FastAPI is a modern, fast (high-performance), web framework for building APIs
with Python 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.
* estimation based on tests on an internal development team, building
production applications.
