WordPress

WordPress is the most widely used content management system, which allows users to create websites and manage content via a user interface. According to W3Techs, WordPress powers about 40 percent of all websites (as of October 2026). The software is open source—meaning it’s freely available—and is used for corporate websites, blogs, landing pages, and, with extensions, online stores as well. Plugins (extensions) and themes (design templates) customize functionality and appearance. How fast and secure a WordPress website is depends on its implementation, hosting, and regular updates.
