U++ is a cross-platform rapid application development environment in C++. Can work with GCC, Clang, MinGW and Visual C++ and contains a full-featured debugger.
Fast development comes from smart and aggressive use of C++, not fancy code generators. In this regard, U++ competes with popular scripting languages while retaining the runtime characteristics of C/C++.
The development environment includes BLITZ build technology for up to 4x faster C++ rebuilds, visual designers for U++ libraries, Topic++ for documenting code and creating rich text resources for applications (such as help and code documentation), and Assist++, a powerful C++ code analyzer , which provides features such as code completion, navigation, and transformation.
