FastAPI framework, high performance, easy to learn, fast to code, ready for production --- **Documentation**: [https://fastapi.tiangolo.com](https://fastapi.tiangolo.com) **Source Code**: [https://github.com/fastapi/fastapi](https://github.com/fastapi/fastapi) --- 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](#performance). * **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](https://github.com/OAI/OpenAPI-Specification) (previously known as Swagger) and [JSON Schema](https://json-schema.org/). * estimation based on tests conducted by an internal development team, building production applications. ## Sponsors ### Keystone Sponsor ### Gold Sponsors ### Silver Sponsors [Other sponsors](https://fastapi.tiangolo.com/fastapi-people/#sponsors) ## Opinions "_[...] I'm using **FastAPI** a ton these days.
