Google ships A2UI 1.0, first stable release of its framework-agnostic Generative UI protocol
sull · x · 2026-11-13
Google has released A2UI 1.0, the first stable version of its framework-agnostic open standard for Generative UI, with CopilotKit announcing day-one support after working with Google's A2UI team since the initial release.
Key points:
- A2UI natively travels over AG-UI (Agent-User Interaction Protocol), so any AG-UI agent can adopt A2UI 1.0 with no custom integration
- The goal is to replace walls of text with structured UI; the teams argue Generative UI is now mature for real products
- With CopilotKit, developers can add OpenAI-style intelligent UI to their agentic apps in two lines of code, using their own components or a pre-built catalog
- Supports React, Angular, Flutter and Slack surfaces, and works with agent stacks including LangChain, ADK, Mastra and Claude Agents
