A2UI - A streaming protocol for user interfaces driven by agents.

A2UI is an innovative protocol designed for agent-driven interfaces, enabling AI agents to create rich, interactive user interfaces that work seamlessly across web, mobile, and desktop platforms. It allows agents to send declarative component descriptions instead of executing arbitrary code, ensuring security and ease of use. Currently in public preview, A2UI is actively developed by Google and the open-source community, with a focus on collaboration and feedback.

1. Declarative Data Format

   A2UI uses a declarative data format that prevents executable code, ensuring that agents can only utilize pre-approved components, thus mitigating UI injection attacks.

2. LLM-Friendly Structure

   The flat, streaming JSON structure is designed for easy generation, allowing large language models (LLMs) to build UIs incrementally without needing perfect JSON in one go.

3. Framework-Agnostic

   A2UI responses are compatible across various frameworks, enabling the same UI to be rendered on Angular, Flutter, React, or native mobile applications with custom styling.

4. Progressive Rendering

   Users can see the interface being built in real-time as UI updates are streamed, enhancing the interactive experience.

5. Core Concepts and Developer Guides

   A2UI provides comprehensive documentation on core concepts, data binding, and integration guides for developers looking to implement A2UI renderers or build agents.

6. Custom Components

   The protocol supports interactive charts and maps, allowing agents to respond with custom components tailored to user queries.
