Recently I have had the opportunity to play around with a database free CMS called GRAV. What a pleasure it is to code and use!
First of all it comes with an admin plugin, where I can publish new pages, view stats, edit content, upload images, basically everything a CMS with a database can do. I often forgot while working with GRAV that there isn’t a database driving it, which just shows how flawless the admin interface is.
Taken from the GRAV website below:
Grav is not your average CMS. It’s an open source, flat-file NoDB CMS written for PHP 5.5.9+ that is focused on being crazy fast, easy to learn and use, with powerful features to enable it be easily extended.
