Use Django for full-stack web applications that need user accounts, an admin interface for content management, forms with validation, or an ORM for complex data relationships. It's the right choice when you want a complete, production-ready framework with a well-trodden path for common features.
Use Flask for small-to-medium web apps and APIs where you want to control the stack, for prototypes where you need something running fast, or when teaching web development concepts without the complexity of Django.
Django is heavy for pure REST APIs — the ORM, templates, and admin panel add weight you don't use. FastAPI is a better starting point for API-only projects. Django's synchronous-by-default nature (though async support has improved) can also be a constraint for highly concurrent applications.
Flask becomes painful as an app grows — you end up assembling Django yourself from extensions. For async APIs, FastAPI is a better starting point. For anything needing built-in auth, admin, or ORM, Django pays off faster.
