SpaceInsight

SpaceInsight is a fast, cross-platform disk space analyzer. Its Rust scanning engine is paired with a Tauri desktop interface and an optional terminal UI.

• Parallel file-system scanning with jwalk and rayon
• Squarified treemap layout calculated by the shared Rust core
• Responsive Tauri 2 desktop interface with folder drill-down
• Live scan progress and top-level preview
• Native folder picker and file-manager reveal actions
• Separate mouse-enabled terminal UI

• Rust stable
• Node.js 20 or newer
• The Tauri system prerequisites for your platform

npm install
npm run tauri dev

The Vite frontend is also available at http://localhost:1420 while Tauri is running, but file-system commands require the desktop window.

npm run tauri build

Installers and application bundles are written beneath src-tauri/target/release/bundle/.

• Press / to edit the path and Enter to scan

The Tauri backend keeps the scanned FileTree in memory. The frontend requests layouts for the current directory, while build_render_tree and SquarifiedTreemap remain the single source of truth for tile geometry.
