Overview
One scan, one total, and a quick look at system health.
- Smart Scan across Developer, Cleanup, Applications and Performance
- Cancel any time
- Nothing is deleted until you press Clean
Your Mac is full. Let’s see why.
OpenBroom finds what is eating your disk (node_modules, Xcode, Docker, caches), explains each thing in plain words, and removes only what you pick.

Press Scan. Click anything.
This runs in your browser on a made-up Mac, so nothing real is touched. Watch the disk bar fill, tick items, read why each got its label, then clean.

Ready when you are
OpenBroom only looks. Nothing is removed until you press Clean.
Made for developers’ Macs.
Xcode, Docker and node_modules leave a lot behind. OpenBroom knows where each tool keeps it, and how it comes back.
What do you build with?
Pick a stack to see what OpenBroom looks for, and the command that brings it back.

Per project, with last-worked date and git status. Projects with uncommitted changes are skipped.
Every item gets a label, not a guess.
Each one says what it is, whether it is safe to remove, and whether it comes back. Sort six everyday things and see if you agree.
Xcode DerivedData
~/Library/Developer/Xcode/DerivedData
Build products from every project you have opened in Xcode.
Where does OpenBroom put it?
Pick the label you think it gets.
OpenBroom never cleans behind your back.
Scanning only scans
Nothing is removed until you press Clean. Dry-run mode and an exportable report show exactly what would happen first.
Trash first, with undo
Files move to the Trash so you can put them back. If something cannot be trashed, the tool’s own command is named before it runs.
Zero network calls
No account and no analytics. Symlinks are never followed, and system, Photos, iCloud Drive, Mail and Time Machine paths are refused in code.
Scan. Understand. Clean.
It plays through on its own. Click a step to jump to it.
The whole app, one card at a time.
Native, quick and quiet. Keep scrolling and each screen slides over the last.

Developer
Junk with context: which project, how old, and how it comes back.
- node_modules, build output and virtualenvs per project
- Package caches, Xcode and Docker through their own tools
- Projects with uncommitted changes are skipped
03 / 07
Cleanup
App caches, logs, old downloads, device backups and the Trash.
- One item per app, each explained
- Old iOS updates and device backups, clearly marked
- Safe items are preselected, the rest are your call
04 / 07
Files
Large and old files that are yours to decide on.
- Large and old files, filtered by size and last opened
- Exact duplicates and similar photos
- Never preselected

Protection
A review of what starts on your Mac and what you downloaded.
- Startup items and recent downloads
- Optional ClamAV scan if you install it
- A review, not a real-time malware engine

Assistant
Ask what is safe to remove and get an answer from your own scan.
- Runs on your Mac with rules, not an online AI
- Try: what can I delete safely?
- Nothing leaves your Mac

Questions, answered plainly.
Can’t find yours? Open an issue and ask. It is an open-source project, so the answer ends up here.
Ask on GitHubIs it safe?
It is built to be careful: scans never delete, files go to the Trash, protected locations are refused in code, projects with uncommitted changes are skipped, and only Safe items are preselected. The code is open and has tests on fixture folders, so you can read exactly what it does.
What exactly does it remove?
Only what you select and confirm. Typical items are node_modules, build output, package caches, Xcode DerivedData and simulators, unused Docker data, old installers and app leftovers.
Why might it ask for Full Disk Access?
Only for Mail data, Safari data and the app-permission audit, which macOS protects. Everything else works without it, and you can say no.
Why is it not notarized?
There is no Apple Developer ID signing yet. The build is ad-hoc signed, so the first launch needs right-click, then Open. Notarization is on the list before any public release.
Will it speed up my Mac?
It frees disk space and shows login items and heavy processes. It does not promise a faster Mac, and it does not offer memory cleaning.
What does it cost?
Nothing. It is MIT licensed. If it saves you a day, a star on GitHub is a lovely thank you.
Who makes it?
