Google A2UI Spring 2026 Update: OpenClaw Integration and ADK Python Expansion at v0.8 Public Preview
Google's A2UI (Agent-to-User Interface) declarative standard shipped a Spring 2026 update adding OpenClaw integration and expanded ADK Python support, now at v0.8 Public Preview under Apache 2.0. A2UI lets agents generate structured UI responses (using client-trusted component catalogs, not arbitrary code) that render across Angular, Flutter, React, and native mobile from a single agent response. The OpenClaw integration is the key signal: connecting the largest agent ecosystem (210K+ stars) to Google's UI standard could establish A2UI as the cross-platform agent UI layer before competing specs gain traction.
