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%. * (note1)

* Fewer bugs: Reduce about 40% of human (developer) induced errors. (note1)

* 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.
