Understand what WordPress.org software is, how the free open-source CMS works, and how it differs from the hosted WordPress.com service.
WordPress is a free, open-source content management system first released in 2003 by Matt Mullenweg and Mike Little as a fork of the b2/cafelog blogging platform. It is distributed through WordPress.org and licensed under the GPLv2 or later, meaning the software can be freely used, modified, and redistributed by anyone, including for commercial projects.
WordPress.org is not a hosting company or a paid product. It is the home of the open-source software project, offering the core CMS download, a directory of free themes and plugins, documentation, and community support forums. Anyone who wants to run WordPress must supply their own web hosting and install the software themselves, which is why this is often called self-hosted WordPress to distinguish it from the managed WordPress.com service.
This self-hosted model gives site owners full control over server configuration, custom code, and data, at the cost of needing to manage updates, security, and hosting relationships themselves rather than relying on a single managed provider.
The core WordPress software includes a block-based editor called Gutenberg for building pages and posts, a theming system for controlling site design, and a plugin architecture that lets developers extend functionality without modifying core code.
Its ecosystem includes tens of thousands of free and premium plugins covering ecommerce, SEO, forms, security, caching, and page building, alongside thousands of free and paid themes, making it possible to build nearly any type of website on top of the same core platform.
Because the software is open source, developers can inspect and modify any part of it, build custom plugins and themes, and avoid dependence on a single vendor for the platform's continued existence.
The WordPress software itself is entirely free to download, install, and use, with no licensing fees, subscription tiers, or seat limits, since it is released under the GPL open-source license.
Real-world costs come from elements outside the software: web hosting from a third-party provider, a domain name, and optionally premium themes, premium plugins, and developer or maintenance services.
This is a key difference from WordPress.com, which packages the same underlying WordPress software into a managed, paid hosting product with its own subscription tiers.
Yes, the WordPress software itself is free and open source. Costs come from separately purchased hosting, domains, and any premium themes or plugins.
WordPress.org distributes the free, self-hosted open-source software that you install on your own hosting. WordPress.com is a separate, commercial managed hosting service operated by Automattic that runs the same underlying software as a paid product.
WordPress was created in 2003 by Matt Mullenweg and Mike Little as a fork of the b2/cafelog blogging platform.
WordPress is released under the GNU General Public License version 2 or later (GPLv2+), which allows free use, modification, and redistribution.
Yes, self-hosted WordPress requires you to obtain web hosting from a third-party provider and install the software yourself.
Yes, WordPress supports ecommerce through plugins such as WooCommerce, which is widely used to turn a WordPress site into an online store.
WordPress powers a majority of all websites on the internet that run on a known content management system, making it the most widely used CMS.
Basic site building can be done without coding using themes and the block editor, but advanced customization typically benefits from developer knowledge of PHP, HTML, CSS, or JavaScript.
