Ghidra (pronounced Gee-druh;[3] /ˈɡdrə/[4]) is a free and open source reverse engineering tool developed by the National Security Agency (NSA) of the United States. The binaries were released at RSA Conference in March 2019; the sources were published one month later on GitHub.[5] Ghidra is seen by many security researchers as a competitor to IDA Pro.[6] The software is written in Java using the Swing framework for the GUI. The decompiler component is written in C++. Ghidra plugins can be developed in Java or in Python (provided via Jython).[7]


Ghidra's existence was originally revealed to the public via WikiLeaks in March 2017,[8] but the software itself remained unavailable until its declassification and official release two years later.[5]

In June 2019, Coreboot began to use Ghidra for its reverse engineering efforts on firmware-specific problems following the open source release of the Ghidra software suite.[9]

Ghidra can be used as a debugger since Ghidra 10.0. Ghidra's debugger supports debugging user-mode Windows programs via WinDbg, and Linux programs via GDB.[10]
