Diskzy vs CleanMyMac: an honest comparison
CleanMyMac from MacPaw is an all-in-one Mac care suite. Beyond junk cleanup it includes malware protection, performance tools for background apps and login items, a duplicate finder, an app uninstaller and updater, cloud storage cleanup and a visual view of the disk. It has a 7-day free trial and a 30-day money-back guarantee, runs on macOS 11 or later, and is also available through the Mac App Store and Setapp.
Diskzy does less on purpose. It is a small app for three jobs: seeing what is on the disk, clearing what is safe to clear, and uninstalling apps with their leftovers. It has no malware scanner, duplicate finder or performance tools. It is paid once rather than by subscription, breaks macOS's System Data into named parts, and sends everything it removes to the Trash.
