The worlds most popular open-source CMS
WordPress is the open-source CMS behind a large share of the web. It runs everything from blogs and marketing sites to e-commerce (via WooCommerce) and fully custom builds, with total control when self-hosted.
Highlights: thousands of themes and plugins, the block-based Gutenberg editor, headless via the REST API, and a huge developer ecosystem. Maximum flexibility for teams that want to own their stack.
