• Complexity: Can be more complex to use compared to simpler frameworks.
• Less Modern: Not as up-to-date as some newer frameworks.

Use Cases:

• Applications requiring a native look across multiple platforms.
• Desktop applications with complex user interfaces.
• Tools and utilities that need to blend with the OS environment.

5. PySide

PySide (also known as Qt for Python) provides Python bindings for the Qt application framework, similar to PyQt. It is officially supported by the Qt Company and offers an alternative to PyQt with a more permissive licensing model.

Key Features:

• Qt Integration: Leverages the powerful Qt framework.
• Free for All Uses: LGPL license allows for use in open-source and commercial projects.
• Cross-Platform: Compatible with multiple operating systems.

Advantages:

• Open License: More flexible licensing compared to PyQt.
• Rich Features: Access to advanced Qt features and widgets.
• Active Development: Regular updates and support from the Qt Company.

Limitations:

• Documentation: While comprehensive, it may not be as extensive as PyQt’s.
• Learning Curve: Similar to PyQt, it may have a steeper learning curve.

Use Cases:

• Professional applications with advanced requirements.
• Projects needing a permissive licensing model.
• Cross-platform software with complex UIs.

6. Dear PyGui

Dear PyGui is a relatively new framework for Python that focuses on creating fast, interactive UIs. It is designed for ease of use and high performance, making it suitable for applications that require real-time interaction.

Key Features:

• Real-Time Rendering: Supports high-performance, real-time graphics.
• Ease of Use: Simple API for quick development.
• Custom Widgets: Allows creation of custom UI elements.

Advantages:
