Rayburst

Motrix by agalwood was one of the best open-source download managers available — clean UI, aria2-powered, cross-platform. It inspired thousands of users and developers alike.

However, the original project has been largely inactive since 2023. The Electron + Vue 2 + Vuex + Element UI stack accumulated technical debt, making it increasingly difficult to maintain, extend, or package for modern platforms.

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.

Design & Motion: The overall UI layout stays true to Motrix's original design — the sidebar navigation, task list, and preference panels all follow the familiar structure that made Motrix intuitive from day one.

What changed is everything underneath. Every transition and micro-interaction has been carefully tuned to follow Material Design 3 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
