Scale to Zero

Free-tier services automatically sleep when idle and wake on the first request.

How It Works

Services on the Free plan are monitored for activity
After a period of inactivity (no HTTP requests), the service is scaled to 0 replicas
When a new request arrives, RailPush shows a branded wakeup page while the service starts (~30-60s cold start)
Once healthy, traffic is routed normally -- subsequent requests are instant
Custom domains also trigger wakeup correctly

Opt Out

Upgrade to any paid size (S, M, L) to keep your service running 24/7. Paid services are never auto-scaled to zero.
