x64dbg is an open-source debugger for Windows that allows developers to inspect and analyze running processes at a low level, supporting both 32-bit and 64-bit applications. Developers use it primarily for reverse engineering, malware analysis, and security research by stepping through code execution, examining memory, and understanding program behavior without access to source code. It includes built-in disassembly capabilities and is commonly used in exploit development, CTF competitions, and offensive security work where understanding binary execution is critical.
