About huginn
Huginn is an open source system for building agents that perform automated tasks online, written in Ruby and released under the MIT license. Its agents read the web, watch for events, and take actions on the user's behalf.

The project lives in the Ruby ecosystem and is distributed as an official Docker image or installed locally from a forked repository.
