FastAPI

FastAPI is a modern, fast (high-performance) web framework for building APIs with Python 3.8+ based on standard Python type hints. It leverages Starlette for the web parts and Pydantic for data validation and serialization. It features automatic OpenAPI documentation (Swagger UI, ReDoc). The current version is 0.136.0, and it maintains a frequent release cadence, often with minor updates several times a month.
