A Tauri desktop disk usage analyzer built with Rust, React, and shadcn/ui.
Space Lenser gives you a desktop view into storage usage. It uses a Rust scanner backend through Tauri commands and a React frontend for drive selection, scan progress, hierarchical browsing, category breakdowns, and permission/error visibility.
- Filesystem explorer: Uses a Rust scanner backend with lazy directory discovery, cached listings, and streamed progress.
- Desktop UI: Tauri v2 shell with a React + shadcn/ui frontend.
- Scan progress: Tracks active scans and updates the explorer as results become available.
- Permission handling: Checks macOS Full Disk Access state and exposes the app permission request from the desktop UI.
- Access debugging: Shows unreadable paths and scan errors from the Rust backend.
- Smart navigation: Respects filesystem boundaries to avoid unexpected mounted-drive traversal.
- Usage distribution: Breaks usage down by file categories such as apps, media, code, and archives.
- Rust (latest stable version)
- Node.js and npm for the Tauri desktop frontend
- Tauri v2 system dependencies for your platform
