For those of you who don't know, the project was archived in 2024 but there was at least one modern fork of XChat in the form of HexChat: https://hexchat.github.io/
Honestly we're a little short on good IRC clients, so it's not that stupid.
I have resorted to rolling my own version of irccloud. It became embarrassing how much I spent over the years for such a simple service. Also learning then irc protocol in its bizarre entirety was pretty fun.
