kepi

kepi is an ActivityPub daemon.

ActivityPub is a standard protocol for integrating social media across Internet sites.

For example, you might post an article. Someone else on another site might reply to it, and someone else might "like" it. Someone else again might "follow" you, in order to get notifications when you post anything else.

kepi runs in the background on your server, distributing your messages to other sites, and receiving their responses.
