The Ultimate Face-off: Flask vs. FastAPI

Here is a summary of the text in 1 paragraph: Flask and FastAPI are two popular Python microframeworks used for building APIs and web applications. While both are stripped-down frameworks with faster development time and flexibility, they differ in their reliability, testing, and documentation support. Flask has been battle-tested and widely used, but is slightly less reliable than FastAPI, which is a newer framework known for its speed and built-in support like Pydantic and SwaggerUI. Both frameworks have similar installation processes, but FastAPI requires Uvicorn for faster performance. With FastAPI's automatic documentation, data validation, and asynchronous server capabilities, it offers advantages in development time, performance, and bug reduction. Ultimately, the choice between Flask and FastAPI depends on individual project needs, with Flask suitable for battle-tested frameworks, prototyping, and web application development, while FastAPI is ideal for speed, API building from scratch, and reducing errors.
