WordPress
WordPress is an open-source content management system (CMS) that powers a large share of the web, letting site owners edit pages and posts through an admin dashboard and extend the site with themes and plugins.
WordPress is flexible and widely supported, which makes it a common choice for small business sites, blogs, and content-heavy sites. Most features come from plugins, and the look of the site comes from a theme.
That flexibility has tradeoffs. Outdated plugins are a common entry point for hacks, plugin conflicts can break a site after an update, and too many plugins can slow it down. Regular updates and backups prevent most of these problems.
