Lita is a chat bot written in Ruby with persistent storage provided by Redis. It uses a plugin system to connect to different chat services and to provide new behavior. The plugin system uses the familiar tools of the Ruby ecosystem: RubyGems and Bundler.

Coming from Hubot

Lita draws much inspiration from GitHub's fantastic Hubot, but has a few key differences and strengths:

  • It's written in Ruby.
  • It exposes the full power of Redis rather than using it to serialize JSON.
  • It's easy to develop and test plugins for with the provided RSpec extras. Lita strongly encourages thorough testing of plugins.
  • It uses the Ruby ecosystem's standard tools (RubyGems and Bundler) for plugin installation and loading.
