Google has launched A2UI, an open-source project that allows AI agents to create interactive user interfaces for applications. Instead of sending executable code, agents describe UI components in a structured format, which host apps then render natively. This approach enhances security and design consistency across platforms.

A2UI is a protocol that allows AI agents to create interactive user interfaces without executing code, ensuring security by using only approved components. The system supports various frameworks and streams UI updates in real-time for a seamless user experience. It's currently in public preview and welcomes community contributions.
