Vercel Daemons Support Service Bindings for Private Internal Calls

·2026.10.30 09:00

Key point

The feature handles internal routing, authentication, and TLS while keeping target services private.

Details

  • Vercel Daemons can now call services within their deployment using service bindings.
  • Bindings are declared on the daemon, naming the target service and the environment variable that receives the service's URL.
  • Vercel manages internal routing, authentication, and TLS, ensuring the service remains private.
  • Bindings are one-way; services cannot bind to daemons.
  • Each daemon instance continues calling the deployment that started it, even after a promotion or rollback.
