simple, minimalistic ActivityPub instance

 Runs as a daemon (proxied by a TLS-enabled real httpd server) and
 provides the basic services for a Fediverse / ActivityPub instance
 (sharing messages and stuff from/to other systems like Mastodon,
 Pleroma, Friendica, etc.).
 .
 It is lightweight, with minimal dependencies, and no database is
 needed. It has extensive support of ActivityPub operations, and is
 tested for interoperability with similar software. It also features a
 simple but effective web interface with an easily-accessed Mute
 button.
