System Junk & browsers
User caches, logs, temp files, Mail Downloads, iOS backups, Safari / Chrome / Edge / Firefox / Arc — labeled before you touch them.
MacHygienist
Clear the junk. Keep the Mac.
Native Mac cleaner with the same safety rails you’d want on a family machine — and the reclaim depth developers actually need.
For everyone
Everyday clutter, labeled before you reclaim.
Scan free. Reclaim Safe System Junk and browser caches up to 2 GB lifetime on the free tier. Everything moves to Trash — never silent rm.
Unused files
Large docs, photos, video, and archives idle for ~180 days under Desktop, Documents, Downloads, and more. Multi-select → Trash with Review confirm.
Similar photos
On-device Vision clusters near-duplicates from Photos and loose folders. Keeps the best copy; Photos items go to Recently Deleted via PhotoKit.
Power users
See where space went — then take the biggest wins first.
Scan cache restores your last volume map on launch. Path sizes reuse an mtime cache so unchanged folders skip a full re-walk.
Biggest wins
Post-scan, rank the largest reclaim opportunities with plain-language what’s inside and a Safe / Review verdict — then Remove or deep-link in.
Space overview
Map Data folders as Reclaim / Archive / Protected. System, VM, and Preboot stay in “Protected by macOS” — no fake whole-disk math.
Installed apps
Applications, Homebrew Cellar/Caskroom, ~/.local. Prefer official removers (brew uninstall, cleanup) before Library leftovers.
Reports
Export JSON or Markdown. Disk stats: mapped vs unaccounted, safe-reclaimable totals, Trash size, session deleted.
Developers
Attribute junk to the apps and projects that own it.
A 100 GB .next cache ranks as Safe regenerable. node_modules stays Review — deleting it removes the toolchain until reinstall.
Toolchain caches
Xcode & simulators, Flutter, Android/Gradle, npm/pnpm/Yarn/Bun, Docker/Colima/Lima, CocoaPods, Cargo, Maven, Cursor/VS Code, Ollama, Hugging Face…
Project artifacts
Discovers ~/Developer, ~/Projects, ~/Code (and custom roots). Attaches build/, .next, node_modules, Pods, venv, checkpoints to the owning project.
Version managers
mise, asdf, nvm, fnm, pyenv, conda, rustup, SDKMAN, and more — sized installs, project pins, Remove via the manager’s uninstall CLI.
YAML rule packs
Add cache paths without shipping a new build. Safety: safeRegenerable, review, doNotTouch. Ship packs beside the app.
