Came across this on the r/selfhosted community. Still very much in the alpha stages, but it’s already got a Docker image you can try out for yourself, or try out the demo server.
Tried it earlier today, couldn’t get the voice/video chat to work right away on my self-hosted setup but the real-time chat was very snappy. Looks promising.
I see. I havent selfhosted any matrix servers yet, so i havent looked into it too much. I know that there are a few server implementations besides synapse that are mature and stable (and supposedly much more resource efficient) and they do support docker deployment.
