For XMPP, the Movim client is currently the best option as a discord alternative.
It has group voice and video calls, screensharing w/audio (need a chromium browser to share the audio for now), and just added discord-like channels with rooms (though it’s not as smooth as Discord). The Dev plans to implement drop-in voice rooms at some point as well.


You could use the GPU to help host a peertube instance.
