# RAD Debugger

> The RAD Debugger is Epic Games' native, multi-process graphical debugger for x64 programs. Windows is the main platform; Linux support is very early and there is no macOS support. The repo also holds the RAD Linker (an MSVC-compatible PE/COFF linker for very large projects) and the RDI debug-info format. The README says the debugger is in alpha. Prebuilt binaries are on the Releases page, or build with MSVC/Clang or GCC. MIT licence. It is a free tool and does not replace a paid product.
