WordPress is an open source content management system (CMS) with a database of millions of articles, blogs, and other web content. WordPress is also a popular platform for creating custom web applications and websites.
AMP (Accelerated Mobile Pages) is a content delivery network (CDN) that helps make webpages load faster on devices with low bandwidth, such as smartphones and low-powered tablets. AMP works by caching the HTML and CSS of a webpage on the AMP server, then serving the cached page directly to the browser.
AMP is free to use for any website or web application, and the WordPress AMP Plugin is available free of charge from the WordPress.org website.
