Give your headless CMS a powerful drag-and-drop editor
GrapesJS fills the editor gap in headless architecture. It provides a rich visual interface that stores content directly in your headless CMS via API — while your frontend (Next.js, Nuxt, SvelteKit) fetches and renders independently. GJS.Market plugins handle the storage adapter plumbing so you can ship faster.
Headless editor architecture
Editor layer
GrapesJS provides the visual editing UI. Editors drag and drop blocks, customize styles, and publish — all inside your app.
Storage layer
Storage adapters send content to your headless CMS on save and load — REST, GraphQL, or custom API.
Content model
GrapesJS serializes to JSON — store the component tree, styles, and HTML in your CMS content model.
Delivery layer
Your frontend fetches from the CMS API and renders independently. The editor is invisible to end users.
Compatible headless CMSs
Any CMS with a REST or GraphQL API is compatible. The storage adapter pattern is CMS-agnostic.

Common headless CMS editor use cases
Marketing team autonomy
Let marketing teams create and publish landing pages without developer involvement, while keeping content in your headless CMS.
Multi-channel publishing
Publish structured content once and deliver it to web, mobile, and other frontends from a single headless backend.
Developer-built CMS UI
Replace the default CMS editing UI with a powerful drag-and-drop builder your team owns and fully controls.
Implementation blueprint
Configure storage adapters
Point GrapesJS storage manager to your headless CMS API endpoints for both load and save operations.
Define your content model
Map GrapesJS component types to your CMS content schema fields — blocks, rich text, media, and metadata.
Set up asset pipeline
Connect S3, Cloudinary, or your CDN for signed media uploads and optimized delivery.
Build preview and publish flow
Implement draft and publish states with live preview so editors can verify content before it goes live.
Quick start: connect GrapesJS to your CMS
// 1. Install GrapesJS and storage plugin
npm install grapesjs grapesjs-plugin-storage-rest
// 2. Configure headless CMS storage adapter
const editor = grapesjs.init({
container: '#editor',
storageManager: {
type: 'remote',
urlStore: 'https://your-cms.io/api/content/{id}',
urlLoad: 'https://your-cms.io/api/content/{id}',
fetchOptions: (opts) => ({
...opts,
headers: { Authorization: `Bearer ${token}` },
}),
},
});
// 3. Serialize to JSON for headless delivery
const content = editor.getComponents().toJSON();
await fetch('/api/cms/pages', {
method: 'POST',
body: JSON.stringify(content),
});Production readiness checklist
Coupled CMS vs headless with GrapesJS
| Aspect | Coupled CMS editor | GrapesJS + headless CMS |
|---|---|---|
| Frontend flexibility | Tied to CMS rendering | Any stack — Next.js, Nuxt, React Native |
| Editor control | CMS vendor decides UX | Full ownership and white-labeling |
| Multi-channel delivery | Complex or impossible | Native — one API, many frontends |
| Vendor lock-in | High | None — MIT license, swap CMS freely |
