GNU Project Debugger is described as 'Or gdb, is a command-line, source-level debugger for programs that were written in C, C++, D, Objective-C, Fortran, Java, Pascal, assembly, Modula-2, or Ada and compiled for any of a number of different target architectures including x86, x86-64, IA-64' and is a Decompiler in the development category. There are more than 10 alternatives to GNU Project Debugger for a variety of platforms, including Windows, Linux, Mac, BSD and Web-based apps. The best GNU Project Debugger alternative is Ghidra, which is both free and Open Source. Other great apps like GNU Project Debugger are IDA, radare2, OllyDbg and Cutter.
Ghidra is a software reverse engineering (SRE) framework created and maintained by the National Security Agency Research Directorate. This framework includes a suite of full-featured, high-end software analysis tools that enable users to analyze compiled code on a variety of...
IDA delivers robust disassembly and decompilation, supporting diverse processors and file formats. Its high-quality pseudocode mirrors original source code, aiding analysis of multi-platform software. It features dynamic debugging, metadata control with Lumina, and effective code deobfuscation.
Radare project started as a forensics tool, a scriptable commandline hexadecimal editor able to open disk files, but later support for analyzing binaries, disassembling code, debugging programs, attaching to remote gdb servers, ...
OllyDbg is a 32-bit assembler level analysing debugger. Emphasis on binary code analysis makes it particularly useful in cases where source is unavailable.
Cutter goal is to be an advanced FREE and open-source reverse-engineering platform while keeping the user experience at mind. Cutter is created by reverse engineers for reverse engineers.
dnSpyEx is an unofficial continuation of the dnSpy project which is a debugger and .NET assembly editor. You can use it to edit and debug assemblies even if you don't have any source code available. Main features:
EDB (Evan's Debugger) is a Qt4 based binary mode debugger with the goal of having usability on par with OllyDbg. It uses a plugin architecture, so adding new features can be done with ease. The current release is for Linux, but future releases will target more platforms.
Hopper is a reverse engineering tool for OS X and Linux, that lets you disassemble, and decompile your 32/64bits Intel Mac, Linux, Windows and iOS executables!
