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 it works on multiple Operating Systems and Hardware Architectures with performance without needing to write platform-specific code.

It possesses an Integrated Development Environment called TheIDE[3] that is designed to handle all library features.


Some key features includes

  • An IDE with a GUI designer
  • Uses heavily RAII and auto pointers-like mechanisms to avoid manual memory management and could 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]
