How to Build a Marketplace App With AI

Build a working marketplace for iOS, Android, Web and macOS in minutes — no setup, no SDKs, no boilerplate. Just describe what you want.

What you will build

A real native marketplace for connecting buyers and sellers in a niche, with the following features:

Step-by-step

Step 1: Open Luna at luna-heaven.com

No signup wall — you can start in seconds. Luna will greet you. Tell her what you want to build.

Step 2: Describe your marketplace in plain English

Tell Luna: "I want a marketplace for connecting buyers and sellers in a niche. The core features I need are listings, search, payments." Luna will ask clarifying questions.

Step 3: Watch Heaven Code Studio generate Flutter code

Luna writes real, owned Flutter code — not pseudocode — across screens, services, models and theming, with deterministic spec fallback so the preview always renders.

Step 4: Preview your app live in the browser

Heaven Code Studio renders your app live. Tap, scroll, navigate — give Luna feedback by voice or text and she iterates.

Step 5: Deploy to iOS, Android, Web and macOS

Export the Flutter project, run flutter build, and deploy. Or use Luna's guided deploy assistance to ship to the App Store / Play Store / Firebase Hosting.

Frequently asked

Can Luna really generate a working marketplace?

Yes. Heaven Code Studio writes real Flutter code that runs on iOS, Android, Web and macOS. The output is yours — exportable as a normal Flutter project — and Luna will iterate with you across sessions thanks to persistent project memory.

Do I need to know how to code?

No. You describe what you want; Luna writes the code. If you do know how to code, Luna becomes a faster pair — you can edit any file directly and she will continue from your edits.

Is this free?

Not all of it. Chat, voice and persistent memory are free forever. Heaven Code Studio, which builds the marketplace, is a Developer Program feature at $9.99 / month, as are Heaven Gaming, Luna CEO and the Developer API.

Where does my code live?

Your project lives in your Memory Pod (encrypted, cross-device). When you are ready, you export a normal Flutter project to your own GitHub / hard drive.

Can I ship to the App Store?

Yes. The output is a standard Flutter project — you can sign and submit it through Xcode like any other app. Luna can also guide you through the App Store / Play Store submission process.
