Fedipub

Ruby Library for adding ActivityPub Federation

Fedipub is an open source library that implements the ActivityPub standard as a pluggable engine for the the Ruby on Rails web framework. By providing a common implementation of the standard using Rails idioms and design, it makes it easy for developers to add federation to their existing Rails applications, or create completely new ones. While Fedipub is already running in real-life applications to an extent, this project will improve documentation and onboarding, implement the rest of the core ActivityPub standard and add common Fediverse enhancements.
