I've been using the docs tool in my homelab for ~3 months now as a knowledge base for some projects I've been working on with some friends.

It's really good. The typing experience "feels" right and the collaboration features work. I haven't played with the other solutions yet but I'm very excited if they are up to the same standard.

I deployed it with docker and it was relatively smooth. I had to play a bit with the OIDC but I'm pretty sure that was more a me issue than anything.
