Hva er Headless CMS?
Rask definisjon
Et Headless CMS er et innholdsstyringssystem som skiller backend fra presentasjon og leverer innhold via et API til enhver enhet eller plattform.
A headless CMS separates content management from content presentation. Unlike a traditional CMS where the backend (where you write content) and the frontend (what visitors see) are tightly coupled, a headless CMS only handles the backend. It stores and manages content, then delivers it through an API to whatever frontend you choose.
This decoupled architecture means the same content can be displayed on a website, a mobile app, a smart TV, a kiosk, a smartwatch, or any other device. You write the content once, and it can appear anywhere. This is why headless CMSs are also called "API-first" content platforms.
Popular headless CMS platforms include Contentful, Strapi, Sanity, Prismic, and Storyblok. Some traditional CMSs like WordPress and Drupal also offer headless modes, exposing their content through APIs while letting you build custom frontends.
The "headless" name comes from the analogy of removing the "head" (the frontend/presentation layer) from the CMS "body" (the content backend). Developers then build the head separately using whatever technology best fits the project, whether that's Next.js, React, Vue, or even a mobile app framework.
Hvorfor det betyr noe
Headless CMSs provide maximum flexibility. As businesses publish content across more channels (website, app, email, social, IoT devices), managing content in one place and distributing it everywhere becomes essential.
For development teams, headless CMSs allow using the best frontend technology for each project without being locked into a specific CMS theme or template system. This typically results in faster, more modern websites with better user experiences.
