Re: Parse.com
in my view, no-backend do work but only in greenfield. It's not that hard to build app to solve a problem people have even in an environment with many constraints like, AWS Lambda, Firebase or what used to be Parse.com (RIP).
But that is greenfield only. Try to integrate that with an existing technology stack if you have one and I'm sure you not gonna have a good time.
Only feasible way (does not break your mind or budget) Is to add rest end point to existing data sources and only integrate them at the view layer. Meaning just present the data in the UI like it was coming from one source while it actually is not.
