Quick Gemini-powered prototypes, web or Android, for free in the browser; API costs arrive once deployed apps get real use.

Kenning's take

What it does

Build mode in Google AI Studio lets users describe an app in plain language and get a working full-stack web app or native Android app with a live preview. It runs on the Antigravity agent, which manages files across the project, installs npm packages and keeps secrets on the server side. Projects can be started from a prompt, remixed from a gallery or imported from GitHub.

  • Full-stack web apps with React and Node.js
  • Native Android apps in Kotlin and Jetpack Compose
  • Powered by the Antigravity agent
  • Import from GitHub or remix gallery apps
  • Server-side secrets and npm packages

Who it suits. People who want to prototype Gemini-powered apps quickly, with or without much coding.
