Scalable IRCv3.2 compliant chat daemon
Charybdis is the IRCv3 reference implementation. It has good
documentation and ease of configuration.
Charybdis is used on various networks either as itself, or as the
basis of a customized IRC server implementation. One such
customization is ircd-seven which powers Freenode, the largest IRC
network in the world.
There is no official package available for openSUSE Leap 15.4
