FastAPI for backend APIs

A high-performance Python framework for building APIs based on standard type hints and OpenAPI.

FastAPI leverages modern Python features to deliver execution speeds comparable to Go and Node.js. By utilizing Pydantic for data validation and Starlette for web tooling, it automates the creation of interactive Swagger UI documentation and ensures type safety across the stack. Developers typically see a 200% to 300% increase in feature delivery speed while reducing human-induced errors by roughly 40% through its intuitive design and robust editor support.
