Caches, logs, support files, saved states — the clutter your apps forget to clean up. Nix finds every byte, shows you exactly what it is, and removes only what you choose.

The hidden footprint
When you install an app, macOS reports the bundle size — the icon you dragged to Applications. But the app keeps writing: derived data, device support, render caches, logs, saved states. None of it shows up next to the app, and almost none of it is removed when you delete it.
Nix measures the whole footprint, app by app, so the number you see is the number that’s actually on your disk.
What Nix does
No one-click “optimize.” No scare tactics. Nix shows you what’s there, in plain terms, and lets you decide.
Open Nix and it quietly scans your whole library in seconds — no buttons to hunt for. Results fill in live as each app resolves.
Scan a dense list when you want speed, or switch to a calm card grid that sells each app’s footprint at a glance. One tap between them.
Open any app to see its files grouped by kind — Application Support, Caches, Logs, Saved State — each with a real path and size. Check exactly what you want gone. Nothing is removed without your say-so, and your files never leave your Mac.
Apps that are already tidy say so. Buttons disable instead of nagging. No notifications, no upsells, no “your Mac is at risk.” Just the truth about your disk.
Every scan runs locally. No account needed. Nix never sees your files content – neither do we. #
The Examine view
Cleaners that hide what they delete are how people lose work. Nix does the opposite — it lays every file on the table first.
