Disk Census vs OmniDiskSweeper

Largest first, plus what each item is and whether it comes back.

Only in Disk Census

What Disk Census does that OmniDiskSweeper doesn’t, going by OmniDiskSweeper’s own pages.

  • It says what each item is

    Every item is tagged Safe, Review or Keep, with what regenerates it.

  • Developer and AI agent cleanup

    Xcode, Homebrew, npm, Cargo, Go, Python and more, plus the old versions and caches AI coding agents leave behind, with their history kept.

  • Duplicates and apps in the same scan

    Identical files found by content, and apps removed with their data, from the same scan as everything else.

  • A command line for scripts and agents

    census ships inside the app with JSON on every command, so scripts and AI agents see what the app sees.
