Fedipub

Fedipub is an engine that brings ActivityPub to Ruby on Rails applications.

Status

Fedipub is running in live production applications right now; it supports a basic subset of ActivityPub features, and is still changing internally, but it does work! You can:

• Discover actors via Webfinger
• Follow actors on other servers, and also be followed
• Send and receive activities about any type of object, including Notes
• Announce / boost activities

There’s a lot more to come though. We aim to:

• implement all the parts of the (RFC) labelled with MUST and MUST NOT
• implement some or all the parts of the RFC labelled with SHOULD and SHOULD NOT
• maybe implement the parts of the RFC labelled with MAY
• support many common FEPs

Currently Fedipub is bound to Rails; however, in the near future we will be making the Rails-specific parts optional, and explicitly supporting other frameworks, or just pure Ruby.

Supported Ruby / Rails versions

• Ruby: 3.3, 3.4 and 4.0
• Rails: 7.2, 8.0 and 8.1

Users

Fedipub is used by projects including:

• Manyfold
• Prismo

Extensions

As well as the core gem, other features are available in extensions:

• fedipub-moderation: Trust & Safety for Fedipub; reporting posts, blocking domains, and more to come.
