TLDR

rTorrent is a terminal-based BitTorrent client for servers and headless machines. Written in C++, it runs entirely in a text interface and pairs with the libtorrent library for protocol handling. No graphical interface needed, ideal for low-resource or remote systems.

Getting it running

Difficulty · moderate Time to first run · 1h+

Must match rTorrent and libtorrent versions exactly. Building from source requires autoconf, automake, libcurl, and ncurses dev libraries. Prebuilt packages available for major Linux distros.

Open source under the GNU GPL license. A small portion of cryptography code from Mozilla NSS carries a separate triple license. You can use and modify it freely but must share changes under the same license.

In plain English

rTorrent is a BitTorrent client designed to run in a terminal window rather than as a graphical desktop application. It was built for high performance and is controlled entirely through a text-based interface using the ncurses library, which draws panels and menus inside a standard command line shell. This makes it popular on servers, headless machines, and low-resource systems where a graphical interface is not available or practical. The project is written in C++ and is closely paired with a companion library called libtorrent, which handles the actual BitTorrent protocol work. The two projects must always be on the same version, so updating one requires updating the other at the same time. Beyond libtorrent, rTorrent also depends on libcurl for network transfers and ncurses for its terminal display. Building rTorrent from source requires a handful of standard Unix build tools, including autoconf and automake. After cloning the repository, you run a script to generate the build configuration, then follow the usual compile-and-install steps. Prebuilt releases are also available for those who do not want to compile it themselves. The project is open source under the GNU GPL license, with one small section of cryptography code borrowed from Mozilla's NSS library that carries its own triple license. The README is brief and directs users to an external wiki for the full usage guide and configuration documentation. Development is maintained by a solo creator who accepts donations through PayPal, Patreon, and several cryptocurrency addresses to keep the project going.

Copy-paste prompts

Prompt 1
I want to use rTorrent on a remote Linux server over SSH. Walk me through installing it, adding a torrent file, and checking download progress from the terminal.
Prompt 2
How do I write an rTorrent configuration file to set a download folder, limit upload speed, and auto-start torrents when they are added?
Prompt 3
rTorrent and libtorrent must be on the same version. How do I check which versions I have installed and update both at the same time on Ubuntu?
Prompt 4
I want to build rTorrent from source on a Debian-based system. Give me the exact commands from cloning the repo through running make install, including installing dependencies.
Prompt 5
How can I run rTorrent inside a screen or tmux session so downloads keep running after I disconnect from SSH?
