U++, formally known as Ultimate++ - is a C++ RAD framework that aims to reduce the code complexity of typical desktop applications by including all necessary toolkits into a single C++ framework. Programs created with U++ work on multiple Operating Systems and Hardware Architectures with performance without needing to write platform-specific code.

It has its own Integrated Development Environment called TheIDE^[3] that is designed to handle all library features and plugins.

Some key features includes

• An IDE with a GUI designer
• Extensive use of RAII and auto pointers-like mechanisms to avoid manual memory management and limit the use of pointers in the code ^[4]
• Can emulate^[5] native widgets look and feel. On X11 systems, Ultimate++ supports GTK+ widgets look and feel.
• The standard distribution comes with U++ sources included.
• Uses NTL as a template system instead of STL.
• Supports databases, with libraries to connect with various database systems.
• Designed for high-performance application use cases with a low memory footprint and efficient use of system resources.
• Retains backward compatibility, allowing developers to upgrade to new versions of the framework without issues.
• Provides support for Unicode to make applications in multiple languages.
• Document editor,^[6] Debugger, auto completion^[7] and Icon Designer^[8] for making tool icons with less effort.
• Possible to work with Android NDK and SDK^[9]
• Web development and other features ^[10]

• macOS
• GNU / Linux
