## AI overview

Node.js 20 will be deprecated for Builds and Functions on October 1, 2026. Existing deployments continue to run, but new deployments using Node.js 20 must upgrade or use a container image.

## Source excerpt

Following the Node.js 20 end of life on April 30, 2026, we are deprecating Node.js 20 for Builds and Functions on October 1, 2026. How can I see which of my projects are affected? You can see which of your projects are affected by this deprecation with: Will my existing deployments be affected? No, existing deployments with Serverless Functions will not be affected. Invocations to already-deployed functions will continue to work normally. Only new deployments will be affected. When will I no longer be able to use Node.js 20? On October 1, 2026, Node.js 20 will be disabled in Project Settings. Existing projects using 20 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. You can also hand the upgrade to your coding agent: What if I can't upgrade before October 1? If you can't complete the upgrade in time without disrupting your app, deploy it as a container image instead. Add a Dockerfile.vercel at your project root and the image is built and deployed on every commit: We still recommend upgrading when you can. With a container, you manage the Node.js version and its security updates yourself. Upgrade before October 1, 2026. Learn more about supported Node.js versions. Read more
