x64dbg is an open-source user-mode binary debugger for Windows supporting both 32-bit and 64-bit executables. It is optimized for reverse engineering and malware analysis, featuring a disassembler, scripting, and an extensible plugin system.
Use cases
- debug a Windows executable without source code
- analyze malware dynamically
- reverse engineer a 32-bit or 64-bit binary
- set conditional breakpoints and trace execution
- patch and disassemble an EXE or DLL
- solve CTF reverse engineering challenges
- develop exploits by inspecting memory and registers
When to choose
- you need a free, open-source alternative to OllyDbg or commercial debuggers on Windows
- you are doing malware analysis or reverse engineering of Windows binaries
- you want a scriptable, plugin-extensible debugger with a familiar GUI
When to avoid
- you need to debug Linux or macOS binaries
- you only need static analysis without dynamic debugging
- you need kernel-mode or driver debugging
