Choose where your app will live
Three routes lead to the same installable app. Pick one, then continue to Part 5.
| Route | Good fit when | Limits to know | Updating later |
|---|---|---|---|
| Publish from AI StudioCloud Run Starter Tier | You want the fastest path to a live HTTPS URL, with no GitHub or host account. | First two apps only, one Cloud Run region, and not available if you've ever set up Google Cloud billing. | Publish again from AI Studio. |
| VercelPart 4 | You want automatic redeploys on every GitHub push. | The free Hobby plan is for non-commercial use only. | Automatic after each GitHub push. |
| ReplitPart 4B | You may charge for your app, or want everything in one dashboard. | The key is baked into a static build, so restrict it in Google AI Studio. | Pull the changes and click Deploy again. |
Before you begin
- Stable internet connection
- Chrome, Firefox, Safari, or Edge
- Android phone (optional)
- 45–60 mins of focused time
- Basic instruction-following ability
- No child accounts on any service

Jump to any section
The guide is split into focused pages — read in order for the full walkthrough, or jump straight to what you need.
- Part 1Steps 1–3Account SetupCreate your Gmail, GitHub, and Vercel accounts in the right order so everything links together cleanly.
- Part 2Steps 4–6Build in AI StudioDescribe your app idea in plain English and let Gemini's Build mode generate, preview, and iterate on it for you.
- Part 3Steps 7–11GitHub BridgeConfigure the two files that make your app installable, then export it to a GitHub repository.
- Part 4Steps 12–16Deploy to VercelImport your repo, wire up environment variables correctly, and go live with a free, HTTPS-secured URL.
- Part 4BSteps R1–R5Deploy to ReplitAn alternative to Part 4 with no non-commercial-use restriction — plus quick notes on Netlify and Cloudflare Pages.
- Part 5Steps 17–20Install on AndroidTurn your live URL into a home-screen app using Chrome's PWA install flow — no Play Store needed.
- Part 6SOPUpdate WorkflowThe exact sequence to follow every time you change your app, so an AI Studio re-export never breaks your live site.
