JD-GUI vs Edb-Debugger: Which Kali Linux Tools tool is Best in 2025?

JD-GUI is an open-source, standalone graphical Java decompiler, available on Kali Linux at /usr/bin/jd-gui, designed for reverse-engineering compiled Java applications by extracting readable source code from .class or .jar files. Developed by Emmanuel Dupuy and packaged for Kali by Sophie Brun, JD-GUI provides a user-friendly GUI to browse class hierarchies, view decompiled Java code, and save sources as .java files. Ideal for cybersecurity researchers, Android developers, and ethical hackers, it supports malware analysis, code auditing, and vulnerability research. Often paired with tools like Dex2Jar, JD-GUI simplifies Java bytecode analysis.

Edb-Debugger, pre-installed on Kali Linux at /usr/bin/edb, is an open-source, cross-platform graphical debugger for x86 and x86-64 binaries, inspired by OllyDbg but designed for Linux, with ongoing ports to FreeBSD, OpenBSD, macOS, and Windows. Developed by Evan Teran, EDB (Evan’s Debugger) leverages the ptrace API and Capstone disassembly library to provide a modular, extensible platform for reverse engineering and malware analysis. With its intuitive GUI, plugin-based debugging core, and support for conditional breakpoints, it’s a vital tool for cybersecurity researchers, ethical hackers, and forensic analysts.
