This preview uses sample data. Mac scans are read-only; cleanup runs only after you confirm it.
Privacy
Scan read-only.
Clean by choice.
A scan only measures folders. Cleanup changes files only after you review and confirm it. Full Disk Access is optional; without it, protected folders are left out and the scan is marked partial, with the exact paths it couldn't read.
Made for how you work now
Where did 200 GB go?
Probably here.
Agent transcripts, local language models, build output, and Docker images each get their own color, so the big ones are obvious at a glance.

Cleanup
Review it. Then clean.
Right in Lunoom.
Pick safe suggestions, see the exact paths, and confirm. Generated folders move to Trash; package caches are pruned by their own tools after a location check. Review first items stay manual. You can still copy a script if you prefer.
# Lunoom cleanup — read before running
set -e
# Xcode DerivedData · 38.2 GB
rm -rf -- ~/Library/Developer/Xcode/DerivedData
# uv cache · 2.3 GB
uv cache prune
# Review first: open ~/.claudeFast from the keyboard.
Every view and action is a shortcut away. Or drop a Finder folder on the window.
