Vercel Daemons Add Support for HTTP Liveness Checks

·2026.10.30 09:00

Key point

The feature allows users to configure a lightweight health endpoint that triggers a container restart if the daemon fails the periodic check.

Details

  • Vercel Daemons now support configuring HTTP liveness checks to monitor daemon health.
  • Users must implement a lightweight HTTP endpoint that returns an error status when the daemon is no longer healthy.
  • The daemon configuration accepts a livenessProbe value pointing to the health endpoint.
  • Vercel periodically requests the endpoint and restarts the daemon's container if the check fails, catching daemons that are running but unhealthy.
  • Documentation provides details on default values and optional tuning fields for liveness checks.
