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. Internally, agents create and consume events that propagate along a directed graph, which means one agent's output becomes another agent's input and a chain of small steps can be composed into a larger workflow. The project lives in the Ruby ecosystem and is distributed as an official Docker image or installed locally from a forked repository.
