How to Create a Product Demo Without a Live App

Recording a product demo sounds simple. Open your app, hit record, click through the features. Done.

Except it never works that way.

Your staging environment is down. The test data looks fake. You accidentally navigate to a broken page. The loading spinner takes 8 seconds. You start over. Three hours later you have a passable video that you're not proud of.

There's a better way.

The problem with recording your real app

Real apps have real problems:

• Environment fragility — staging breaks, production data is sensitive, local setup differs per machine
• Imperfect data — real databases have messy, incomplete, or confidential records
• Timing issues — real network requests, loading states, and animations don't always behave on camera
• One-take pressure — one wrong click means starting over

What you actually want is a demo that looks real but runs perfectly every time.

The solution: generate an interactive mock

Instead of recording your real app, generate an interactive mockup that simulates your product's UI with realistic fake data. It looks identical to your real app on camera, but runs flawlessly every time.

This is exactly what DemoDonkey does.

How it works

1. Describe your product — tell DemoDonkey what your product does, who uses it, and what the key screens are
2. Generate the demo — Claude generates a complete interactive React component with browser chrome, animated panels, realistic mock data, and a branded ending screen
3. Preview and refine — the demo renders live in your browser. Use the refinement prompt to tweak anything that doesn't look right
4. Screen record it — open your screen recorder, hit play, and the demo runs itself

The whole process takes under 60 seconds.

What makes a good product demo

Whether you use DemoDonkey or record your real app, a great demo has these qualities:

• Clean data — numbers that look realistic, names that sound real, no obviously fake content
• Smooth transitions — no loading spinners, no jarring page changes
• Focused flow — shows the 3-4 key features, no more
• Branded ending — ends with your product name and a clear CTA

DemoDonkey generates all of these automatically based on your product description.
