Skipfish vs Bully vs Nishang: Which Pricing tool is Best in 2025?

Skipfish is an open-source web application security reconnaissance tool pre-installed in Kali Linux, designed for automated penetration testing and vulnerability scanning. Developed by Google and maintained on GitHub, it performs recursive crawls and dictionary-based probes to create an interactive sitemap of a target website, annotating it with results from non-disruptive security checks. With a lightweight 559 KB footprint, Skipfish achieves high performance (500+ requests/second on internet targets, 2000+ on LAN), detecting vulnerabilities like XSS, SQL injection, and directory traversal in CMS platforms like WordPress and Joomla. Its 15+ modules, including metagoofil and wananga, support comprehensive scans, while features like form authentication, custom headers, and heuristic wordlist generation enhance flexibility. Skipfish generates detailed HTML reports for professional security assessments, making it ideal for ethical hackers, penetration testers, and webmasters.

Bully is a robust open-source wireless network auditing tool for ethical hacking, seamlessly integrated into Kali Linux (version 2024.06.R1). As a Wi-Fi Protected Setup brute-force tool for cybersecurity, it targets WPS vulnerabilities to recover WPA/WPA2 passphrases, making it a top wireless password recovery tool for penetration testing. Written in C with a 1.4 MB size, Bully offers improved performance over Reaver, supporting Pixie-Dust attacks for rapid PIN cracking.

Nishang is an open-source PowerShell framework tailored for offensive security, penetration testing, and red teaming, pre-installed on Kali Linux at /usr/share/nishang. It offers a collection of scripts and payloads designed to facilitate reconnaissance, privilege escalation, backdooring, and data exfiltration in Windows environments. Developed by Samrat Ashok, Nishang leverages PowerShell’s native integration with Windows to execute attacks in memory, evading traditional antivirus detection. Its modular structure, organized into categories like Powerpreter, Backdoors, and Gather, makes it a versatile tool for ethical hackers and security researchers.
