Project-specific Derived Data

View the Derived Data size for each individual project and selectively clean only what is needed without losing all builds.

Simulator runtimes

Identify obsolete simulator runtimes downloaded by older Xcode versions and delete them easily to retrieve gigabytes of space.

Sandbox security

Using Apple's Folder Bookmarks, BuildBroom runs safely in the Sandbox without requesting unauthorized global disk access.

Simulation mode (dry run)

Simulate cleaning to calculate the exact disk space to be freed and review details before any permanent deletions.

Xcode open detection

The app checks if Xcode is currently running and warns you to close it to avoid compile conflicts or data corruption.

100% local and private

No account required, no third-party tracking, zero cookies. All scanning and clean-up actions execute completely offline.
