rqbit is a bittorrent client written in Rust. Has HTTP API and Web UI, and can be used as a library.
Also has a desktop app built with Tauri.
Assuming you are downloading to ~/Downloads.
rqbit server start ~/Downloads
Assuming you are downloading to ~/Downloads. If the server is already started, -o ~/Downloads can be omitted.
rqbit download -o ~/Downloads 'magnet:?....' [https?://url/to/.torrent] [/path/to/local/file.torrent]
Access with http://localhost:3030/web/. It looks similar to Desktop app, see screenshot below.
The desktop app is a thin wrapper on top of the Web UI frontend.
Download it in Releases for OSX and Windows. For Linux, build manually with
cargo tauri build
rqbit can stream torrent files and smartly block the stream until the pieces are available. The pieces getting streamed are prioritized. All of this allows you to seek and live stream videos for example.
You can also stream to e.g. VLC or other players with HTTP URLs. Supports seeking too (through various range headers). The streaming URLs look like http://IP:3030/torrents/<torrent_id>/stream/<file_id>
rqbit can advertise managed torrents to LAN, e.g. your TVs and stream torrents there (without transcoding). Seeking to arbitrary points in the videos is supported too.
Usage from CLI
rqbit --enable-upnp-server server start ...
Anecdotally from a few reports, rqbit is faster than other clients they've tried, at least with their default settings.
Memory usage for the server is usually within a few tens of megabytes, which makes it great for e.g. RaspberryPI.
CPU is spent mostly on SHA1 checksumming.
There are pre-built binaries in Releases. If someone wants to put rqbit into e.g. homebrew, PRs welcome :)
If you have rust toolchain installed, this should work:
cargo install rqbit
Docker images are published at ikatson/rqbit
Just a regular Rust binary build process.
cargo build --release
The "webui" feature requires npm installed.
Increase verbosity. Possible values: trace, debug, info, warn, error.
Will print the contents of the torrent file or the magnet link.
If you want to resume downloading a file that already exists, you'll need to add this option.
This will increase the default peer connect timeout. The default one is 2 seconds, and it's sometimes not enough.
Use a regex here to select files by their names.
- Sequential downloading (the default and only option)
- Resume downloading file(s) if they already exist on disk
- Selective downloading using a regular expression for filename
- DHT support. Allows magnet links to work, and makes more peers available.
- HTTP API
- Pausing / unpausing / deleting (with files or not) APIs
- Stateful server
- Web UI
- Streaming, with seeking
- UPNP port forwarding to your router
- UPNP Media Server
- Fastresume (no rehashing)
By default it listens on http://127.0.0.1:3030.
curl -s 'http://127.0.0.1:3030/'

First of all, I love Rust. This project began purely out of my enjoyment of writing code in Rust. I wasn’t satisfied with my regular BitTorrent client and wanted to see how much effort it would take to build one from scratch. Starting with the bencode protocol, then the peer protocol, it gradually evolved into what it is today.
What really drives me to keep improving rqbit is seeing genuine interest from users. For example, my dad found the CLI too difficult, so I built a desktop app just for him. Later, he got into Docker Compose and now runs rqbit on his NAS, showing how user feedback and needs can inspire new features. You can find other examples of new features born from user requests in the issues/PRs.
Hearing from people who use and appreciate rqbit keeps me motivated to continue adding new features and making it even better.
If you love rqbit, please consider donating through one of these methods. With enough support, I might be able to make this my full-time job one day — which would be amazing!
