Libcsdbg is an open-source debugging library and application for C and C++ development. It is designed to provide a better debugging experience than the standard debugging tools available on most platforms. It is focused on providing a highly optimized debugging experience, including features such as source code-level debugging, advanced breakpoints and watchpoints, support for multiple threads, and advanced memory and stack management. It can be used to debug both local and remote applications, and can be integrated with popular IDEs such as Visual Studio, Eclipse, and Code::Blocks.
