Motrix-NEXT

v0.1.2, supporting spliting the task to multiple threads.

Had a hard time implementing this becausereqwest have no native method for multi-thread, I have to build the wheels on my own. So the idea is fetch the file size with the metadata first and split it, and then fire http requests. At the same time keeping a .chunk file so any paused task can be resumed

Added more test to increase the test coverage, this helps future development by ringing any unintended changes.

I made a rpc endpoint before, but it does not work with apps like aira2 explorer.
I have implemented a new WebSocket endpoint, so it work exactly same as before (when it was using aira2)

One problem I encountered is that the file cannot be automatically deleted when I delete task, if the task is added via json-rpc, and I found out that in update_progress, it pass the path as a raw URL, resolving the path with task.dir fix the issue

Fixed linter and type errors, nothing special

Support M3U8 with ffmpeg .ts -> mp4

Implemented SFTP, also fixed torrent seed ratio not applying

Completed RSS implementation, filter/order setting in task list also works now

Add a landing site for motrix-next, https://motrix-next.vercel.app

Simplify some css, and re-do the ed2k engine (thats older than me). Added category path so downloaded items can automatically go to their preferred folders. Also it can save credentials automatically now. I have also refactored some logic and moved some from vue to rust to prevent lag

Finished off torrent and optimize its performance, now deleting task/adding task would not block the UI

Moved torrent to librqbit… there are still some bugs like task list spliting, will fix later today

Added ed2k support

migrated aria2 to reqwest, which is pure rust, that could optimize memory performance, also aria2 has not been updated for a few years already, so I think its better to move away from that

• Moved most of the logic from vue to rust backend
• Patched multiple download/performance issues
• Upgrade aria2c to support up to 128 splits

Today, we:

• Added option to allow custom CLI flags in aria2c
• Fix window not draggable
• Fixed start motrix via double-clicking a torrent file will launch new instance instead of using the existing one

Added graph to task details

Fixed:

1. Large torrent freeze - we got new “file explorer” view for torrent
2. Fix “do not seed” setting in preference does not work
3. Add UI overlay for loading
   New features:
4. Added page settings to tasks page, showing up to 50 tasks per page
5. Auto-retry for failed tasks with exponential backoff settings
6. Auto detect low speed tasks and pause/resume them

Fixed the tray localization not following language settings, and remove uPnP settings from preference (not supported in aria2c)

I am aware that the app freezes when a large torrent (~10mb) is provided, thats what I will be working on tonight

Today was mostly reliability and behavior fixes, with a few UI upgrades

• Added anti-idle handling while downloads are active. The app now uses tauri-plugin-nosleep, with Rust fallback
• Hide Tray speedometer now works
• open-at-login is now synced with OS autostart state.
• Auto-resume on launch works now
• Drag-and-drop for torrents in Tauri windows works now, added read_binary_file so dropped file paths can be loaded
• Reworked torrent parsing in SelectTorrent.vue with an in-renderer bencode parser
• Added duplicate-name checker before creating tasks
• Task deletion procedure for torrent is now: pause first, await cleanup, surface failures, and clean generated metadata torrent sidecars by info hash
• Preference handling is stricter, made sure every settings apply
• Startup-only aria2 options are handled correctly now, runtime options go through changeGlobalOption, startup-only ones trigger engine restart
• Reduced defaults and limits from 64 to 16 (Original aria2c)
• Added file:// to detected resource tags
• Updated Firefox UA preset and adjusted Chrome UA
• Added per-split progress bars in task details
• Number input and checkbox bindings were cleaned up for newer component APIs + better click feedback styling

Motrix is the downloader everyone loved - however it is left unmaintained for three years already.
What Im doing is basically a huge modernization and some new features, left in the original project’s FRs.
What has been done:

• Moved the app to Vue 3 + TypeScript + Vite
• Swapped Vuex to Pinia
• replaced Element UI with shadcn-vue components
• Moved from Sass to Tailwind
• Migrated desktop runtime from Electron to Tauri (Better memory performance/smaller bundle size)
  We fixed follow-up build issues and refreshed packaging/assets so the new stack actually ships cleanly.
• Added real features on top:
  • task queue move up / move down
  • configurable RPC host
  • smarter RPC reconnect when host/port/secret changes
  • better progress display and some UI polish (speedometer, drag/select, timing tweaks)
