Open-source Disk Cleaner & Storage Analyzer
"MangoDisk is a free, open-source disk cleaner and storage analyzer for Windows and macOS. See what is filling your drive with a visual treemap, then clear unwanted caches, duplicate files and app leftovers without digging through folders by hand. File paths and sizes are shown before deletion, so you decide what goes.
It also brings startup management, system maintenance and privacy cleanup into one desktop app. The latest release adds cleanup of browser, app and system activity traces, with a choice of time range. Scanning and cleanup run locally, with no account or login required.
The desktop interface is built with Vue 3 and TypeScript. Tauri 2 connects it to a Rust core that handles scanning, filesystem access, safety checks and cleanup. Vue powers the scan results, file review screens and interactive disk-space analysis. The source is available under GPL-3.0."
