# Disk Census vs OmniDiskSweeper

OmniDiskSweeper lists your files from largest to smallest and lets you trash them. Disk Census also tells you what each item is, whether it rebuilds itself, and what’s safe to clear.

## In short

- OmniDiskSweeper lists files largest first and lets you trash or open them. Disk Census also tags each item Safe, Review or Keep, with what regenerates it.
- Disk Census knows developer caches, AI coding agents’ leftovers and duplicates. OmniDiskSweeper shows sizes and leaves the judgement to you.
- OmniDiskSweeper sends what you remove to the Trash. Disk Census deletes permanently, after you approve the exact items.
- OmniDiskSweeper is a free download from Omni. Disk Census is a one-time purchase with every future version.

## Only in Disk Census

- **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.

## Questions

### Is Disk Census a good OmniDiskSweeper alternative?

If you want to know what you’re deleting, yes: Disk Census tags each item Safe, Review or Keep and knows developer caches and AI agents’ leftovers. If you just want a free list of what’s biggest, OmniDiskSweeper does that.

### Does Disk Census use the Trash like OmniDiskSweeper?

No. Disk Census deletes permanently, after you approve the exact items, and every confirmation says so. It checks each item again against a fresh scan first, and writes an audit on the Mac.

### Can Disk Census show the biggest files first?

Yes. Large Files lists the biggest files and folders, filtered by size and by when they were last opened or modified.
