Kudu

Kudu is an open-source system utility that cleans, optimizes, and secures computers across multiple platforms. It includes 15+ tools for removing temporary files and caches, monitoring performance in real-time, auditing security settings, scanning for malware, updating software, and scheduling maintenance tasks. The suite replaces multiple paid utilities in a single ad-free application that runs entirely locally.

Designed for users seeking to reclaim disk space and improve system performance without bloatware or upsells, Kudu offers features like cleanup receipts showing what was removed, storage history tracking folder growth over time, a recovery center for restoring settings, and a game mode optimizer for Windows. The project is MIT licensed and available in 30 languages.
