WordPress is a content management system (CMS) that allows users to build and maintain websites without coding knowledge. It was created in 2003 as a blogging platform but has grown to enable creation of many website types. WordPress.org is more powerful than WordPress.com and allows full customization. As open-source software, WordPress is free to use, has a large community creating tools for it, and gives users freedom to modify it as needed. WordPress can scale with users, from simple blogs to complex business websites.
