@swetland @debacle I'm not sure. I've always liked the idea of XMPP but have not followed it closely. For me, I don't think docker is as much a deal breaker, but I do wonder if there's a way to have a better CLI around docker that takes off some of the rough edges. Just having a static binary still means you would need to muck with init/systemd files so I guess a lot depends on what system admin warts you're most used to 🙃
I'm not aware of a single static #Jabber/ #XMPP server. Somebody needs to write such a thing!
Both #ejabberd by @ejabberd and #prosody by @prosodyim are pretty easy to install and maintain. Esp. if using distro packages.
If docker is an option, there is #snikket by @snikket_im, a pre-configured prosody.
Maybe check #openfire by @news or #tigase by @tigase? Never tried them.
