Genes Framework

You can easily create a multilingual simple static html website with it. You can create a blog in no time. Admin functions and user / membership actions are built in. It has a starter db structure.

The idea behind the DB is that you actually don't need to mess with the DB to get your MVP up and running. Just fit your model to starter DB structure, as no user actually cares whatever your DB, or backend, or frontend technology is. They care if it is smooth operating, fast and stable while being good looking and functional.

There are probably frameworks with loads of more features. But this is for you to get your MVP up and running in no time. Focused there.
