WordPress is an open-source Content Management Framework (CMS) designed originally as a blogging tool. Built on PHP and MySQL, WordPress offers a highly extensible architecture with over 30,000 plugins and a template system to create seemingly infinite types of themes. Its core installation comes with a centralized dashboard, stock themes that are mobile-responsive and customizable, powerful administrative capabilities, an SEO friendly permalink structure, and a WYSIWYG editor, among other features. WordPress boasts an active user and developer community, and its popularity has led to a thriving business ecosystem of theme designers, plugin authors, and web hosting services. Automattic, WordPress’ sponsor, maintains an active presence in the community, offering the framework’s most popular anti-spam plugin Askimet and a free WordPress.com blogging service, as well as other amenities.
