# Pull request previews

Every open pull request gets its own running copy of the app at a deterministic URL, posted as a comment on the pull request and torn down when it closes. Previews can run on a cheaper server than production.

## Built for strangers' code

A preview from a fork never receives a secret-typed variable and waits for a human to approve it. It runs in a sealed network of its own, so it cannot reach your database. Over the limit, the oldest preview is stopped, not deleted, and Redeploy brings the same URL back.
