Kudu reclaims disk space, removes malware, and protects your privacy — without ads, bundled software, or upsells. Everything runs locally, and every line of code is open for you to audit.
It covers system, browser, app, and game cache cleaning; registry and startup management; a disk analyzer; a malware scanner; privacy controls; a software updater; performance monitoring; scheduled scans; and a scriptable CLI. See the website for the full feature list and the cleaner directory for every supported app.
Available in 30 languages.
