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.
