rayburst

Project Overview

Rayburst (formerly Motrix Next) is a full-featured open-source download manager powered by Aria2 Next as its download engine. Aria2 Next is a maintained aria2 fork that preserves the original interfaces while fixing long-standing issues, moving to CMake, adding native ED2K and HLS/DASH support, and updating modern dependencies.

Key Features

• Multi-protocol downloads: HTTP, HTTPS, SFTP, ED2K, BitTorrent, Magnet, and .torrent tasks
• HLS and DASH: Native track selection, subtitles, live recording, resumable media downloads, and MP4/MKV output
• 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 (with Rayburst Connect)
• 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 limits for active tasks, stream connections, and BitTorrent peers
• 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://, ed2k://, thunder://, and rayburst://
• 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, and Linux GPU rendering fallback
• Personalization: Light/dark/system theme, 10 color schemes, 27 languages, and first-launch system language detection
• Native desktop app: Tauri 2 with a Rust backend

Design & Motion

Every transition and micro-interaction follows Material Design 3 motion guidelines: asymmetric timing (enter animations slightly longer than exits), emphasized easing curves, spring-based modals, and consistent motion tokens.
