GrapesJS is a free, open-source (BSD 3-clause) framework that developers embed to give their users a drag-and-drop editor for webpages, emails and templates. Its maker also sells the Studio SDK, which has a free tier of 1,000 editor sessions a month and paid plans from $200 a month.

What it really is
An open-source JavaScript framework for building drag-and-drop page, email and template editors, plus a paid hosted SDK from the same team.
Our take
GrapesJS is the default answer when a product team needs a visual editor inside its own app and wants to own the code. The framework is free and permissive, the presets cover webpages and emails, and the JSON output keeps you portable. The cost is developer time: storage, UI polish and hosting are yours to build. The Studio SDK removes that work, but its pricing steps from free to $200 a month, so measure your editor sessions first.
Why we rate it
A free, permissive editor engine with real presets and clean export, backed by a paid managed option.
The catch
Self-hosting means building storage and UI yourself; the managed SDK jumps to $200 a month after 1,000 sessions.
Best for
SaaS products that need an embedded editor
Email and landing page template tools
Developers who want to own the output code
Not good for
Non-technical users building one website
Teams with no developer time
Friction report
Time to value
Minutes to load the demo; days to integrate storage and custom blocks.
Scale breakpoint
Passing 1,000 SDK sessions a month or needing custom branding.
Walled garden
Low: open-source core, JSON project data and HTML/CSS export.
