Headroom presents a free, open-source Mac disk analyzer and cleaner, with a treemap, duplicate finder, and menu-bar disk monitor.

Landing page captured for the 2026-10-06 issue.

For: Mac users managing crowded disks, especially developers
Worth noticing: Duplicate matching uses four passes—size, header, samples, then full hash—to avoid reading large files unnecessarily.

Field notes

The homepage says scans use macOS’s getattrlistbulk directory-reading interface and are distributed across CPU cores. Its examples distinguish regenerable caches from settings or user data that should be checked first, and identify keychains, Mail, Photos libraries, and system files as items the app will not treat as safe to remove.
