A2UI – A secure protocol for AI-generated interactive UIs

Summary: A2UI is an open protocol by Google that enables AI agents to generate rich, interactive user interfaces using declarative JSON instead of executing code. It supports native rendering across Flutter, web, and mobile platforms, ensuring security and framework independence.

What it does

A2UI allows agents to send UI components as JSON for clients to render natively, avoiding risky code execution. It integrates with backend protocols to create dynamic, agent-driven interfaces.

Who it's for

Developers building AI-powered applications requiring secure, cross-platform UI generation and rendering.

Why it matters

It solves the challenge of safely transmitting UI components across trust boundaries without compromising security or flexibility.
