Thanks for sharing these resources! Regarding your last point stating that "these technologies are at least a great way to prototype a backend.":

We've taken this feedback extremely seriously and are extracting the core of Graphcool as a standalone component which is a "GraphQL database". While it's not as user friendly (as of a visual user interface) it's meant as a foundation for highly scalable systems (based on the architectures you might find at Twitter or Facebook).

I'm very happy to hear more of your concerns and answer any questions!
