Is it safe to delete build folders?

Rebuilds automatically Yes.

Files the project's build produced (JavaScript, Gradle or Flutter). Rebuilt on the next build.

Where it is

What “Rebuilds automatically” means

The app or tool that made it recreates it by itself the next time it's needed. Removing it only costs a little time. ClearMac pre-selects these items.

How ClearMac handles it

ClearMac pre-selects it in a cleanup and moves it to the Trash, so you can put it back until you empty the Trash.

This page is generated from the same rule ClearMac uses on your Mac (project.build-folder), so the app and this page always say the same thing.
