This is slick! Looks pretty polished. I'm interested to figure out how they enable channel creation and management. I'm assuming this is just listing all the channels on the server and the instance doesn't federate?

I'm also always curious when there is an open source product like this that has a free self hosted version that they say is user capped at 20 users. How? Is that just an arbitrarily string of code inserted someone that can be easily stripped out? I see some forks so could be.
