Users simply describe the app they want, and Gemini 3.1 Pro handles the technical implementation. Apps can be built directly in the browser and can include features such as payment processing, data storage, and messaging. According to Google, even multiplayer applications like real-time games are possible.

A new “Antigravity Agent” automatically detects when an app requires a database or authentication and sets both up via Firebase. External services such as payment providers or Google Maps can be integrated using custom API keys. The agent can also autonomously install web tools like Framer Motion or Shadcn when needed. In addition to React and Angular, support for Next.js has now been added.
