Motrix Next

Motrix Next is a modern, open-source cross-platform download manager built as the official next-generation successor to the original Motrix project. It has been completely rewritten using Tauri 2, Vue 3, TypeScript, and Rust, while still relying on the powerful Aria2 download engine for high-speed multi-protocol transfers. The app supports HTTP, HTTPS, FTP, BitTorrent, and magnet links, offering advanced features like multi-connection acceleration, task scheduling, bandwidth control, and batch download management. With a significantly reduced install size (around 20MB), it focuses on being lightweight, fast, and resource-efficient compared to traditional Electron-based download tools.

Designed for Windows, macOS, and Linux, Motrix Next delivers a clean, modern UI inspired by Material Design 3 principles, with smooth animations and a minimal workflow. It improves usability through better download organization, system tray integration, and enhanced torrent handling including selective file downloads and tracker management.

Motrix Next features:

Multi-protocol downloads — HTTP, FTP, BitTorrent, Magnet, .torrent, and Metalink tasks
BitTorrent — Selective file download, DHT, peer exchange, encryption controls, metadata caching, GeoIP peer flags, and tracker probing
Browser extension integration — Embedded Extension API with independent authentication, download confirmation, smart auto-submit, filename hints, referer/cookie forwarding, and real-time controls (Chrome Web Store · Edge Add-ons)
Safe filename handling — Content-Disposition, RFC 2047, non-UTF-8, percent-encoded, and extensionless URL resolution with path traversal sanitization
Download organization — Favorite and recent folders, optional file-type categorization, stale-record cleanup, and completed history backed by SQLite
Concurrent downloads — Independent controls for active tasks, HTTP connections per server, segments per file, and BT peer limits
Speed control — Global and per-task upload/download limits with day-of-week and time-of-day scheduling
System integration — Tray operation, optional tray speed display, macOS Dock badge/progress, protocol handlers for magnet://, thunder://, and motrixnext://
Lightweight mode — Destroys the WebView on minimize-to-tray while Rust keeps the engine, task monitor, notifications, history, and extension routing alive
Notifications and power options — Native task start/complete/failure notifications, keep-awake during downloads, and optional shutdown after completion
Network controls — Scoped proxy support for downloads, app updates, and tracker updates, plus system proxy detection
Auto-update channels — Stable, Beta, and Latest Across Channels policies with separate download and install phases
Diagnostics — Structured logs, exportable diagnostic ZIPs, database integrity checks, automatic DB rebuild, and Linux GPU rendering fallback
Personalization — Light/dark/system theme, 10 color schemes, 26 languages, and first-launch system language detection

Motrix Next 3.8.10 changelog:

Motrix Next 3.8.10 promotes the 3.8.10 beta line to stable. This release adds HTTP Basic authentication support, improves local port conflict recovery, prevents system idle sleep during active downloads, and updates the README around the aria2-next engine integration.

New Features

HTTP Basic authentication — Adds credential management for downloads that require HTTP Basic authentication.
Automatic port conflict recovery — Detects local port conflicts and switches ports automatically when recovery is possible.
Power guard — Keeps the system awake while downloads are active without forcing the display to stay awake.

Improvements

Improved error reporting when port auto-switching cannot recover from a conflict.
Updated README feature and installation guidance.
Clarified that Motrix Next now uses the maintained aria2-next engine.
Improved README shield formatting and architecture table clarity.
Standardized locale key formatting in Vietnamese, Simplified Chinese, and Traditional Chinese preference files.
Renamed SignPath test workflow steps for clearer CI output.
Added SignPath workflow coverage for artifact configuration validation.

Bug Fixes

Fixed the SignPath certificate subject check by using Contains matching instead of -notlike.
Moved stat service shutdown logic into the correct engine service position.

Motrix Next 3.9.0 Beta 2 changelog:

Fixed repeated Extension API port auto-switching on Ubuntu during manual or settings-triggered engine restarts.
Prevented the engine restart path from treating Motrix Next's own Extension API listener as an external port conflict.
Kept Extension API fallback recovery active for real bind failures when the API itself starts or changes ports.
