6 mobile templates

Build mobile apps with AI

Build an Android and iPhone app by describing it. Expo gives you React Native with one codebase for Android, iOS and the web; Capacitor wraps a Vite web app as a native app. Builds run on GitHub Actions on your own account, and the store listings come ready to upload.

Expo for native apps, Capacitor for web-first apps — and any web app you build here can be wrapped too
An installable Android APK and an iPhone build from the same project
Google Play and App Store listings written for you, ready to upload

How it works

  1. 1Pick a mobile starter below, or start from any web app
  2. 2Describe the app; preview it in iPhone and Pixel frames, or scan the QR code to open it on your phone
  3. 3Open Build app → Android / iOS in the builder
  4. 4GitHub Actions builds it on your account: an Android APK, and an iPhone build for testing
  5. 5Add your keystore and Apple certificate for signed store builds — and an App Store Connect key to upload to TestFlight

Every mobile project gets

  • A cloud sandbox with a live preview of the running app
  • A real terminal with 15 coding CLIs — Claude Code, Codex, Cursor CLI, Gemini CLI and more
  • AI on your own keys from 24 providers, billed by the provider at cost
  • Its own GitHub repository from the first push

Where it can go

Builds run on GitHub Actions on your account, so they cost nothing here, and downloads are private for 14 days. Android builds can run on a real emulator in your Actions with screenshots and a short video. Signed release builds use your own Android keystore and Apple certificate, and an App Store Connect API key uploads iPhone builds to TestFlight.

Questions

Can I build a mobile app with AI?

Yes. Pick one of 6 mobile templates — Android and iPhone apps with Expo and Capacitor — and describe what you want. The builder writes the code in a cloud sandbox with a live preview and a real terminal, using your own AI provider key.

How do I get the app onto phones and into the stores?

Builds run on GitHub Actions on your account, so they cost nothing here, and downloads are private for 14 days. Android builds can run on a real emulator in your Actions with screenshots and a short video. Signed release builds use your own Android keystore and Apple certificate, and an App Store Connect API key uploads iPhone builds to TestFlight.

What happens when I press Start?

You sign up — or, if you are already signed in, go straight on — and the New Web App dialog opens with that template picked. Set the name, stack, design, model and MCP tools there, then press Create.

Do I own the code?

Yes. The project is pushed to your own GitHub repository, and you can open a terminal on it at any point.
