Open-source alternatives to ObjectDebugger

radare2 is a reverse engineering framework and binary analysis toolset. It functions as a multi-architecture disassembler, low-level binary debugger, and hexadecimal editor for inspecting executable structures and interpreting machine code when original source files are unavailable. The framework provides capabilities for decompiling machine instructions, performing symbolic analysis, and diffing binary files to identify structural changes across versions. It also includes a digital forensic analyzer and disk analyzer for browsing filesystem formats in userland. The toolset supports binary p

HyperDbg is a hardware-assisted kernel-mode debugging platform that leverages virtualization to monitor and control system execution. By utilizing hypervisor-level primitives, it enables deep system analysis and instrumentation without relying on standard operating system debugging interfaces. The framework provides a comprehensive environment for inspecting both kernel and user-mode processes, allowing for granular control over execution flow and system state. The project distinguishes itself through a transparent debugging layer designed to remain invisible to the target environment. It emp

w64devkit is a portable MinGW-w64 C/C++ development kit and a self-contained GCC toolchain for Windows. It provides a native build environment for compiling C, C++, and Fortran source code into x86 and x64 executable binaries without requiring system-wide installation or modifications to the host registry and environment variables. The toolchain is distributed as a self-contained suite of compilers, linkers, and assemblers that runs from any directory. It includes a specialized shell-based environment wrapper to automatically configure the path to its binaries and utilizes static linking to e
