ActivityPub

Testing This category serves to broadly discuss test practices that help increase Fediverse interoperability. Server to Server This protocol is used to distribute activities between actors on different servers, tying them into the same social graph. Client to Server This protocol permits a client to act on behalf of a user. E.g., a mobile app to interact with a social stream of the user’s actor.
