> [!IMPORTANT]
> **Motrix Next is now Rayburst.** We recommend uninstalling the previous desktop app before installing Rayburst. Settings, tasks and history are not imported; keep your downloaded files. In-app updates may leave both apps installed or retain old shortcuts. Visit the [website](https://rayburst.pages.dev).

> [!NOTE]
> Rayburst uses [Aria2 Next](https://github.com/AnInsomniacy/aria2-next) as its download engine, 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.

## Design & Motion

Every transition and micro-interaction has been carefully tuned to follow [Material Design 3](https://m3.material.io/styles/motion/overview) motion guidelines:

- **Asymmetric timing** — enter animations are slightly longer than exits, giving new content time to land while dismissed content leaves quickly
- **Emphasized easing curves** — decelerate on enter (`cubic-bezier(0.2, 0, 0, 1)`), accelerate on exit (`cubic-bezier(0.3, 0, 0.8, 0.15)`), replacing generic `ease` curves throughout the codebase
- **Spring-based modals** — dialogs use physically-modeled spring animations for a natural, responsive feel
- **Consistent motion tokens** — all durations and curves are defined as CSS custom properties, ensuring a unified rhythm across 12+ components

## 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. See [media downloads](docs/MEDIA.md).
- **BitTorrent** — Selective file download, DHT, peer exchange, encryption controls, metadata
