ysoserial.net is a free penetration testing tool. Payloads All The Things is a free penetration testing tool. Compare features, ratings, integrations, and community reviews side by side to find the best penetration testing fit for your security stack.
Based on our analysis of available product data, here is our conclusion:
.NET penetration testers and red teamers validating deserialization defenses will find ysoserial.net indispensable; it's the only free payload generator that consistently produces working exploits against ObjectDataProvider, WindowsIdentity, and other high-impact gadget chains without requiring paid commercial alternatives. The tool has 3,544 GitHub stars and remains actively maintained, meaning payloads stay current as .NET frameworks patch old chains. Skip this if your team needs graphical UI workflows or integration with existing Burp/Metasploit pipelines; ysoserial.net is command-line only and demands manual payload delivery.
Penetration testers and red teamers building custom test cases should use Payloads All The Things as a living reference library; its 76,000 GitHub stars reflect years of community-driven validation across SQLi, XSS, CSRF, and dozens of other vectors. The real value is that it's freely maintained by practitioners who actually exploit these gaps, so payloads stay current with real-world bypasses rather than textbook examples. Skip this if you need a polished UI, guided workflows, or integration with your vulnerability scanner; Payloads All The Things is raw material for people who know what they're hunting for.
