Qt Pros & Cons

Pros of Qt:

Cross-Platform Compatibility: Qt supports the WOCA (Write Once, Compile Anywhere) principle, allowing applications to run on multiple operating systems, including desktop, mobile, and embedded systems.
Feature-Rich Framework: Qt provides a comprehensive set of tools and libraries for GUI development, multimedia, database management, networking, and more.
Open-Source and Commercial Options: Qt offers both open-source and commercial licenses, providing flexibility for different development needs.
Native-Looking GUIs: Qt allows for the creation of native-looking GUIs across various platforms, making it a reasonable choice for businesses.
Community Support: Qt has a dedicated community and excellent documentation, which can be beneficial for developers.

Cons of Qt:

Steep Learning Curve: Qt requires a good understanding of C++, which can be challenging for developers not familiar with the language.
Complexity: The use of complex templates and manual memory management in C++ can lead to performance issues and codebase maintenance challenges.
Debugging Issues: Qt Creator has been criticized for its debugging capabilities, which can be slower and less intuitive compared to Visual Studio.
Cost for Commercial Use: The commercial license for Qt can be expensive, which may deter some developers, especially startups.
Limited Web Support: Historically, Qt has been less popular for web development due to its late adoption of WebGL and WASM, although this is improving.
