Pydantic 2 offers type-safe agents, evals and tracing for Python services, Astral's Ruff and ty 6 provide fast linting and type checking, SQLAlchemy 7 is the Python SQL toolkit and ORM, and suss 8 performs behavioral analysis of Python code against its boundaries such as routes and tables. Which platform or framework the backe

A question back: Which framework or platform does the Python backend use (for example FastAPI, Django, or an AI agent service)?
