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.

About tapir
Tapir is a Scala library that lets developers describe an HTTP API once in a type safe, declarative form and then expose that description as a server, consume it as a client, and generate OpenAPI, AsyncAPI, and JSON Schema documentation from it, and it is aimed at Scala teams building HTTP services that want their API documentation to stay in step with their code.
