Health Checks

Expose a health endpoint for worker liveness and readiness probes.

Health checks verify that a worker is healthy, including its connection to the Rivet control plane.

Mount registry.routes.health() in your HTTP router. For example, with Hono: app.get("/health", () => registry.routes.health()).

A healthy worker returns 200 with its status, runtime, and version. If its connection to the control plane is unhealthy, it returns 503. Point your liveness and readiness probes at the mounted path.
