You can now deploy FastHTML projects to Vercel with zero configuration.
FastHTML is a new Python framework for fast, scalable web applications with minimal, compact code. It builds on top of popular foundations like ASGI and HTMX.
The free tier can now run Vercel Functions 6x longer, up to 60 seconds. This is beneficial for streaming responses, especially when building AI applications.

Follow us to track how we work constantly to make Vercel better with your feedback.
Skew Protection—a novel mechanism to eliminate version skew between web clients and servers.
Now generally available for paid plans. Supported by Next.js, SvelteKit, and more frameworks soon.
Introducing the Jira integration for Vercel.
Comment, review, and share feedback with your team on deployments. Then, instantly convert the conversation into a Jira issue.
Node.js 14 and 16 are being deprecated on August 15, 2023.
While existing deployments with functions will not be affected, we encourage updating to Node.js 18.
Speed Insights now shows which HTML elements are affecting vitals, including:
◆ Interaction to Next Paint (INP)
◆ Cumulative Layout Shift (CLS)
◆ Largest Contentful Paint (LCP)
◆ First Input Delay (FID)
Vercel Blob allows you to upload and store images, videos, and other files.
You can now more easily manage files from the dashboard, including support for drag-and-drop and bulk uploads.
You can now use the Vercel Toolbar in production through a Chrome extension or npm package.
This allows your team to comment, toggle feature flags, measure iteration timing, and more—directly on your production domain.
You can now create new deployments directly from the dashboard by git branch or SHA.
This approach is helpful when git providers have service interruptions with webhook delivery.
It's now possible to configure the region for Serverless Functions in your Project Settings. Additionally, new Projects will default to US East instead of US West.
You can now use `waitUntil` with Vercel Functions.
This allows you to do non-blocking work, keeping the function alive until it's finished.
This works with any framework or runtime on Vercel.
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%.
Block, rate limit, and challenge traffic with the Vercel Firewall.
Rules can be based on 15+ fields including request path, user agent, IP address, JA4 fingerprint, geolocation, HTTP headers, and even target path.
Available on all plans for free.
Vercel Functions now scale 12x faster for high-volume requests on paid plans:
◆ Default concurrency quota increased to 30,000
◆ Scale out by 1,000+ concurrency every 10 seconds
◆ Ideal for unpredictable traffic or flash sales
Vercel will now automatically skip builds for unchanged code in your Turborepo or Nx monorepo.
This reduces build queuing and works with any monorepo tools using workspaces.
You can now easily run e2e 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`.
Vite-based frameworks such as SvelteKit, Remix, Nuxt, or Astro can now more easily integrate with the Vercel Toolbar.
The Toolbar enables you to comment on deployments, toggle feature flags, view draft content from a CMS, and more.
Vercel CLI v24 is now available:
◆ New `vercel bisect` command for deployment introspection
◆ Support for `--project` flag in `vercel link`
◆ `vercel dev` is now stable
◆ Refactored source code to TypeScript
We've made it easier to configure builds to:
◆ Only build for production
◆ Only build for preview
◆ Only build when your Turborepo changes
◆ Run a script
And more!
Introducing the GitHub integration for Vercel comments. Instantly convert feedback from teammates into GitHub Issues.
This joins our other comments integrations for Slack, Linear, and Jira.
Speed Insights helps you understand application performance. We've now improved the experience to include:
◆ Support for all frontend frameworks
◆ First-party data ingestion
◆ Time to First Byte (TTFB) tracking
◆ UI improvements & more
