The headless CMS architecture separates content from presentation. GrapesJS fills the editor gap — it provides a rich drag-and-drop editing interface that stores content in your headless CMS via API, while your frontend (Next.js, Nuxt, SvelteKit, or any stack) fetches and renders the content independently. GJS.Market plugins accelerate the storage adapter integration work.

Editor layer
GrapesJS provides the visual editing UI. Editors drag and drop blocks, customize styles, and publish — all inside your product.
Storage layer
Custom storage adapters send content to your headless CMS (Strapi, Contentful, Sanity, custom API) on save and load.
Content model
GrapesJS content is serializable to JSON — store the component tree, styles, and HTML in your CMS content model.
Delivery layer
Your frontend fetches content from the CMS API and renders it independently. GrapesJS is invisible to end users.
