Yeah it's pretty awesome. My only gripe with it is the fact that it is super annoying when you want to send a client with your self-hosted urls to a customer.
You can either awkardly add it to the filename or you need to fork the client and build it yourself. Kind of sucks that the easier custom client function is stuck behind their subscription.
authentication is also stuck behind their subscription. for random customers to be able to use your servers, you also have to let everyone else on the internet use it.
