Limnoria is a multipurpose Python IRC bot, designed for flexibility and robustness, while being easy to install, set up, and maintain.

It aims to be an adequate replacement for most existing IRC bots. It includes a very flexible and powerful ACL system for controlling access to commands, an equality powerful configuration system to customize your bot, as well as more than 60 builtin plugins providing around 400 actual commands.

There are also dozens of third-party plugins written by dozens of independent developers, and it is very easy to write your own with only basic knowledge of Python.

It is the successor of Supybot since 2010 and provides many new features, but keeps full compatibility with existing configurations and plugins.



If this is your first install, there is an install guide. You will probably be pointed to it if you ask on IRC how to install Limnoria. TL;DR version:

sudo apt-get install python3 python3-pip python3-wheel
pip3 install --user limnoria
# You might need to add $HOME/.local/bin to your PATH

There is extensive documentation at and at Gribble wiki. We took the time to write it; you should take the time to read it.
