What is Headless CMS?
A content management system that stores content via API but has no opinion on how the content is rendered — your frontend is separate.
Traditional WordPress is a 'coupled' CMS: the same software stores content and renders pages. A headless CMS (Sanity, Contentful, Strapi) only stores content and exposes it via API; you build the frontend separately. Why decouple: you can swap frontends without re-migrating content, your editorial team and your engineering team work in the right tools, and your site stack stays modern. InBuild plays well with headless CMS — export a Next.js project, then wire it to Sanity or Contentful for long-form editorial content while keeping InBuild's components for layout.
