Features
Orbit scans a disk or folder, then lets you explore it, collect what to remove, and move it to the Trash.
Cleanup suggestions
The Suggestions tab finds caches, toolchains, installers, node_modules and big files. When a tool owns the data, Orbit shows that tool's cleanup command.

Sizes on APFS
APFS clones, like copied repos and git worktrees, share blocks. Orbit counts each file's private size and shows the shared part separately, so a size is what deleting the item would free.

Native scanner
orbit-scan is a multithreaded walker built on macOS's getattrlistbulk(2), written in C.
Runs locally
Everything runs on your Mac. Its API only answers on 127.0.0.1 with a per-launch token, and it refuses to trash system folders, top-level home folders or the scan root.
Finder actions and colors
Right-click for Reveal in Finder, Quick Look and Copy Path. Switch between Spectrum and Mono colors.
Installation
Orbit isn't notarized by Apple yet, so macOS blocks the first launch until you allow it.
Copy to Applications
Open Orbit.dmg and drag Orbit into your Applications folder.
Allow it to open
macOS blocks the first launch. Go to System Settings › Privacy & Security and click Open Anyway.
Grant Full Disk Access
For a complete picture, add Orbit under Privacy & Security › Full Disk Access.
Orbit uses the system's Python 3. If the Xcode Command Line Tools aren't installed, macOS offers to install them the first time Orbit runs.
