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. ## What It Does
