Scale to Zero

Scale-to-zero sleeps idle apps so they stop using compute.

How it feels

An idle app may take a little longer to answer the first request because it has to wake up. After that, requests should be normal.

Sleeping apps do not accrue running compute charges. They may still have other charges, such as domains, databases, or build minutes.

Apps that keep receiving traffic stay warm. Background work, frequent pings, or long-lived connections can prevent sleep.

If you run dock stop, the project is stopped intentionally and does not wake on the next request. Use dock start to run it again.
