What rsdirstat is
rsdirstat is a free, open-source disk usage analyzer for Linux, macOS, and Windows. It scans files and folders with multithreaded processing and platform-native APIs, then presents results in an interactive graphical treemap. The squarified layout supports zoom navigation, while colors can represent file type or modification time. Filters narrow the display by extension, size, or name. Clicking moves through the scanned tree, and a right-click can reveal an item in the file manager. A separate command-line binary lists the largest directories or files and accepts a configurable top-N count. The graphical interface runs as a local web app over WebSocket, with its frontend embedded in a self-contained binary. Prebuilt installers and Cargo installation instructions are available. Release 0.1.2 includes downloads for Apple Silicon and Intel macOS, x64 Windows, and ARM64 and x64 Linux, with checksums. The project uses the MIT license.
