I use meet.jit.si (or a self-hosted version of the software) pretty reguarly and am a big fan. It's probably broadly comparable to other things people have suggested since it actually powers a lot of other video solutions behind the scenes, but I like their little demo service because it doesn't require auth and is pretty bare bones. Full disclosure: I was briefly on the Jitsi team.
