How it works
Describe your product's UI, paste in your branding, and drop in realistic mock data. No screenshots needed — just describe what it looks like.
Claude generates a self-contained JSX component with live interactions, real-looking data, and your exact visual style. Edit it freely.
Open the live preview in Sandpack, screen record it, and ship. Your demo looks production-grade because it basically is.
Features
Describe your product and get a pixel-perfect React component — not a screenshot, an actual interactive UI with state and hover effects.
Sandpack renders your component in a secure sandbox right in the browser. No build step, no local setup, no waiting.
Seeded with plausible names, numbers, and states. No lorem ipsum, no obviously fake data, no awkward blanks.
Pass your color palette, typography, and component style — the output matches your design system, not a generic template.
Copy the JSX, download the component, or embed the Sandpack preview. Fits into any recording workflow.
Create different demo flows for sales, onboarding, or investor pitches — each with its own state, data, and feature focus.

FAQ
No. DemoDonkey generates demos from descriptions and mock data you provide. You never expose your real backend, database, or source code. The output is a standalone JSX component with seeded fake data.
It's a standard React component with Tailwind CSS styling. You get JSX you can drop into your project or preview in Sandpack. It includes realistic interactive states — hover, active, loading, empty — not just a static mockup.
Yes. The generated JSX is fully editable. Sandpack gives you a live editor alongside the preview, so you can tweak copy, adjust colors, or add interactions without leaving the browser.
DemoDonkey generates plain React + Tailwind by default, which works with any setup. Custom design token support (your own color palette, fonts, radii) is on the Pro tier.
Typically 10–30 seconds depending on complexity. Claude generates the component in one pass — you see it appear in the Sandpack preview as soon as it's ready.
No — DemoDonkey works for any web UI: internal tools, developer dashboards, mobile apps mocked as React, CLI output prettified for a sales call. If it's a UI you'd want to demo, it works.
