Motrix-Mac
A native SwiftUI rewrite of the original Motrix download manager. Multi-protocol, lightweight, no Electron. Bundled aria2 engine with automatic health monitoring.
What Motrix-Mac does.
Each feature exists because it solves a real problem.
Multi-protocol downloads with torrent file selection.
Add tasks via URL or .torrent file. Built-in Bencode parser lets you pick individual files from a torrent before downloading.
- HTTP, HTTPS, FTP, BitTorrent, Magnet, Thunder
- Drag and drop .torrent files or URLs onto the window
- Thunder link decoding handled natively
Fine-grained control, zero hassle.
Configure connections, speed limits, BT seeding, UPnP, and startup behavior. All settings apply instantly via aria2 JSON-RPC.
- Engine watchdog — auto-restart on failure every 2s
- Adaptive polling — 500ms active, 6s idle
- UPnP port mapping via pure Swift SSDP/SOAP
- Auto tracker sync on launch
Under the surface.
