You can set up your own blog website on any server that supports PHP and MySQL. Thousands of plug-ins and countless theme templates are available for WordPress and easy to install.

WordPress is a blog platform developed in hypertext preprocessor (PHP). You can set up your websites on the services that support PHP and MySQL databases, or use WordPress as a content management system. For more information about WordPress, visit https://wordpress.org/.
