CST VerdictBased 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 running routine web app assessments will find IntruderPayloads valuable for payload library depth without licensing friction; the 3,845 GitHub stars indicate active community curation of attack vectors that stay current without vendor gatekeeping. This free model works best for individual practitioners and small consultancies that iterate fast and don't need commercial support or integration with enterprise ticketing systems. Skip this if your team relies on guided workflows and remediation tracking; IntruderPayloads is payload reference, not a full pentest platform.
