I'm pretty sure there isn't such a thing for Elixir.

And quite possibly there won't be something like it anytime soon, if ever. I get the impression that the Elixir 'ecosystem' is a bit more modular/manual in approach even when you compare Phoenix to Rails, which means, with all else being equal, a bit less of an out-of-the-box experience.

Of course in part this is because there are currently just fewer packages available for Phoenix. But I think it's also inherent to the 'culture'. It might never be as cookie-cutter in what it offers.

(but I'm still relatively new to the Phoenix/Elixir world, so I could be entirely wrong)
