What comes back on its own
Caches, Xcode and npm build products, installers for apps you already have, AI models you can download again.
For macOS 26 Tahoe
Clutterfall reads your Mac, says in plain words what each big thing is and what is safe to remove, and moves it to the Trash — so anything can come back.
Free for good if you start before 1 May 2027No accountNo network code
Caches, build products and used installers — nothing you made.
The Sweep
The quick look is ready in seconds, so you can reclaim at once. The full scan carries on behind it, and the AI review starts only if you allowed it.

The Space Map, large files you haven’t opened in a year, exact duplicates compared byte for byte.
3AI review if you allow it
Your own Claude Code or Codex suggests what could go. It sees names and sizes, never a file’s contents.
Space Map
Every ring is a folder, sized the way Finder sizes it. Zoom into anything, group by the app that owns it, or see what grew this week.
AI review
Connect the Claude Code or Codex you already use. It reads an inventory of a big folder and names what looks made again. Clutterfall then checks every path itself.

Safety
The rules are in the code, and tests and build checks hold them there. A move that can’t be undone has its own button and its own warning.
URLSession, a socket or a web view./System, /Library, Documents, Desktop, Downloads, Photos, Mail, Keychains, .ssh — and anything a symlink points at.
Clutterfall finds what an app leaves behind by its bundle ID, never by a guess at its name, and moves app and leftovers together.

Activity lists every move with what went and where. It also notices caches that came back, and folders that grew on their own.

AFTER
One purchase, no subscription. It also unlocks this website version: open the App Store copy once, then put this one in its place.
Looking around — every scan, size and explanation — stays free.
Put it back. Everything goes to the Trash, and Activity returns it to exactly where it was — one item, one group or everything. Only emptying the Trash frees the space for good, and Clutterfall says so before you do.
No. Clutterfall has no network code at all, and a build check keeps it that way. If you connect Claude Code or Codex for the AI review, that tool sends names and sizes of the folders you allow, through your own account, and you can read every word in “What was sent”.
It runs in Apple’s sandbox, so it sees less: it can’t list local Time Machine snapshots, its catalog is smaller, and the AI review isn’t there. Buying it unlocks this website version too, which can do all of that.
Full Disk Access, which you grant in System Settings — Clutterfall walks you through it. Without it, Clutterfall still works on your home folder.
Any Mac with macOS 26 Tahoe or later.
