Reclaim - Mac Storage Cleaner for Developers
Overview
Reclaim is a free, open-source storage cleaner for macOS built for developers. It finds the build caches, installed dependencies, simulators, and Docker leftovers that fill up a Mac, explains what each item is and whether it is safe to delete, and frees the space in one click.
It is a native SwiftUI app for macOS 14+ on Apple silicon and Intel. Scans walk the whole disk in parallel and measure the space files actually use, counting hard links once and leaving other drives alone. It has no account, no analytics, and no network access, so the file list never leaves the Mac.
Key features
- Detection rules for build output, dependencies, and package-manager caches, written from real developer Macs
- Three safety levels (Safe, Rebuild, Personal), with only Safe items ticked by default
- One-click cleanup, with the option to send items to the Trash and a summary of anything that couldn't be removed
- Byte-for-byte duplicate finder that doesn't double-count shared-storage APFS copies
- Docker and OrbStack cleanup through Docker's own commands, never by touching the disk image
- Hard limits that protect system folders, the home folder, and folders like Documents, including through symlinks or .. paths
- Disk Map, menu bar item, scheduled scans, auto-clean, and low-space alerts
- MIT licensed
