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 (on Windows and OSX).
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.

As you can see from the Desktop app screenshot, it's fast. Anecdotally from a few reports, it's 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
Just a regular Rust binary build process.
cargo build --release
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
PRs are very welcome.
- Only supports BitTorrent V1 over TCP
- As this was created for personal needs, and for educational purposes, documentation, commit message quality etc. leave a lot to be desired.
By default it listens on http://127.0.0.1:3030.

First of all, I love Rust. The project was created purely for the fun of the process of writing code in Rust.
I was not satisfied with my regular bittorrent client, and was wondering how much work would it be to create a new one from scratch, and it got where it is, starting from bencode protocol implemenation, then peer protocol, etc, etc.
