biboumi

IRC gateway for XMPP

Project mention: IRC Is the Only Viable Chat Protocol | news.ycombinator.com | 2023-07-29

IRC is great! I access through the excellent biboumi gateway, which offers bouncer-like functionality and let me choose between various clients. There are open instances available for everyone to use, although I couldn't give a list of them since I self-host. I like that it's very lightweight, making it a reasonable permacomputing approach to group chats.
I wouldn't go as far as saying it's the only viable chat protocol, if you follow the link below you'll guess what I have in mind saying that. (it starts with an X and ends with two Ps)
