Development Web Ui With Function Call Visualization And Execution Tracing

Google's agent framework — tool use, multi-agent orchestration, Google service integrations.

Unique: Provides FastAPI-based web UI for local agent development with visual function call tracing, execution flow visualization, and replay capabilities. Integrates with agent runtime via API endpoints for real-time monitoring.

vs others: More integrated than generic debugging tools — purpose-built for agent execution visualization with function call details and multi-agent hierarchy tracing, whereas generic debuggers lack agent-specific context
