Why Motrix Next?
[!NOTE]
Motrix Next uses 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 support, and updating modern dependencies.
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.
What we rebuilt
Motrix Next is a ground-up rewrite — same download manager spirit, entirely new codebase.

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
Features
- Multi-protocol downloads — HTTP, HTTPS, SFTP, ED2K, BitTorrent, Magnet, and
.torrent 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 · Firefox 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://, ed2k://, 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
- Lightweight bundle — Tauri 2 + Rust backend with a ~20 MB application bundle
Installation
Download the latest release from GitHub Releases.
macOS
Homebrew (recommended):
brew tap AnInsomniacy/motrix-next
brew install --cask motrix-next
xattr -dr com.apple.quarantine /Applications/MotrixNext.app
Or download the .dmg installer from Releases:
| Architecture |
File |
| Apple Silicon |
MotrixNext_x.x.x_aarch64.dmg |
| Intel |
MotrixNext_x.x.x_x64.dmg |
The .app.tar.gz macOS artifacts are published for the Tauri updater and Homebrew cask automation.
[!TIP]
If macOS says the app is "damaged and can't be opened", see the FAQ below.
Windows
Scoop (recommended):
scoop bucket add extras
scoop install extras/motrix-next
Download the installer from Releases:
| Architecture |
File |
| x64 (most PCs) |
MotrixNext_x.x.x_x64-setup.exe |
| ARM64 |
MotrixNext_x.x.x_arm64-setup.exe |
Run the installer — it takes about 10 seconds, no reboot required.
Linux
Flatpak via FlatPark (x64 only):
flatpak remote-add --user --if-not-exists flatpark https://dl.flatpark.org/flatpark.flatpakrepo
flatpak install --user flatpark com.motrix.next
FlatPark maintains this community package independently with permission from the Motrix Next developer. It uses official release binaries and receives updates through flatpak update. See the FlatPark app page for details.
Or download directly from Releases:
Debian / Ubuntu:
sudo dpkg -i MotrixNext_x.x.x_amd64.deb
Fedora / RHEL:
sudo rpm -i MotrixNext-x.x.x-1.x86_64.rpm
Other distributions — use the .AppImage:
chmod +x MotrixNext_x.x.x_amd64.AppImage
./MotrixNext_x.x.x_amd64.AppImage
All formats are available for both x64 and ARM64.
FAQ
macOS says the app is "damaged and can't be opened"
This app is not code-signed. Open Terminal and run:
xattr -dr com.apple.quarantine /Applications/MotrixNext.app
This removes only Gatekeeper's quarantine attribute. Run it again after each Homebrew upgrade.
Why is there no portable version?
Motrix Next relies on Aria2 Next as its download engine and launches it through a bundled motrix-next-engine sidecar process at runtime. The sidecar binaries are built and released from the aria2-next repository for all 6 supported desktop targets. This architecture means:
- The Aria2 Next sidecar binary must exist alongside the main executable — it cannot be embedded into a single
.exe.
- Deep links (
magnet://, ed2k://, thunder://) and file associations (.torrent) require Windows registry entries that only an installer can configure.
- The auto-updater needs a known installation path to replace files in place.
These are fundamental constraints of the Tauri sidecar model and the Windows operating system, not limitations we can work around. Notable Tauri projects like Clash Verge Rev (80k+ stars) previously shipped portable builds but discontinued them due to the same set of issues.
We provide NSIS installers for Windows — lightweight (~20 MB), fast to install, and fully featured.
Code Signing
Motrix Next is not code-signed on macOS or Windows, so your browser or antivirus software may show a security warning when downloading or running the installer.
The app is fully open-source and every release binary is built automatically by GitHub Actions CI. For added peace of mind, you can always build from source.
Release .sig files are Tauri updater signatures, not GPG signatures. They can be verified with minisign using the following two-line public key format required by minisign:
untrusted comment: minisign public key: 76210453A979C645
RWRFxnmpUwQhdu1ykhDbEnVZguwQfLA60/oBA3rIlP0Z+L06b3u2NtJN
Save the key as motrix-next.pub, then replace MotrixNext_x.x.x_<file> with the release file you downloaded:
python3 -c 'import base64,sys; sys.stdout.write(base64.b64decode(sys.stdin.read()).decode())' \
< MotrixNext_x.x.x_<file>.sig \
> MotrixNext_x.x.x_<file>.minisig
minisign -V \
-m MotrixNext_x.x.x_<file> \
-x MotrixNext_x.x.x_<file>.minisig \
-p motrix-next.pub
Expected result:
Signature and comment signature verified
If the artifact was changed:
Signature verification failed

Built in the hours I should've been writing my thesis — I'm a PhD student surviving on instant noodles 🍜
This app is not code-signed on macOS or Windows — Apple charges $99/year, and a Windows Authenticode certificate costs $300–600/year. That's a lot of instant noodles.
Buy me a coffee ☕ — maybe one day I can afford those certificates, so antivirus software stops treating my app like a criminal 🥲
