DiskDuo vs Wise Disk Cleaner
Wise Disk Cleaner is a well-liked free cleaner on Windows. It is a Windows program: there is no Mac version to compare against feature by feature. If you have come here because you wanted it on a Mac, this page is about what the equivalent looks like on macOS.
The short answer
On Windows, Wise Disk Cleaner is a sensible free choice. On a Mac you need something else, and the thing to insist on is that it shows you every file before it removes anything, and that it moves them to the Trash.
Side by side
| DiskDuo | Wise Disk Cleaner | |
|---|---|---|
| Platform | macOS 14 or later, Apple silicon and Intel | Windows |
| Price | One payment | Free, with a paid Pro tier on Windows |
| Disk map | Nine views of one scan | A disk analyser on Windows |
| Removal | Trash, reversible | Windows Recycle Bin or permanent, by task |
| Analytics | None | See their Windows privacy policy |
What a Mac cleaner actually has to handle
Sandboxed containers under ~/Library/Containers, group containers keyed to a developer’s team, caches that rebuild themselves, iOS simulator runtimes that run to tens of gigabytes, Xcode derived data, and APFS clones that make a copy free. A cleaner that does not know these will either miss most of your space or offer to remove something it should not.
The rule to insist on
Whatever you use, insist on seeing the list before anything is removed, and on the Trash rather than immediate deletion. DiskDuo is built that way on purpose: staging is not deleting, every path is re-checked in the engine at the moment you confirm, and macOS’s own folders cannot be staged at all.
Where Wise Disk Cleaner is the better buy
On Windows, Wise Disk Cleaner is free, small and does what it says. Nothing here is a criticism of it; it simply does not run on a Mac.

The others.
DiskDuo vs CCleaner
CCleaner made its name on Windows. DiskDuo is written for macOS alone: APFS-aware sizes, a real disk map, and a cleanup step that shows every file first.
DiskDuo vs DaisyDisk
DaisyDisk is the prettiest disk map on the Mac. DiskDuo gives you nine views of the same scan, plus duplicates, an app uninstaller, and a macOS security check — for one payment.
