Mole looks great — I hadn't seen it before. Go is a solid choice for this kind of tool.
The main differences from onClean:
- Mole is free/open-source (MIT), onClean is $5.99 one-time. If free matters most, Mole wins there.
- onClean's scanning engine is written in Zig with direct POSIX syscalls — different tradeoff (smaller
binary, no GC pauses during large scans).
- onClean has first-class support for developer-specific caches (Xcode DerivedData, nested node_modules,
Cargo, CocoaPods, Docker) which tend to be the biggest space hogs for devs.
- We also have a menu bar helper for scheduled cleaning and a recommendations system for stale
downloads/screenshots.
Honestly, the more tools in this space the better — CleanMyMac charging $40/yr for cache deletion has
gone on long enough. Thanks for sharing the link.
