This is literally a themed Jitsi instance. Even fetches its assets from Jitsi's CDN, lol

I used jitsi for a long time. Then they started throttling and then they demanded user registration. I ditched them at that point and started using this. What you say it's maybe true, didn't checked, but for above reasons I gave up on them. Each to their own I suppose

The maximum of 4 users can be a bit limiting.
