Keep your app warm

Skip idle sleep on Pro so your app answers instantly.

Keep-warm is a Pro feature. Flagged fleets skip idle sleep, so the first request never pays a cold start.

1. Open Console → Settings.
2. Turn on Keep warm.

Turn it off any time, on any plan.

The host holds a cap on warm fleets: past the cap, the longest-idle warm fleet sleeps. Build detail lives in Follow the deploy pipeline.
