Learn how to configure the runtime, region, maximum duration, and memory for Vercel Functions.

The Edge Runtime is a toolkit for developing, testing, and defining the runtime Web APIs for Edge infrastructure.

Node.js version 22 is available as the runtime on Vercel for your builds and functions leveraging Node. Node 22 brings improved Stream performance, improved AbortSignal performance, improved Buffer performance, and improved CJS interoperability with ESM.

Streaming is now enabled by default for all Vercel Functions using the Python runtime. Python functions can now send data to the client as it’s generated, rather than waiting for the entire response—particularly useful for AI and real-time applications.

The runtime log limits for Vercel Functions have been increased, allowing for significantly larger log entries. Logs are increased to 256KB per log line, 256 log lines per request, and 1MB total log size per request.

Next.js 15.2 introduces experimental Node.js Middleware, now available at Vercel—giving you full Node.js runtime support for your Middleware. Run authentication, logging, request handling, and more with familiar Node.js APIs.

You can now filter your runtime logs to identify fatal function errors, such as Node.js crashes, in the Vercel Logs UI.

The Edge runtime now runs on Vercel Functions, unifying pricing across all compute, and available before and after cache. Edge Middleware and Edge Functions are now deprecated.

You can now run commands with sudo inside Vercel Sandbox, giving you full control to install packages at runtime, just like on a traditional Linux system.

Vercel RuntimeCache API that's available in all runtimes, including build, edge, middleware, & serverless.

Observability Plus subscribers now get 30 days of runtime log retention in the Logs page within the Vercel dashboard

The Bun runtime is now available in Public Beta for Vercel Functions. Benchmarks show Bun reduced average latency by 28% for CPU-bound Next.js rendering compared to Node.js.

Vercel Functions now supports the Bun runtime, giving developers faster performance options and greater flexibility for optimizing JavaScript workloads.

Vercel now supports Node.js 24 for builds and functions, featuring a V8 13.6 upgrade, the global URLPattern API, Undici v7 for faster fetch(), and npm v11 for modern package compatibility.

End-to-end performance of Vercel's log pipeline is now six times faster due to engineering improvements

You can now view rewrites and redirects made by your application in the Vercel dashboard on Runtime Logs

You can now view the referer for any request listed in the runtime logs page on the Vercel dashboard
