The 100x less code always reminds me of a hypothetical Half Life 2 game engine. Then your code would be:

   StartHalfLife2LikeGame()

and you'd replace millions LOC with one line. If there is a perfect match between the framework and your app, there is no code. The more your app diverges from the ideal app the framework was written for, the more code you have.

They claim that "Reddit, Slack, Gmail, Uber, etc" could also be done with a similar level of effort.

Yes, all applications that are aligned with the framework (message spreading from one user to many others) - not that I want to put down their effort in any way.

But this is the core [0] - a simple event location plattform my wife founded hat easily >200k LOC while the core (edit/search/detail page event location) had <10k LOC.

[0] If building Twitter I perhaps would try their setup, although I have been bitten with "magic" JVM frameworks in the past, e.G. we used one commercially and the license cost went up from 80k to 800k YoY. On top of scaling problems we could do nothing about because the framework was a black box.
