There are many powerful open source CMS solutions for building complex websites. Some of the more commonly used ones are Joomla, WordPress, and Drupal. The downside of these platforms is that they have a steep learning curve associated with them. This requires a significant amount of your time – and this may be the time that you do not have.
These platforms provide a wealth of features and functionality that you can extend with a wide variety of open source and proprietary plug-ins and themes. These extensions and themes are themselves often feature-packed, requiring more knowledge and time on the part of the developer yet.
In the end, you often find yourself creating a website that requires many plugins and extensions from many different vendors. This can make your design overly complicated and difficult to maintain over the long term.
Grav tackles the problem differently. It focuses primarily on your content and turns your content structure into a navigable site. The underpinnings of Grav are simple, yet via extensive events, you have complete control over every step in the Grav workflow.
This solution allows simple plugins to quickly and easily add powerful functionality. Using Grav CMS also leads to a rapid development environment with an installation process that takes seconds, including a straightforward content creation method with a minimal learning curve. All of this contributes to making Grav friendly to the designer, the developer, and the end user.
To get a basic site up-and-running requires minimal Web development experience. If you dig a little deeper, you will discover that there is very little Grav cannot accomplish.
Grav CMS requires PHP 7.3.6 or higher, with these extensions enabled curl, ctype, dom , gd, json , mbstring , openssl, session, simplexml, xml , and zip. The project is very well documented, and you will find out detailed explanation on how to install, configure, customize and use the CMS.
