CCleaner charges $29.95 a year. Avast Cleanup charges $39.99 a year.
Both were caught doing shady things to the users paying them.
Someone built the open-source version that beats both for $0.
It’s called Kudu.
It replaces a dozen paid cleaning apps with one free suite. Clear out gigabytes of junk files. Scan for malware with multiple engines. Harden 30+ privacy settings that Windows leaves wide open by default. Update all your installed apps in one click so you never miss a security patch.
It even has a treemap that shows you where every gigabyte on your drive actually went, so you stop guessing what to delete.
The thing paid cleaners will never do: it’s fully open source. You can audit every scan and verify every delete yourself. No hidden data collection. No ads bundled in.
Works on Windows, macOS, and Linux. In 30 languages.
