Have you ever used Strapi Node.js framework in development or production?

I've found this new NodeJS Framework and looks awesome for 2 reasons: is Front-end and Database agnostic!

This framework is built on top of KoaJS and for me is awesome because i hate the callback hell. Currently, I'm working with KoaJS on a micro-private framework really similar to Strapi but without a bunch of features ( yield <3 ! ) So, I would like to have some feedback before I start making something based on it !
