Lita is a chat bot written in Ruby with persistent storage provided by Redis. It can connect to any chat service (given that there is an adapter available for it) and can have new behavior added via handlers. The plugin system is managed with regular RubyGems and Bundler.
Lita provides an alternative to GitHub's Hubot for Ruby programmers.
