What is WordPress CMS

WordPress is a content management system, commonly called a CMS from the English Content Management System, created in 2003 as a simple platform for managing blogs and over time becoming the most widely used tool in the world for building websites of all kinds. Initially developed by Matt Mullenweg and Mike Little as an evolution of an earlier project called b2/cafelog, WordPress is distributed free of charge as open-source software under the GPL license, meaning anyone can download it, use it, modify it and redistribute it freely. This openness has played a decisive role in its global spread, attracting a community of developers and designers who over the years have created thousands of themes, plugins and extensions.

What made WordPress so popular is its accessibility: it allows anyone, even without technical programming knowledge, to create and manage a website independently. Through an intuitive administration interface, users can publish articles, manage pages, upload images, install plugins to add features and completely change the appearance of the site simply by switching the graphic theme. This flexibility has led WordPress to be adopted not only by bloggers and small businesses, but also by major news organizations, multinational companies and public institutions. Today it is estimated that around 40% of all existing websites in the world are built on WordPress, a figure that gives an idea of its extraordinary reach.

WordPress exists in two distinct versions worth knowing: WordPress.com, the hosted version that offers an all-in-one service where the site is hosted directly on Automattic’s servers, and WordPress.org, the self-hosted version where the software is downloaded and installed on your own hosting service. The latter is the version most used by professionals, because it offers maximum freedom and customization without limitations. Despite competition from more modern platforms such as Webflow or Squarespace, WordPress continues to dominate the market thanks to its huge ecosystem, highly active community and ability to adapt to any type of project, from a simple personal blog to a complex e-commerce platform or a news portal with millions of monthly visitors.
