SafariHow they compare
The fork is: do you want to edit the design inside your code editor (Cursor's mode), or on the actual rendered page in your browser (Design Mode)? The answer depends on which surface gives you more context.
Feature-by-feature
| Feature | Design Mode | Cursor's built-in design mode |
|---|---|---|
| Visual editing on a scriptable webpage | Yes — typography, colour, layout, spacing, motion and effects on localhost, staging or production pages the extension can script. Browser-protected pages are excluded. | In-editor design surface |
| MCP (Model Context Protocol) handoff to AI agents | Yes — Cloud, Local, and Self-hosted modes; eight common session tools, plus Local feedback rounds | Native to Cursor |
| Persistent change history (Changes tab) | Yes — searchable, filterable, exportable | Editor history |
| Open source | Yes (MIT) | Proprietary |
| Price | Free MIT-licensed extension | Cursor subscription |
| Markdown / JSON export of the diff | Yes | Code changes in editor |
| Best fit for | Designers, developers, QA, PMs, content, indie hackers, agencies, vibe coders | Cursor power users |
When to pick Design Mode
- You want to edit on the rendered page, not in a code-adjacent surface.
- You want real device pixels, real fonts, real hover/focus/animation states.
- You're testing across multiple pages or staging deploys.
When to pick Cursor's built-in design mode
- You stay inside Cursor all day and don't want a second tool.
- Your edits are local-only and never touch a deployed surface.
Honest take
Cursor's mode is great for in-editor work. Design Mode is great when you want the canvas to be the actual rendered page. Many people use both.
