Vercel CDN adds hot-swap routing rules without new deployments
Project-Level Routing Now Available
Vercel has launched a new feature enabling developers to manage routing rules at the project level without requiring a new deployment. This means you can now update response headers, rewrites, redirects, and other routing logic on the fly—changes take effect instantly after publishing.
How It Works
Project-level routing rules integrate seamlessly into Vercel's existing CDN routing stack. The execution order is:
- Deployment configuration routes (defined in
vercel.json,vercel.ts, ornext.config.js) - Project-level routes (new feature)
- Bulk redirects
Access this feature through multiple interfaces:
- Dashboard: New CDN tab in your project settings
- API: Programmatic routing management
- CLI: Command-line configuration
- Vercel SDK: SDK-based management
Key Benefits
- Zero downtime: Update routing logic without redeploying your application
- Flexibility: Adjust response headers, rewrites to external APIs, and redirects on demand
- Universal availability: Project-level routes are available on all Vercel pricing plans, from free tier to Enterprise
