Tool Creation And Playground With Live Testing

via “playground and interactive testing with parameter override and output inspection”

Visual multi-agent and RAG builder — drag-and-drop flows with Python and LangChain components.

Unique: Provides an interactive playground UI that displays real-time execution traces with component-level input/output inspection and timing information. Supports both single-run testing and batch testing with multiple input sets, enabling rapid iteration without deployment.

vs others: More accessible than command-line testing because it's visual; more detailed than simple output inspection because it shows execution traces and component-level logs.
