Build a No-Code Website Builder with GrapesJS

You are not installing a page builder. You are adding a no-code editing feature to a product you already own — with your users, your permissions, your data and your publishing. The visual editor is one layer of that, and it is the layer you do not have to write.

Every layer above and below the engine is your product. That is where your differentiation lives — and it is where your engineering time should go.

The single most useful thing to settle before you write any code: which subsystem belongs to your application, which ships with the editor, and which you can buy off the shelf. Anything that needs a server is on the left.

Nothing that requires a server is listed under GrapesJS. The editor runs in the browser; it has no notion of who is signed in.

A visual editor looks like a drag-and-drop demo until you ship one. These are the subsystems that turn out to be mandatory, roughly in the order a user's gesture travels through them — and each one has to keep working while all the others change.

• 01A drag-and-drop canvas with valid drop targets and nesting rules
• 02A component system with types, defaults and per-type behaviour
• 03DOM manipulation that survives arbitrary user structure
• 04Style management that writes real CSS, not inline soup
• 05Responsive editing across breakpoints
• 06Undo / redo over every one of the above
• 07A block palette users can actually reason about
• 08Reusable components that update everywhere at once
• 09Asset management: upload, browse, replace, delete
• 10A layer tree for selecting what a mouse cannot reach
• 11A command system so features are addressable and scriptable
• 12Persistence that does not lose an hour of work
• 13Serialization stable enough to reload and to diff
• 14Preview that matches what a visitor will see
• 15Publishing that produces clean, deployable output
• 16Custom UI, because the default panels are never your product
• 17A plugin architecture, or the whole thing calcifies

None of that is your product. Building the product around an existing editor engine is a fundamentally different project from building the editor engine itself — the first ships a feature, the second commits a team to maintaining an editor forever.

GrapesJS is an open-source visual editor framework you self-host and embed. It gives you the editing layer — canvas, components, styling, panels, commands — as documented modules you configure, extend or replace. Every module below links to its own documentation, so you can check each claim before you commit.

• Canvas↗documentation (opens in a new tab)The live editing surface your users manipulate directly.
• Components↗documentation (opens in a new tab)Typed nodes you define: a Pricing Card can behave differently from a paragraph.
• Block Manager↗documentation (opens in a new tab)The palette. You decide exactly what appears in it, per user.
• Style Manager↗documentation (opens in a new tab)Style sectors and properties — restrict it to your design tokens.
• Trait Manager↗documentation (opens in a new tab)Per-component settings fields: link targets, alt text, ids.
• Asset Manager↗documentation (opens in a new tab)Image browsing and upload, pointed at your own storage.
• Storage Manager↗documentation (opens in a new tab)A client of your API. Load and store project JSON on your endpoints.
• Layer Manager↗documentation (opens in a new tab)The component tree, so nested structure stays selectable.
• Commands↗documentation (opens in a new tab)Every action is a named, callable command you can add to.
• Panels↗documentation (opens in a new tab)Add, remove or rebuild the editor chrome entirely.
• Device Manager↗documentation (opens in a new tab)Your breakpoints, not arbitrary widths, on the canvas.
• Plugins↗documentation (opens in a new tab)A documented extension point — the seam the marketplace plugs into.

Version 0.23.6, licensed BSD-3-Clause; the official React wrapper @grapesjs/react is MIT. Both permit commercial use. What GrapesJS does not ship is equally important: no backend, no users, no permissions and no publishing pipeline — see the responsibility boundary above.

A professional no-code builder never exposes the whole editor to every user. That is the difference between a toy and a product feature. Your team decides — per role, per template, per component — how much of the editor a given person can reach.

const editor = grapesjs.init({
  container: '#editor',
  // 1. The user only ever sees blocks you registered.
  blockManager: { blocks: approvedBlocks(user.role) },
  // 2. The Style Manager only offers properties you allow.
  styleManager: { sectors: allowedSectors(user.role) },
  // 3. Devices are your breakpoints, not arbitrary widths.
  deviceManager: { devices: BRAND_BREAKPOINTS },
});

// 4. Lock the chrome: a marketer never edits the header or the footer.
editor.on('component:add', (component) => {
  if (LOCKED_TYPES.includes(component.get('type'))) {
    component.set({
      editable: false,
      draggable: false,
      removable: false,
      copyable: false,
    });
  }
});

// 5. Hide panels this role has no business seeing.
if (!user.can('edit_code')) {
  editor.Panels.removeButton('options', 'export-template');
}

// Every line above is a RENDERING decision. The server still checks
// user.can('publish') before it accepts the payload.

You do not need three editors to serve three kinds of user. One GrapesJS instance, configured from the signed-in user's role, produces three genuinely different products. Each column below lists what it adds to the one before it.

1. 1Beginner

   Fill in the page

   For people who have never opened a design tool and never should have to.

   • Edit text in place
   • Replace images from the asset library
   • Drop in approved blocks
   • Reorder sections within a template
   • No style panel at all
2. 2Marketer

   Build the page

   Adds everything a campaign owner needs to ship without a developer.

   • Create new sections from scratch
   • Start from templates
   • Adjust layout and spacing
   • Check and fix responsive behaviour
   • Edit approved styles within your tokens
3. 3Power user

   Design the system

   Adds the controls an in-house designer or agency operator expects.

   • Advanced components: tables, sliders, forms
   • Free-form layout controls
   • The full Style Manager
   • Save reusable symbols and templates
   • Custom classes and states

The configuration is data, not code. Which means the difference between your Starter plan and your Enterprise plan can be a row in a table.

The fastest way to make a visual editor safe is to give it nothing unsafe to offer. Feed your tokens into the Style Manager and your components into the Block Manager, and "off-brand" stops being a review problem — it becomes unreachable.

A blank canvas is not freedom, it is a blank stare. The single biggest driver of whether non-technical users succeed in your builder is whether the first thing they see is a curated set of sections that already look like your product.

• Hero

  Headline, sub-line, one call to action.

• Features

  Two to four column feature grid.

• Pricing

  Plan cards wired to your own plan data.

• Testimonials

  Quote, attribution, optional logo.

• FAQ

  Question and answer pairs.

• Call to action

  One message, one button.

• Contact

  Form fields posting to your endpoint.

• Footer

  Usually locked, always present.

Editing and publishing are different actions with different risk profiles, and a production no-code product separates them. The two gated stages below are where an authorization check belongs — not in the editor, in your API.

Permissions, approvals and publishing logic belong to the application and its backend. GrapesJS has no concept of a draft, an approval or a live URL — those states live in your database, and rollback is simply publishing an earlier revision.

Four roles cover most builder products. Each one gets a genuinely different editor because each one loads a different configuration — but every one of them is enforced in the same place: your backend.

This table is deliberately narrow: it compares the editing engine only. Everything on the responsibility boundary marked "your application" is your work either way — that is the point.

White-labelling is not hiding a logo. It is making the editor read as a feature of your application rather than as a third-party tool someone embedded in it.

• Custom branding

  Your colours, type and iconography throughout the editor chrome.

• Custom panels

  Rebuild the toolbars around your users' actual tasks.

• Custom components

  Your design system's components, named the way your team names them.

• Custom terminology

  If your users say "module", the editor should not say "component".

• Less UI, not more

  Removing controls is the most under-used customisation there is.

• Controlled experience

  Defaults, empty states and onboarding that match the rest of your product.

Removing the GrapesJS branding is trivial and permitted by the BSD-3-Clause licence. Making the editor feel like your product is a design project — panels, terminology, defaults, and everything a user does not see.

GrapesJS renders into a plain DOM element, so integrating it is mostly a question of which lifecycle hook calls `grapesjs.init()` and when it is cleaned up. Pick your framework for the specifics.

• React

  An effect that initialises on mount and destroys on unmount. The official @grapesjs/react wrapper (MIT) is available if you want the editor's own UI as React components.

  See React integration

• Vue

  A composable calling init from `onMounted` and destroy from `onBeforeUnmount`. There is no official Vue wrapper — you call the same API directly.

  See Vue integration

• Angular

  A component using `ngAfterViewInit` and `ngOnDestroy`, with the editor kept outside Angular's change detection. No official Angular wrapper exists.

  See Angular integration

• Next.js

  Client-side only: the editor touches `window` at module scope, so load it through a dynamic import with SSR disabled.

  See Next.js integration

Your framework powers the application. GrapesJS powers the visual editing layer.

The gap between "the editor works" and "we can put customers on it" is roughly this list. Each group links back to the section that argues it.

A no-code builder is, by construction, a feature that lets users put arbitrary content into your product. Treat everything it produces as untrusted input, because it is.

• Sanitize published output

  Run produced HTML and CSS through a vetted sanitizer on the server before it is stored or served.

• Validate uploaded assets

  Check type, size and dimensions server-side, and serve user media from a separate origin.

• Enforce permissions in the backend

  Every save, approve and publish is authorized again on the server, whatever the editor showed.

• Never trust client-side authorization

  A hidden panel is a UI state. The editor's API is still reachable from a browser console.

• Validate stored project data

  Project JSON is user input too. Validate its shape before you feed it back to a renderer.

• Control custom code execution

  If you allow a custom-code component, decide deliberately where it runs and who may add one.

• Protect publishing endpoints

  Rate-limit them, scope them per project, and log every call.

GrapesJS is an editing library, not a security boundary. It makes no guarantee about the safety of the markup it produces, and it cannot: the markup came from your user. Sanitization, validation and authorization are your application's responsibility.

The editor is a heavy client-side application living inside your product. Most of the wins come from not loading it — and from not loading it twice.

• Initialise on demand

  Boot the editor when a user opens it, not when the route loads.

• Lazy-load optional features

  Dynamic-import plugins the current role can actually use.

• Load only the plugins you need

  Every registered plugin costs bundle size and start-up time forever.

• Keep the block catalogue curated

  Hundreds of blocks slow the palette down and paralyse the user.

• Optimise assets

  Resize and re-encode on upload — users will drop 8 MB photos into a hero.

• Debounce autosave

  One write every few seconds, not one per keystroke.

• Watch project size

  Inlined base64 images turn a project row into megabytes. Store references, not data.

The published page must never carry the editor. A visitor loads HTML and CSS; only an author loads the engine.

AI in a page builder is most useful, and least dangerous, when it is treated as another user of the same editor — one that can only produce what a human in the same role could have produced.

• Generate sections

  Assemble a section from your registered blocks, not from free-form markup.

• Generate copy

  Fill an existing layout's text nodes, leaving structure untouched.

• Suggest layouts

  Propose an arrangement of approved components for a stated goal.

• Transform content

  Rewrite for length, tone or locale in place.

• Generate components

  Draft a new component definition for a developer to review — never to auto-register.

• Optimise existing pages

  Suggest edits against measurable criteria and let a human approve them.

AI should operate inside the same component and design-system constraints as human users. If a generator can emit arbitrary HTML that your block palette would never offer, you have re-opened every hole you closed.

The capabilities above describe a pattern you can build on the editor's own APIs, not a shipped GJS.Market feature. The catalogue does have an AI shelf — thumbnail generation, GPT-backed helpers — and it is linked above.
