Which framework — Flask or Django — uses more system resources during operation?

Django generally uses more system resources compared to Flask. This is because Django is a full-featured framework with many built-in components (ORM, authentication system, admin panel, etc.) that load and run even in simple applications.

Flask, on the other hand, is a micro-framework that provides a minimal set of features and allows adding only necessary extensions, making it more lightweight and less resource-intensive.

Therefore, if minimizing resource usage is important, Flask would be preferable, especially for small or simple applications.
