Kroeg
Noun (plural kroegen, diminutive kroegje) - (informal) a pub.
A reference implementation for ActivityPub.
Info
This server can be set up to create a mostly-functional ActivityPub server, which is able to federate to other servers. It is mostly standalone, only requires a PostgreSQL server, and can be ran in load-balancing situations. See Kroeg.Server's README for more information.
