What is Headless architecture? Definition and explanations
A headless architecture separates content or data management from its display. The back office exposes APIs; one or more front ends — website, mobile app, kiosk, assistant — consume those APIs and decide how to render. The benefit is reusing the same content across channels; the cost is building and maintaining each front end separately.
In one sentence
A headless architecture separates content from display and serves it to multiple channels through APIs.
