and FastAPI

FastAPI is a high-performance Python web framework designed for building production-ready APIs with automatic validation and documentation.

FastAPI leverages modern Python features like type hints and async/await to deliver performance on par with NodeJS and Go. Built on Starlette for routing and Pydantic for data validation, it eliminates boilerplate by generating interactive Swagger UI and ReDoc documentation automatically. Developers use it to build robust microservices and machine learning interfaces because it reduces human-induced errors by approximately 40 percent through strict schema enforcement. It is the standard choice for teams needing high-concurrency handling and rapid development cycles without sacrificing execution speed.
