I use it on a VM, I suggest you do it too.
I was a big proponent when they started as appear.in, but they’ve been steadily removing features (or moving them to the paid plan). For my friend group, the biggest appeal was that you could use it in a browser without an account by inventing a room name. That was one of the first features to get cut.
Everyone I’ve ever recommended it to has bumped into the limitations, asked me “what happened”, and switched to something else.
I haven’t tried it extensively, but I’ve read about https://meet.jit.si/ on HN and passed it on to a friend in that situation. He was happy with it and described it as “what appear.in used to be”.
