What is Contentful?
A content management system that enables cross-platform, multi-device online publishing. Businesses employ Contentful to publish editorial content for web apps, mobile apps, and, ultimately, any connected devices.
Contentful is 1) a backend for content delivery, 2) an API for fetching and manipulating the content, and 3) a web app in which editors create and organize the content. The full stack for modern publishing.
Contentful is different from the majority of established web CMSs, as it keeps content separated from its presentation and delivers content via an elegant RESTful JSON API, empowering developers to build highly custom user experiences.
