JS-Scan vs Yasuo: 2026 Comparison
JS-Scan is a free security scanning tool. Yasuo is a free security scanning tool. Compare features, ratings, integrations, and community reviews side by side to find the best security scanning fit for your security stack.
CST VerdictBased on our analysis of available product data, here is our conclusion:
Developers and security engineers auditing their own JavaScript codebases for injection vulnerabilities will find JS-Scan useful for its simplicity; it runs free and requires no setup beyond PHP, making it accessible for quick local scans before commit. The 222 GitHub stars indicate modest but steady adoption among teams doing their own scanning rather than waiting for a vendor tool. Skip this if you need vulnerability tracking across multiple repositories, remediation workflows, or integration with your CI/CD pipeline; JS-Scan is a point scanner, not a platform.
DevSecOps teams operating on minimal budgets will get real value from Yasuo because it does one thing well: finding vulnerable third-party web applications already sitting in your network, which most scanners miss or charge heavily for. The 573 GitHub stars and active Ruby community mean it's battle-tested enough for production use without licensing friction. Skip this if you need scanning for custom code or containerized applications; Yasuo is specifically built to hunt known exploits in off-the-shelf software, not your own vulnerabilities.
