Known weaknesses

Each one links to the public issue, changelog or docs page it came from, where we have one.

1. 01

   Steep learning curve for non-Python developers

   The Django Debug Toolbar is tightly integrated with Python and Django-specific patterns, which can be challenging for developers unfamiliar with these ecosystems.

2. 02

   Limited support for modern web frameworks

   While Django Debug Toolbar works well with Django, it may not integrate seamlessly with newer or more modern Python web frameworks like FastAPI or Flask without significant configuration.

3. 03

   Performance overhead in production environments

   Enabling the toolbar in a production environment can introduce performance overhead and security risks, as it is primarily designed for development use.

4. 04

   Documentation lacks depth on advanced configurations

   The official documentation provides basic setup instructions but falls short when it comes to detailed guidance on customizing or extending the toolbar's functionality.
