It's a full stack framework. Node js backend, choice of db extensions (starts with redis I believe), and js front end.
Runs on handlebars.
For someone like me, who's used to the standard LAMP stack and hasn't played with Node, any of the js frameworks, redis, or handlebars, it took a few days to get acquainted, but once I did I really enjoyed using it.
Again, a little too much magic, which makes me feel like my code is weak.
