It’s also made to be decentralized. Seems voice chat works already. Screenshare and video chat don’t seem to be released yet, but I was told that if you host your own instance, you can turn them on (vidchat and screenshare are probably still in beta/are experimental features I assume). UI layout is comparable to Discord.
Me and a friend are considering installing an instance on the server our peertube instance is installed on.
Decentralized ≠ Federated
But I don’t know if there is federation. It is decentralized because compared to Discord, everything isn’t on a central server but can be hosted on an independent instance. However bots that bridge servers between instances seem to already exist.
It would be a real game changer if it was federated!
