ForgeFed is an upcoming #federation #protocol for enabling #interoperability between version control services. It’s built as an extension to the #ActivityPub protocol, allowing users of any ForgeFed-compliant service to interact with the repositories hosted on other instances.

#ForgeFed is looking for #opensource contributors to their roadmap items, for which you'll receive funding (thanks to #nlnet )
