WordPress

The world's most widely used open-source content management system and website creation platform, powering over forty percent of all websites on the internet. Released in 2003 under the GNU General Public License, the software has grown from a simple blogging tool into a full-featured web publishing platform used by individuals, small businesses, major media organisations, universities, and Fortune 500 companies. The platform's flexibility stems from its extensive plugin and theme architecture — a global community of developers has created tens of thousands of free plugins that extend functionality in virtually every direction, from e-commerce stores and membership sites to learning management systems and customer relationship management tools. Thousands of free and premium themes allow users to change their site's design with a few clicks, with modern themes supporting full site editing through a visual block-based editor that requires no coding knowledge. The block editor revolutionised content creation by treating every element of a page as a modular block that can be arranged, styled, and reused, making sophisticated layouts accessible to non-technical users. The open-source nature means the software can be freely downloaded, installed on any web server, customised, and redistributed without licensing fees. An active community of contributors maintains the core software, reviews plugin and theme submissions, provides support in forums, translates the interface into hundreds of languages, and organises global and local events. The platform is suitable for bloggers, small business owners, developers, agencies, and large organisations.
