Content is just simple markdown files in folders, with no complicated databases to deal with. A powerful API and extensive hooks allow for plugins to extend Grav and a comprehensive package manager provides easy installation and updating of extensions. Flexible Twig templating allows easy realization of your designs.
The website I used GRAV on is my personal project at http://www.becorklife.ie. There is a learning curve of course, but if you’ve managed Drupal or similar, the learning curve with GRAV is far easier. Basically all you are doing is learning the file structure and where template files are stored, what each .twig is doing etc.
It’s fabulous to see such innovation. It does feel that web development is returning to it’s roots, simple flat file structures, cut your cloth to fit the suit. Does every website need Wordpress, Textpattern, Drupal? Of course not. As web designers we should have a couple of tools under our belt and know which one is suitable for each job.
Keep websites fast loading, secure and search engine optimised (which includes mobile first responsive design).
