There are many make your own RPG sites but the best you can find for airline games is make your own world.
With AE4 nowhere near completion, this is probably a better alternative mode of development.
What we need is:
- Server side sandbox. Docker?
- Persistent object module, programmers should not use SQL / noSQL directly.

- Client side sandbox. iframe / webworker?
- UI API, since client side code is sandboxed, it needs a way to interact with players.
Anything else?
