
Deploy Summary analyzes your pull requests and merge requests, detects changed pages, and provides a detailed preview right next to your commits:
Few weeks ago, we introduced Vercel as the most powerful and scalable platform for static websites and serverless functions powered by any language or framework.
This came at the expense of writing vercel.json files. Today, we are introducing Zero Config, a conventional and completely backwards-compatible approach to deployment.
Thanks to our first-class GitHub and GitLab Integrations, you can simply push your code to deploy with Vercel. But what if you wanted to create a deployment not based on change of source code, but another external event, such as an update in CMS content?
Starting today, you can deploy based on any event with Deploy Hooks.
With the release of Node.js 10, features like BigInt, a stable API for native addons, and several performance improvements have found their way into production.
Today, we are enabling Node.js 10 support for new serverless Node.js functions and Next.js applications deployed using Vercel.
Migrating to serverless Node.js functions or creating new ones can mean that some of the tools and frameworks you used previously are not suitable anymore.
With today's feature release, we want to solve this problem by providing you with a set of default helpers exposed within your Node.js function.
We kicked off June with the first-ever Vercel Hackathon, focused on creating integrations.
The event was a phenomenal success. Over 250 participants joined us from every corner of the world to submit high quality integrations that improve their workflow. After much deliberation, our judges finally have the results, and we are thrilled to announce the winners.
Static websites are fast. When you deploy static frontends to Vercel, we automatically serve them from every edge of our global Smart CDN network.
But static websites are also... static. Static site generators create all your pages during the build process — all of them, all at once. Ever had to quickly fix a typo in a page, only to wait minutes or hours for your change to go live?
Today, we are introducing Serverless Pre-Rendering, an industry-defining feature of our Smart CDN network that allows you to get the best of both worlds: the speed and reliability of static, and the versatility of dynamic data rendering.
Our Vercel platform enables you to deploy modern websites and applications without needing any complicated server configuration. Not only do we automatically configure DNS records for your domain, we also instantly issue and renew free wildcard SSL certificates, completely hands-free.
Historically, companies have spent thousands to get their websites HTTPS-enabled. Not to mention the whole process of issuance, download, re-upload, reconfigure, restart server with downtime — it's always enormously stressful and requires significant engineering resources.
When you connect your GitHub organization to Vercel, with Vercel for GitHub, we build and deploy your app for each every Git push. We call such an event a job.
For a given branch, we process each job in a queue. If multiple jobs are waiting, we pick the latest one to build. Vercel for GitHub will always give you the deployment URL for the most recent commit.
We are proud today to introduce the production-ready Next.js 6.1, featuring:
This year, the ZEIT Day Keynote started by highlighting our Open Source projects including showing the metrics of Next.js. With over 25000 stars on GitHub and over 10000 websites are already powered by it, we're incredibly amazed at its growth and love seeing the increasing amount of projects depending on it.
We are happy to introduce Next.js 5.1, which features support for environment configuration, phases, source maps, and new Next.js plugins.
Major performance improvements are introduced: resolving pages is 102x faster, and error pages are loaded more efficiently.
We are very happy to introduce Next.js 5.0 to the world. It’s available on npm effective immediately.
On the heels of the announcements of canary releases for Hyper, Now CLI, and Now Desktop, we are glad to announce the immediate availability of a canary channel for Next.js.
In addition, we are excited to share some of the goals we are currently working on towards the release of Next.js 5!
We are happy to introduce Next.js 4, which features support for React 16 and introduces a major upgrade for the default styling engine styled-jsx with support for dynamic styles.
We are very excited excited to announce the stable release of Next.js 3.0. Ever since our beta announcement, we have been using it to power vercel.com and have received lots of feedback and contributions from our community.
Let’s walk through what’s been improved and what’s altogether new, or fetch the latest version from npm!
New to Next.js? Next.js is a zero-configuration, single-command toolchain for React apps, with built-in server-rendering, code-splitting and more. Check out Learn Next.js to get started!
