Motrix — Full-Featured Cross-Platform Download Manager

Introduction

Motrix is an open-source download manager built on Electron and powered by aria2 under the hood. It provides a clean, modern interface for managing downloads across HTTP, FTP, BitTorrent, and Magnet protocols. Motrix runs on macOS, Windows, and Linux with a unified experience.

What Motrix Does

• Downloads files via HTTP, HTTPS, FTP, SFTP, BitTorrent, and Magnet links
• Supports multi-threaded downloading with up to 64 concurrent connections
• Provides a built-in torrent tracker list updater for better peer discovery
• Manages download queues with pause, resume, and scheduling
• Offers a browser extension for intercepting download links

Architecture Overview

Motrix wraps aria2, a lightweight multi-protocol download utility, inside an Electron desktop application. The Vue.js frontend communicates with the aria2 daemon via its JSON-RPC interface. This separation means the download engine runs independently of the UI, providing stability and the ability to control aria2 remotely if needed.
