Revolt is a messaging social service (https://revolt.chat/) that is meant to be a replica of Discord within the FLOSS fashion, I set a test server for TMW here: https://rvlt.gg/N325NRWv
Feel free to try it out, right now it's unbridged to IRC or Discord.
First impressions: feels less cluttered than than using Matrix and I like the simple sleek design.
I'll add this to our official chat tools when I see more than 5 users online. It'll remain supported if people use it, so give it a try

I don't like it due to their service providers but, compared to discord, is a better alternative.
Personally, I prefer this one: https://tox.chat/
I had fun years ago with Mumble too.
I'm curious to see what community thinks about it...
Love the design, seems like a great alternative.
