It’s so much easier to set up and install than Matrix.

Unbelievably so. Mumble is… basically one setup command. Don’t even need a domain. And it needs absolutely no resources, can run on a Pi Zero.
Setting up my own Matrix server was honestly one of the most difficult things I’ve ever attempted in decades of non-professionally using computers and I’m still not sure I’d be able to properly take care of the installation if it breaks. Sooo many moving parts. All the federation-oriented projects that rely on adoption rates reaaaaally desperately need setup wizards before any other additional feature.

Have started it up as well because I fear like there might not be much time to enjoy its benefits for much longer :(

Looks pretty neat! Too bad there’s no standalone installation, only docker.
