Grav (software)
Grav is a free software, self-hosted content management system written in the PHP programming language and based on the Symfony web application framework. It uses a flat file database for both backend and frontend.
Grav is designed to have a shallow learning curve, and to be easy to set up. The focus of Grav is speed and simplicity, rather than an abundance of built-in features that come at the expense of added complexity.
The name Grav is a shortened version of the word gravity.
Grav is the most starred PHP CMS on GitHub, with over 14,565 stars.
