↓ Weaknesses

Limited to Python onlyhigh

pudb is specifically designed for debugging Python code and does not support other programming languages.

Text-based interface may be less intuitive than graphical debuggersmedium

The full-screen terminal interface, while powerful, can be less visually intuitive compared to GUI-based debuggers for some users.

Smaller community and slower development pacehigh

pudb has a smaller user base and fewer contributors compared to more mainstream debugging tools like PyCharm's debugger or Visual Studio Code's Python extension, leading to potentially slower feature updates and bug fixes.

Advanced features may require deep understanding of Python internalsmedium

To fully leverage advanced debugging capabilities such as variable inspection and step-by-step execution, users need a solid grasp of Python's internal workings and debugging concepts.
