I'm a junior CS student and solo founder, and today I launched DemoDonkey on Product Hunt.

What it does: You describe your product, pick a theme, and DemoDonkey uses Claude to generate a polished interactive demo preview in under 60 seconds. No real app needed, no real data, no setup. Just describe your product and screen record the result.

Why I built it: I was launching another project (Monkey Mentor, an AI study tool) and spent three hours trying to get a clean demo recording. Staging was broken, test data looked fake, kept clicking the wrong thing. So I built the tool I wished existed.

The stack: Next.js, Anthropic Claude API, Sandpack for live preview, PostgreSQL, Upstash, Vercel. Built it in about 4 weeks alongside university and a hospital job.

Where it's at: Free tier live, waitlist for Pro. Getting way more traffic than I expected from the Product Hunt launch which is both exciting and terrifying given I'm the only person running this.

What I learned building it:

• Prompt engineering for consistent code generation is genuinely hard — took most of the 4 weeks
• Shipping fast and validating before building everything is real — I almost built auth and billing before anyone had used it
• Building in public actually works. Every time I shared progress I got useful feedback

Would love any feedback on the product or the launch. And if you've struggled with demo recordings before, give it a try — it's free and takes 60 seconds.

Happy to answer any questions about the build!

I found that creating a demo for my SaaS was difficult. I wanted to create one to show users how my product worked but I didn’t want to spend too much time and effort actually implementing the features.

I thought the workflow could be simplified so I’m working on creating an automated demo generator.

I’m curious what your current workflow for making demos is, any feedback would be helpful!

Recently I’ve been developing a lot of SaaS products and came to a conclusion. I wanted to create an MVP for my product but didn’t want to spend too much effort or time on building it.

Imagine wasting days or weeks building a working demo then finding out no one wants it.

Thats why I built DemoDonkey. Simply fill a form describing what your product does and it’ll generate an interactive demo for you. You can use it to record a demo to show off your product, or download the code to embed it into your landing page.

I’m looking for some feedback, there’s a free demo of how it works… ironic haha. Anyways, no sign up needed, I’m simply looking for testers!
