I've never set up my own IRC bouncer because I always thougth they were a pain in the a$$. But I have installed things like a Quassel Server and recently an instance of the Lounge. I have also paid for IRCCloud in the past. I've never really settled on anything.
Then comes sr.ht. No it's not an IRC server,it's a git repository like github, gitlab, etc... But they do provide an IRC bouncer provided by Soju and Gamja which you can access through them if you don't want to set anything up locally, you can just hit the web.
