FastAPI is a modern, fast (high-performance), web framework for building APIs with Python 3.6+ based on standard Python type hints.
FastAPI is based on Pydantic and type hints to validate data, serialize, deserialize data, and automatically auto-generate openAPI documents.
This is free and open source software.
Features include:
- 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 for API creation, including declarations of path operations, parameters, body requests, security, etc.
- Automatic data model documentation with JSON Schema (as OpenAPI itself is based on JSON Schema).
- Designed around these standards, after a meticulous study. Instead of an afterthought layer on top.
- This also allows using automatic client code generation in many languages.
- Fully supports asynchronous programming and can run with Uvicorn and Gunicorn.
