What is FastAPI?
The official FastAPI website describes FastAPI as a modern and high-performance web framework for building APIs with Python 3.6+ based on standard Python type hints. FastAPI is very fast due to its out-of-the-box support of the async feature of Python 3.6+.
FastAPI was released in 2018, and it was created by Sebastián Ramírez. Ramírez was unhappy with existing frameworks like Flask and DRF, so he created his own framework using tools like Starlette and Pydantic. Now, many big tech companies like Uber, Netflix, and Microsoft are using FastAPI to build their apps.
