What is it?

Kudu is a desktop utility that reclaims disk space, removes malware, and manages privacy on Windows, macOS, and Linux. It cleans system, browser, app, and game caches, manages registry entries and startup programs, and includes a disk analyzer, malware scanner, privacy controls, a software updater, and performance monitoring.

Cleaning rules are defined as plain JSON files, so new applications can be supported without writing code. Users can also add their own cache folders, including portable apps on other local drives, and preview and recover removed items from the Trash. Scheduled scans run on startup when installed via the installer, and a scriptable command-line interface is available.

The project is MIT licensed and runs locally, with the full source code available for review. It is distributed as an installer, portable build, DMG, AppImage, or DEB package.
