Google AI Studio (Build mode)

Gemini prompt-to-app playground

Free tier + paidAI app buildersaistudio.google.com

What it is

Build mode turns a prompt into a full-stack app: a React frontend with a Node.js backend runtime for secure API calls and npm packages, or a Kotlin and Jetpack Compose Android project. Export as ZIP, sync to GitHub, or deploy straight to Cloud Run. Your Gemini key is injected server-side.

Why it earns a slot

Google's designated Firebase Studio replacement and the cheapest serious builder here — there is no credit meter, only Gemini API quota. Best when the app is itself Gemini-powered, since model access is native rather than bolted on.

Know before you commit

Prototype-grade polish next to Lovable or v0, and shared apps bill Gemini calls against your own quota. Free API tiers are rate-limited, and Google may use free-tier data to improve its products.
