Google ships A2UI 1.0: an open protocol for generative, native agent UIs

rseroter · x · 2026-11-13

Google released A2UI 1.0, the first stable open-source (Apache 2.0) protocol for generative UI: agents describe what to show and apps render it with native components — forms, charts, pickers — at native speed with sensitive data kept server-side. Renderer SDKs cover Web/Android/iOS (React, Angular, Lit, Compose, SwiftUI, Flutter) plus agent SDKs for Python/TypeScript/Dart. Atlassian, Alation, Bloomberg, and ByteDance are already building with it.
