A2UI v0.9: The New Standard for Portable, Framework-Agnostic Generative UI- Google Developers Blog

This post introduces A2UI v0.9, a framework-agnostic standard for generative UI. It details the 'Basic' component set, a shared web-core library with official React renderer and support for other renderers (Flutter, Lit, Angular), and the A2UI Agent SDK. The SDK features optimized generation pipelines, caching, client-defined functions, client-to-server data syncing, improved error handling, modular schema, and simplified transports. The integration process for Python agents is outlined with a 5-step example. Advanced SDK features like version negotiation, dynamic catalogs, and resilient streaming are also discussed. Ecosystem updates from AG2, A2A, Vercel, and Oracle are mentioned, along with examples of its application in Personal Health Companion and Life Goal Simulator.
