What you can build

Build with A2A

The user-facing primitives every A2A integration ships with — pick the one that fits your product and drop the code in.

Declarative UI (A2UI)

Render your agent's state, progress, outputs, and tool calls with custom UI components in real-time. Bridges the gap between AI agents and user interfaces.
