A2UI is Google's open-source framework that lets AI agents generate rich, interactive UIs using declarative JSON instead of executable code. Agents describe UI intent, clients render with native components (Flutter, React, SwiftUI). LLM-friendly format enables incremental updates and progressive rendering while maintaining security through a trusted component catalog.
