A full-featured download manager — rebuilt from the ground up.
Free and open source
~10 MB lightweight bundle
Motrix by agalwood was one of the best open-source download managers available — clean UI, aria2-powered, cross-platform. It inspired thousands of users and developers alike.
The original project has been largely inactive since 2023. The Electron + Vue 2 + Vuex + Element UI stack accumulated technical debt, making it increasingly difficult to maintain, extend, or package for modern platforms.
We owe a great deal to the original Motrix and its community.
The aria2 error code system and JSON-RPC communication layer for the download engine.
25+ community-contributed locale files covering Chinese, Japanese, Korean, Arabic, French, German, and more.
Tracker list management, cURL command parsing, and other protocol-level helpers.
Every layer of the application has been redesigned and reimplemented from scratch.
| Layer | Motrix (Legacy) | Motrix Next |
|---|---|---|
| Runtime | Electron | Tauri 2 (Rust) |
| Frontend | Vue 2 + Vuex | Vue 3 Composition API + Pinia |
| UI Framework | Element UI | Naive UI |
| Language | JavaScript | TypeScript + Rust |
| Styling | SCSS + Element theme | Vanilla CSS + custom properties |
| Engine Management | Node.js child_process | Tauri sidecar |
| Build System | electron-builder | Vite + Cargo |
| Bundle Size | ~80 MB | ~10 MB |
| Auto-Update | electron-updater | Tauri updater plugin |
The UI layout stays true to Motrix's original design — the sidebar navigation, task list, and preference panels follow the familiar structure.
Everything underneath changed. Every transition and micro-interaction follows Material Design 3 motion guidelines.
Enter animations are slightly longer than exits. New content takes time to land; dismissed content leaves quickly.
Decelerate on enter, accelerate on exit. No generic ease curves.
cubic-bezier(0.2, 0, 0, 1)cubic-bezier(0.3, 0, 0.8, 0.15)Dialogs use physically-modeled spring animations for a natural, responsive feel.
All durations and curves are CSS custom properties, ensuring a unified rhythm across 12+ components.
HTTP, FTP, BitTorrent, Magnet links.
Selective file download, DHT, peer exchange, encryption.
Auto-sync from community tracker lists.
Up to 10 tasks with configurable thread count.
Global and per-task upload/download limits.
Real-time speed display in the menu bar (macOS).
Native dark theme with system preference detection.
Auto-detects system language on first launch.
Pause, resume, delete with file cleanup, batch operations.
Register as default handler for magnet and thunder links.
System notifications on task completion.
Tauri-powered, minimal resource footprint.
