FastAPI is a modern, fast (high-performance), web framework for building APIs with Python 3.6+ based on standard Python type hints.
The key features are:
- Fast : Very high performance, on par with NodeJS and Go (thanks to Starlette and Pydantic). One of the fastest Python frameworks available.
- Fast to code : Increase the speed to develop features by about 200% to 300%. *
- Fewer bugs : Reduce about 40% of human (developer) induced errors. *
- Intuitive : Great editor support. Completion everywhere. Less time debugging.
- Easy : Designed to be easy to use and learn. Less time reading docs.
- Short : Minimize code duplication. Multiple features from each parameter declaration. Fewer bugs.
- Robust : Get production-ready code. With automatic interactive documentation.
- Standards-based : Based on (and fully compatible with) the open standards for APIs: OpenAPI (previously known as Swagger) and JSON Schema.
