Grav - Overview
Grav is a flat-file based content management system. This system does not use database to store the content, instead it uses a text (.txt) file or a markdown (.md) file to store the content. The flat-file part refers to the readable text and it handles the content in an easy way which can be simple for a developer.
Grav was developed by the Rocket Theme team. It runs on PHP and is an open-source CMS like Joomla, Wordpress or Drupal.
Grav is now the fastest flat-file content management system. It is easier to publish and manage content with Grav. It allows a developer to handle content very easily by storing content in files (such as text or markdown files) rather than in database.
Grav helps you build a simple, manageable and a quick site. It costs less than the database driven CMS and is useful with I/O for file handling, when you don't have enough resources.

You might come across instances where unauthorized users may access your content from the files directly as there is no database for the files.
