Python Web Frameworks: FastAPI, Django, and Flask
Choosing the right Python web framework shapes your entire project. FastAPI brings async-first design and automatic API docs. Django offers a complete ecosystem with ORM, admin, and auth out of the box. Flask gives you minimal structure and maximum flexibility. Each has clear strengths depending on your project requirements.
This collection compares the frameworks and covers the practical details of building with each one.
