FastAPI
FastAPI framework, high performance, easy to learn, fast to code, ready for production
FastAPI is a modern, fast (high-performance), web framework for building APIs with Python 3.7+ based on standard Python type hints. The key feature is that it's fast to code, reduces bugs, and is easy to use, yet it provides high performance, on par with NodeJS and Go (thanks to Starlette and Pydantic). It's one of the fastest Python frameworks available.
