Disk Census

Disk Census is a native Mac app that shows what is filling your disk and what is safe to remove. It is for developers, people who use AI coding agents, and anyone whose Mac keeps saying the disk is almost full without saying why.

The scan is read-only. Each item is marked Safe, Review or Keep, so you know what you are looking at before anything goes. Disk Census knows developer storage: Xcode data, build output, and caches from Homebrew, npm, Cargo and Python, and it tells you which ones rebuild themselves. It also finds the data that AI agents like Claude Code, Codex and Cursor leave behind.

It also covers large files, duplicates, apps with their leftovers (full uninstall), maintenance tasks under Optimize, emptying the Trash, a widget and a low-space monitor.

Nothing is deleted until you approve it, and deletion is permanent rather than a move to the Trash. The built-in census command line lets scripts and AI agents scan and clean with the same limits.

Files and scan results stay on your Mac. One-time purchase, no subscription, up to 3 Macs. Requires macOS 12 or later on Apple silicon or Intel.
