For a beginner who wants to build a simple chat app, and doesn't want to waste time learning how to develop a backend and secure it, what could be the best BaaS?
When I was googling I came across several services such as Firebase, and I liked it, it's very easy to use and well documented, but the sad part is that the user must be active to receive messages it doesn't support push notifications. And most of the others (like Buddy) is very costly.
Please share your thoughts.
