FastAPI vs Flask

The Python framework that makes you feel like a genius, until you realize you're just using type hints meets the microframework that's actually micro. Here's our take.

FastAPI

Nice Pick

The Python framework that makes you feel like a genius, until you realize you're just using type hints.

Pros

• Automatic OpenAPI documentation generation
• Built-in data validation with Pydantic
• Async support out of the box

Cons

• Dependency injection can get messy in large projects
• Steeper learning curve for beginners compared to Flask

Flask

The microframework that's actually micro. Perfect for when you want to build a web app without the bloat of Django.

Pros

• Lightweight and minimalistic, making it easy to get started quickly
• Flexible and unopinionated, allowing you to choose your own tools and libraries
• Great for small to medium-sized projects or APIs
• Extensive documentation and a large, supportive community

Cons

• Lacks built-in features like an ORM or admin panel, requiring more manual setup
• Can become unwieldy for large, complex applications without careful architecture

The Verdict

Use FastAPI if: You want automatic openapi documentation generation and can live with dependency injection can get messy in large projects.

Use Flask if: You prioritize lightweight and minimalistic, making it easy to get started quickly over what FastAPI offers.

The Bottom Line

FastAPI wins

The Python framework that makes you feel like a genius, until you realize you're just using type hints.
