Headless CMS
Noun · Development
Definitions
A content management system that provides content via API without a built-in frontend presentation layer. Content is managed in the CMS and consumed by any client — web, mobile, IoT. WordPress without the themes.
In plain English: A system for managing content (articles, images, etc.) that delivers content through an API instead of building the website itself — letting developers build the frontend however they want.
Popular headless CMS platforms include Contentful, Strapi, Sanity, and Payload. The tradeoff vs. traditional CMS: more developer flexibility but no built-in frontend, meaning content editors can't preview their changes without custom tooling.
Example: 'Content editors write in Sanity, the website pulls content via API, the mobile app pulls the same content. One CMS, multiple frontends — that's the headless advantage.'
