Vercel's CDN now supports updating routing rules without a new deployment

You can now create and update routing rules within a project, such as setting response headers or rewrites to an external API, without building a new deployment.

Project-level routing rules are available via the dashboard, API, CLI, and Vercel SDK and take effect instantly after you make and publish the change. Project-level routes run after bulk redirects and before your deployment config's routes.

With this addition, Vercel's CDN now supports three routing mechanisms:

• Routes defined in your deployment configuration (via vercel.json, vercel.ts, or next.config.js)

• Bulk redirects

• Project-level routes

Project-level routes are available on all plans starting today. Read the documentation or go to the CDN tab in your project dashboard to get started.
