Active development

x64dbg is under constant active development.


We provide both the executable and the source. Feel free to contribute.


Write plugins in C++, change colors and tweak your preferences.

x64/x32 support

x64dbg can debug both x64 and x32 applications. There is only one interface.

Built on open-source libraries

x64dbg uses Qt, TitanEngine, capstone, Yara, Scylla, Jansson, lz4 and XEDParse.

Simple, powerful development

x64dbg uses C++ and Qt4 to quickly add new features.


x64dbg has an integrated, debuggable, ASM-like scripting language.


x64dbg has many features thought of or implemented by the reversing community.


Write plugins to add script commands or to integrate your tools.
