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.
Penetration testers and security researchers doing reconnaissance will find WhatWeb invaluable for passive technology fingerprinting across hundreds of targets simultaneously; its plugin architecture identifies 6,000+ web technologies and CMS variants that commercial scanners miss or charge extra to detect. The tool's free, open-source nature and 6,054 GitHub stars mean you get maintained detection rules without vendor lock-in. Skip this if you need active vulnerability scanning or compliance reporting; WhatWeb stops at "what's running," not "what's broken.
