Quick facts
- WordPress was launched in 2003 by Matt Mullenweg and Mike Little as a fork of the discontinued b2/cafelog project.
- It is free software released under the GNU General Public License.
- The theme and plugin ecosystems allowed users to change design and add features without modifying the core code.
- WordPress.com is a hosted service, while WordPress.org distributes the self-hosted open-source software.
- By 2026, WordPress powered roughly two-fifths of websites and continued its transition toward block-based site editing.
Origins and founding
WordPress began when developer Michel Valdrighi stopped updating the b2/cafelog blogging software. Matt Mullenweg wrote in January 2003 that he wanted to create a fork with better standards and features. British developer Mike Little responded, and the two began working on the project.
The name WordPress was suggested by Christine Selleck Tremoulet. Version 0.7 launched on May 27, 2003. Because it inherited b2’s code under the GPL, WordPress could evolve as a community-owned open-source project rather than a closed commercial product.
The product takes shape
Early releases introduced clean links, categories, comments and easier installation. Version 1.5 in 2005 added a theme system and the default Kubrick design. Plugins allowed independent developers to extend the software with contact forms, search optimization, security, commerce and nearly every other website function.
Automattic, founded by Mullenweg, launched WordPress.com as a hosted service and built commercial products around the ecosystem. The independent WordPress Foundation later protected trademarks and the open-source mission. The project’s frequent releases and volunteer contributor events strengthened global participation.
Technology and major features
WordPress is written primarily in PHP and typically stores content in MySQL or MariaDB. Its template hierarchy determines which theme files display different pages. Hooks allow plugins to add or change behavior without editing core files. A REST API enables external applications and headless front ends.
The Gutenberg editor, introduced in WordPress 5.0 in 2018, represented content as blocks such as paragraphs, images and galleries. Full Site Editing extended blocks to headers, footers and templates. WordPress 7.0 in 2026 continued this modernization with collaboration and editing improvements.
Growth and wider influence
WordPress lowered the cost of publishing and gave individuals control over their own websites. Blogs, news organizations, universities, governments, businesses and online shops adopted it. WooCommerce turned WordPress into a major commerce platform, while hosting companies built large businesses around installation and support.
Its open ecosystem supported local-language communities around the world. A beginner could publish without programming, while an expert could build a custom application on the same core software.
Challenges, criticism and responsibility
Popularity makes WordPress a major security target. Vulnerabilities often occur in outdated third-party plugins or themes rather than the core, but site owners may not distinguish among them. Poor hosting, weak passwords and abandoned extensions increase risk.
The ecosystem also faces governance disputes involving trademarks, commercial companies and project leadership. The transition to blocks divided users who valued the classic editor from those seeking a modern visual system. Openness creates choice, but it can also create inconsistent quality and fragmented responsibility.
Where it stands in 2026
By 2026, WordPress remained the most widely used content-management system, powering around 43 percent of websites according to project and market measurements. The roadmap emphasized collaborative editing, multilingual capabilities, performance and a more unified block-based design experience.
Its future depends on preserving user ownership while making the platform simpler and safer. AI writing and design tools may become common, but WordPress’s lasting advantage is that the publisher can control the site, data and hosting instead of being locked entirely inside a social platform.
