FastAPI vs Flask: which is better for APIs?

The question is about FastAPI .

Answer:

FastAPI is modern and async, delivering higher performance with auto-generated OpenAPI documentation and strong typing via Pydantic, making API development faster and safer. Flask is lightweight and has a huge ecosystem, making it great for prototypes or when flexibility is key. For fast, stable, and well-documented modern APIs, choose FastAPI. Use Flask for small apps or when deep custom setups are required.
