JD-GUI vs Sublist3r vs WPScan: Which Metasploit GUI 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.

Sublist3r is a powerful, open-source Python tool designed for subdomain enumeration using Open-Source Intelligence (OSINT). Integrated into Kali Linux, it assists ethical hackers, penetration testers, and bug bounty hunters in discovering subdomains associated with a target domain. By leveraging search engines like Bing, Yahoo, Google, Baidu, and Ask, as well as services such as Netcraft, VirusTotal, ThreatCrowd, DNSdumpster, and ReverseDNS, Sublist3r compiles comprehensive subdomain lists. It also integrates Subbrute for brute-force enumeration, enhancing its ability to uncover hidden subdomains.

WPScan is a powerful, open-source WordPress security scanner designed to identify vulnerabilities in WordPress-powered websites. Pre-installed on Kali Linux, this command-line tool helps ethical hackers, penetration testers, and website administrators detect security flaws in WordPress core, plugins, themes, and configurations. Written in Ruby, WPScan leverages a comprehensive vulnerability database from wpvulndb.com to provide real-time insights into potential risks. With features like user enumeration, brute-force attack simulation, and detailed reporting, WPScan is a critical tool for securing WordPress sites, which power over 40% of the internet. It supports both passive and aggressive scanning modes, ensuring flexibility for various testing scenarios.
