This tool analyzes a React frontend and its backend API endpoints by probing them live with real authentication. It maps frontend API calls to backend routes, detects failures, and classifies root causes with evidence and confidence levels. Use it to quickly identify why pages show no data or broken states, especially in apps using FastAPI, Express, Next.js, tRPC, or GraphQL with OpenAPI specs. It exposes diagnostic queries over MCP for AI-assisted debugging.
