Introducing A2UI: An open project for agent-driven interfaces- Google Developers Blog

What this post added

Introduces A2UI (Agent-to-UI), an open-source project and format for agents to generate and update user interfaces. A2UI is a declarative data format, not executable code, designed for security, incremental updates, and framework-agnostic rendering. It allows agents to compose UIs from a catalog of components, enabling richer and more efficient user interactions compared to text-only interfaces. A2UI aims to solve the challenge of rendering UI from remote, untrusted agents by providing a safe, data-like transmission of UI specifications that clients can render natively, retaining control over styling and security.
