I don't think one is setup currently, though based upon some of the IRC channels I'm in it sounds like one is getting actively worked on.

Hoping there's one soon, the only way I connect to IRC these days is through a Matrix bridge and I don't want to run one myself :)

Do you have your own server? How hard was it to set up?

I run my own homeserver. It wasn't too hard to set up but it's fairly resource-intensive. I have it on a big Ryzen and barely notice it but I think it would crush something like a Raspberry Pi (especially if you tried to run it off an SD card)
