Just, for my situation, I am not sure why I need to pay for that functionality when I can literally set it up in one day vs reading the documentation on how to set it up on Firebase in the same time.
I also control all outcomes and avoid ones like this where Google could potentially take over control of a large portion of your app.
My server side code is about 100 lines. This controls a chat server, chat rooms, youtube video commands. And its currently working just fine with 4,000 visitors a day on a vps that cost $5 a month.
Why not learn how to do it yourself? Especially if you already have vps. I am using varnish with multiple sites and it took a couple hours to set up. I am really confused on this.
