Fastapi

FastAPI framework, high performance, easy to learn, fast to code, ready for production

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.

Pydantic

Pydantic is the most widely used data validation library for Python.

Fast and extensible, Pydantic plays nicely with your linters/IDE/brain. Define how data should be in pure, canonical Python 3.9+; validate it with Pydantic.
