Why Kudu?

Most system cleaners are closed-source, ad-filled, and want your money. Some are barely disguised malware themselves.

Kudu is 100% free, open-source, and transparent. No ads, no upsells, no telemetry. You can read every line of code, audit every scan, and verify every delete. Built by developers who were tired of recommending CCleaner with a straight face.
