WordPress is a free and open-source content management system written in PHP and paired with a MySQL or MariaDB database. Features include a plugin architecture and a template system, referred to within WordPress as Themes.
WordPress powers more than 39% of the web — a figure that rises every day. Everything from simple websites, to blogs, to complex portals and enterprise websites, and even applications, are built with WordPress.
WordPress combines simplicity for users and publishers with under-the-hood complexity for developers. This makes it flexible while still being easy-to-use. The following is a list of some of the features that come as standard with WordPress; however, there are literally thousands of plugins that extend what WordPress does, so the actual functionality is nearly limitless. You are also free to do whatever you like with the WordPress code, extend it or modify in any way or use it for commercial projects without any licensing fees. That is the beauty of free software, free refers not only to price but also the freedom to have complete control over it.
