YOU'VE BEEN PAYING FOR WHAT YOU CAN HAVE FOR FREE FOR YEARS.

Kudu is an open source cleaning system and privacy protection tool for Windows, macOS and Linux.

deletes temporary files, browser cache, and residual data from applications that you have already deleted. It also includes malware scanning, disk analysis, auto-startup program management, secure file deletion, and privacy settings.

what is the difference from the usual commercial cleaning utilities?: Kudu is open source, ad-free, and without telemetry. He doesn't sell your data to "clean" your PC.

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.
