originally created as a tool to publish blogs but has evolved to support publishing other web content, including more traditional websites, mailing lists, Internet forums, media galleries, membership sites, learning management systems, and online stores. Available as free and open-source software, WordPress is among the most popular content management systems – it was used by 22.52% of the top one million websites as of December 2024.[4][5]

WordPress is written in the PHP Programming Language[6] and paired with a MySQL or MariaDB Database. Features include a plugin architecture and a template system, referred to within WordPress as « Themes ».
