About Matrix Matrix is an open protocol for decentralised, secure communications.
Matrix Manifesto We believe:
People should have full control over their own communication. People should not be locked into centralised communication silos, but instead be free to pick who they choose to host their communication without limiting who they can reach. The ability to converse securely and privately is a basic human right. Communication should be available to everyone as a free and open, unencumbered, standard and global network.
I tried their most popular and featureful client(element) but it looks like their video calling still relies on jitsi which has very subpar screensharing support. And it seems that it’s because jitsi is for video conferencing type stuff so when I put an issue up about it, they didnt care that e.g. it was not good above 5fps
Being able to show off a game or watch a movie with friends (without needing to mess with Virtual Audio Cables so there’s no weird echo from their voices) in as little as 2 mouse clicks is the single killer feature Discord has that will make it incredibly hard for me to replace
The free open public jitsi do get bogged down now and then. And based on where you are located, can be far away. I run my own jitsi instance, so do not have that problem.
Also element is working on a built in call function that do not use jitsi. But i have not tested it. https://element.io/blog/element-call-beta-3/
