Really awesome! Was looking for something like this.

This looks really nice!

Depending on what exactly you're trying to build, Rails has a neat feature for creating 'scaffolds' (templates if you will) which have simple crud operations, a model and views for displaying information. Search Rails scaffold examples. Happy hacking!

I'm searching for a website, where I can select what features I would like to have in my app, and select backend type (for example django) and website will generate a template backend - is it even possible?

In particular, I'm searching for django templates.
