Reclaim the gigabytes
of cache you forgot
you had.
Your dev machine is hoarding tens of gigabytes of regenerable cache — npm, Puppeteer, Docker, Xcode, browsers. StorageJanitor finds it, shows where it went, and reclaims it — without ever touching your data.

See where it all went
A disk donut and a squarified treemap show exactly what's eating your storage — drill into any folder, live.
One-click safe cleanup
Per-app reclaimable cache vs. data you keep. Clean one app or all safe caches — with an exact preview before anything is deleted.
Fast, native scanning
A parallel getattrlistbulk scanner walks hundreds of thousands of files in seconds. No Electron — a real native app.
Self-updating
Signed auto-updates land in-app. A full audit log records every deletion, so you always know exactly what was freed.
Delete cache.
Never your data.
Every deletion passes four independent guards before anything is removed — and you see the exact paths and sizes first. "Safe" isn't a hope; it's structural.
