Headless CMS

A Headless CMS (Content Management System) is a backend-only content management platform that separates the content creation and management process from the presentation layer. Unlike traditional CMS platforms, which are tightly coupled to a front-end display, a headless CMS allows content to be delivered to multiple channels (e.g., websites, apps, or IoT devices) via APIs. This flexibility supports modern, multi-platform digital experiences.

A headless CMS is the right architectural choice when your content needs to appear in multiple contexts — a website, a mobile app, an email newsletter, a digital billboard — because you manage content once and deliver it everywhere via API. For marketing-led SaaS companies with multiple content channels, or companies planning to build native mobile apps alongside their web product, going headless early avoids expensive migrations later.

Contentful is used by companies like Spotify and Intercom as a headless CMS — content editors manage blog posts, product docs, and marketing pages in Contentful, which delivers that content via API to their website, mobile apps, and even in-product help panels, all from a single source of truth.
