Features
Describe your product and get a pixel-perfect React component from an AI-generated demo workflow — not a screenshot, an actual interactive UI with state and hover effects.
Sandpack renders an interactive demo preview 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. This product demo generator output fits any screen recording workflow.
Not happy with a section? Type what you want changed and DemoDonkey rewrites it instantly — no re-generating from scratch.
