Vercel Daemons now support HTTP liveness checks
Vercel Daemons now support configuring HTTP liveness checks. A daemon exposes an HTTP health endpoint, and its configuration accepts a livenessProbe value pointing to that endpoint; Vercel periodically requests the endpoint and restarts the daemon's container when the check fails.
Why it matters
Builders running long-lived background processes on Vercel can now have the platform detect and recover daemons that are still running but unhealthy, rather than relying on process exit alone.
Who should care
Developers and teams deploying background workers or long-running daemons on Vercel
What you can do
Add a lightweight HTTP health endpoint to your daemon that returns an error status when unhealthy, then reference it with livenessProbe in the daemon configuration (see the Daemon documentation for defaults and tuning fields).
