CST Verdict

Based on our analysis of core features, integrations, here is our conclusion:

CORSy

DevSecOps teams scanning third-party APIs and SaaS integrations will get the most from CORSy because it catches CORS header misconfigurations that let attackers bypass same-origin policy restrictions; most teams never audit this attack surface until it causes a breach. The tool is free and command-line native, which means it fits into CI/CD pipelines without licensing friction or vendor lock-in. Skip this if you need a GUI, reporting dashboards, or coverage beyond HTTP header analysis; CORSy is deliberately narrow and won't replace a full web application scanner.
