# GrapesJS vs Editor.js: page building or document authoring

## Summary

- Editor.js is a document editor: a linear stack of typed blocks saved as JSON, with no layout, no breakpoints and no style controls.
- GrapesJS is a page builder engine: a canvas with layout, a style manager, responsive devices and HTML output, at 294.6 kB gzip against Editor.js's 64.3 kB in our measurements.
- If users are writing, choose Editor.js; if users are designing, choose GrapesJS — the failure mode is picking Editor.js for a landing page builder and rebuilding half of GrapesJS on top of it.

## The distinction that decides it

Write down what your users are producing. If it is an article, a help centre page, a product
description or a report, they are authoring a document and Editor.js is built for that. If it is a
landing page, an email or a template with columns and imagery arranged for effect, they are designing
a page and GrapesJS is built for that.

This sounds obvious and is routinely got wrong, because "block editor" and "page builder" sound
adjacent. They are not: one is a linear stack of typed content, the other is a two-dimensional canvas
with a style engine.

## Where Editor.js wins

**Structured output.** Saved content is typed JSON, so it is queryable, diffable and renderable to
any surface — web, native app, email, print. HTML gives you none of that.

**A fifth of the integration cost.** Five lines against fourteen in our benchmark, and 70 ms to a
rendered editor against 309 ms.

**A far smaller footprint.** 64.3 kB gzip against 294.6 kB, and the API is small enough to hold in
your head.

**Safer content handling.** Per-tool sanitisation and no arbitrary pasted markup reaching your
database.

**Users cannot break the design.** There is nothing to style, so an editor cannot produce an
off-brand page.

## Where GrapesJS wins

**Layout exists.** Columns, positioning, spacing and responsive breakpoints. In Editor.js, none of
these are configuration — they are features you would build.

**Users can style.** The style manager writes CSS. For a builder your customers use, this is usually
the requirement.

**HTML output, ready to publish.** No renderer to write, and the output works in contexts where JSON
blocks do not — email being the clearest.

**Email support through the newsletter preset**, where Editor.js has no path at all.

**Templates and blocks as a concept**, which is how end users actually start a page.

## The hidden cost of each

Editor.js's hidden cost is the renderer. Nothing turns your saved blocks into HTML; you write and
maintain one per surface, and keep it in step with tool versions. Teams underestimate this because
the editor itself was so cheap to install.

GrapesJS's hidden cost is the interface. The default panels are a developer tool, and making them
presentable to customers is a real project — see the
[screenshots in our benchmark](/research/time-to-first-editor-benchmark) for what "out of the box"
means.

## Migration

Editor.js to GrapesJS: render blocks to HTML with your existing renderer and import that. Workable,
lossy in the sense that structure becomes markup.

GrapesJS to Editor.js: only feasible for content that was already document-shaped. Anything with
layout does not survive the trip.

## Verdict

Document authoring: Editor.js, and be honest that a renderer is part of the project. Page building:
GrapesJS, and budget for the UI work. Some products genuinely need both — an article editor and a
landing page builder are different features, and using one library for both is the compromise that
satisfies nobody.

If the requirement is React-native document editing specifically,
[Editor.js vs Plate](/compare/editorjs-vs-plate) is the more useful comparison.

## Decision checklist

1. **Will users type paragraphs, or arrange sections?** Typing means Editor.js; arranging means
   GrapesJS.
2. **Does the same content need to appear on more than one surface?** Structured JSON blocks travel;
   HTML does not travel as well.
3. **Do users need to control appearance?** Editor.js gives them no styling at all, which is either
   the feature or the blocker.
4. **Who writes the renderer?** With Editor.js, you do, once per output surface, forever.
5. **Is email in scope?** Editor.js has no path to it; GrapesJS has the newsletter preset.

## The number that matters

Five lines of code and 70 ms to a rendered editor, from our
[benchmark](/research/time-to-first-editor-benchmark) — the lowest integration cost in this dataset.
It is genuinely impressive, and it is also the reason teams pick Editor.js for jobs it cannot do. The
cheapest library to install is not the cheapest to ship if the requirement is a page builder.


## Frequently asked questions

### Can Editor.js be used as a page builder?

Not without building a layout system, a styling layer and a renderer yourself, which is most of what GrapesJS already is. Editor.js has no columns, no breakpoints and no style manager in core.

### Which produces cleaner output?

Editor.js, unambiguously: typed JSON blocks rather than markup. But you write the renderer that turns those blocks into HTML for every surface you support.

### Which is lighter?

Editor.js, at 64.3 kB gzip against 294.6 kB for GrapesJS in our measurements — though the comparison flatters Editor.js, which does far less.
