Google releases A2UI 1.0, a stable open protocol for agent-generated native UI
A2UI 1.0: Build delightful, fast, reliable, agentic experiences
Google released A2UI 1.0, the first stable version of its open protocol that lets AI agents answer with interactive screens rendered by each app's own native components. Version 1.0 adds bidirectional function calls, accessibility support and extension metadata, plus open-source renderers for React, Angular, Lit, Flutter, SwiftUI and Jetpack Compose (the Compose renderer is at 0.9.1 with 1.0 coming soon) and agent SDKs for Python, TypeScript and Dart. Atlassian is bringing A2UI to Jira, Alation renders its feeds with it in Claude, and ByteDance shipped a Lynx renderer in June 2026 that supports 0.9 today.
Google's stable A2UI 1.0 protocol lets agents return native interactive screens instead of text walls, with renderers for web, Android and iOS and early adopters including Atlassian and ByteDance.
