A2UI is Google's take — declarative JSON, tool-calling based, predefined component catalog. Clean and safe but constrained.
My approach is the opposite bet: full code execution instead of tool calls. The agent can build any React UI from scratch with the full power of code — including client-server data flow, callbacks, streaming data.
