Most Mac cleaners show you a big number and a Clean button. Crumb shows you what you're deleting. One read-only scan names every item, its size, and whether it comes back on its own: Xcode build data, npm and browser caches, old app versions. Things that rebuild themselves are ticked for you; your files never are. Not sure? Ask Safe? before you delete. Plus a full uninstaller, a duplicate finder and a Downloads tidier with undo. Runs on your Mac, no account.
