WordPress is an open-source content management system that's one of the most popular blogging tools. WordPress was originally built as a fork of the early blogging platform b2. Today, while it's still primarily designed for publishing blogs, WordPress is used as the CMS behind standalone sites, eCommerce stores, and more, powered by WordPress' content tools along with plugins that let you customize WordPress into anything you want.

You can run WordPress on your own server, with one-click installs offered on hosts like DigitalOcean and Amazon Lightsail. Or, you can use the hosted version of WordPress on WordPress.com to start a free blog then upgrade to add additional features and add-ons.

WordPress is popular for its flexibility, with an active ecosystem of themes and add-ons to build the site you want. That flexibility also means WordPress includes more features than a blog may need, and can make WordPress sites slower and more difficult to secure.

• Run a blog. WordPress is built to help bloggers publish content regularly, with a clean rich-text writing environment and settings to queue posts in advance.
• Edit content pages without code. You can use the same blogging tools to edit any page on your site, making WordPress an easy way to let anyone on your team maintain content and add new features.
• Add features with plugins. Build your site into anything you want with WordPress plugins to add an eCommerce store, build forms, and more.
• Publish content as a team. Invite your team to your WordPress site so everyone can add posts, edit content pages, and more without coding.
• Tweak anything. WordPress is open source, so you can change its code, access your MySQL content database from other tools, and use WordPress as a base to build a custom CMS.
• Build a community. WordPress includes a built-in commenting system, with Akismet spam protection and options to moderate comments as they come in. Your site can also let other WordPress sites know when you've mentioned them and show Trackback backlinks to build a community of blogs across the web.
• Publish on the go. WordPress' mobile apps and integrations with popular writing software let you write and publish from anywhere. Its integrations also let you automate publishing, and share your content elsewhere.
