I have tried XMPP, Matrix and now I've settled on Mumble.
Me and my fellows mostly just need a voice room or a couple to sit in, and Mumble does that best out of these three, in my opinion.
I recommend giving Mumble a try as it is super easy to set up and use. Users don't need to even create accounts to join servers.
I second this. My gaming group probably won't leave discord for the foreseeable future but Mumble is probably where we'd go if we did. IMO all these Discord alternatives are trying to do everything Discord does, when even Discord can't pull it off sustainably at their scale.
I don't want federation. I don't want it to scale to infinite concurrent users. What I want is something simple I can plonk on a crusty old laptop running Proxmox or a Raspberry pi for a few friends.
Even on a crusty old laptop you can easily serve hundreds of users with Mumble
IDK, said laptop is from 2010.
Limiting factor will probably be network - if you hook it up with cable, it should be fine
Mumble is nice, but it hasn't changed much since the time people explicitly moved away from it to Discord, so why would they go back it it now?
Mumble isn't requiring you to submit your ID.
Probably nothing has really changed. And I am not claiming it to be a Discord killer, as it really only does the voice rooms well.
But I am recommending it if you and your friends just need a voice room or two (as me and my friends do).
Mumble is fantastic.
I designed and implemented a very complex voice system for an old guild. Like 100 people, 8 groups of 15, group leader's private chat, priority speech all that. It worked so well, and never failed.
This was many many years ago, to be fair.
I wish it's positional audio was more supported.
Mumble was the primary choice for EVE Online groups.
You can literally have thousands of users on the same server.
In EVE, during big fleet fights (like 1000+ people on the same "team"), you can have a hierarchy of fleet commanders/wing commanders/squad leaders where voice travels down the chain of command, but not up.
Also the certificate based security with ACLs is just unmatched. You can set it up exactly how you want.
Also easy to integrate with, which is important for something like EVE.
