Files & safety

Reading the source, version history, restoring a run, the security audit, and downloads.

1. 01Browsing the sourceThe Code tab shows every file in your app. It is read-only on purpose, and there are three limits worth knowing before you rely on it.
2. 02Version history and restoringEvery file the builder touches is recorded before and after. Any run can be rolled back — and the rollback is itself a run you can roll back.
3. 03The security checkSeven checks read your app's source for the mistakes that actually cause harm — bundled secrets, an open admin route, entitlements the browser can set. Running it is free.
4. 04Downloading your appThe whole project as a zip, any time, with no conditions. It is a standard Next.js app and it runs anywhere Node does.
