Erlang web

Hello,

We currently use cowboy in our rest services and I like it a lot.
It's very fast, doesn't get in the way, has nice API and the code is very clean (I'm new to the language and use cowboy source code as a reference of how to do stuff properly in erlang).
I'm looking for a library or lightweight framework for implementing web applications on top of cowboy (ideally implemented in the same spirit).
So far I came across nitrogen and it looks interesting, but from its github it doesn't seem like it's being actively developed.
There's also N2O, but it's not clear how widely it's used and if there's any community around it.

Did I miss any options?

Thanks,
Sheldon
