JS Library Vulnerability Checker
Detect JavaScript libraries, identify outdated components, and review safer upgrade priorities.
Best for frontend teams, app owners, and agencies reviewing older codebases, vendor bundles, or post-release dependency hygiene.
What This Tool Checks
- Library and version evidence extraction
- Outdated component risk flags
- Safer upgrade recommendations
Why It Matters
Outdated client-side libraries can leave known weaknesses in production even when backend systems are tightly controlled. Dependency drift is easy to miss when bundled assets hide the version story.
Best For
Best for frontend teams, app owners, and agencies reviewing older codebases, vendor bundles, or post-release dependency hygiene.
What To Do Next
Use the findings to confirm which libraries are still active, then prioritize upgrade or removal work based on exposure and real production usage.

What does the JS Library Vulnerability Checker look for?
JS Library Vulnerability Checker focuses on library and version evidence extraction, outdated component risk flags, safer upgrade recommendations. It is designed to help teams identify this category of weakness quickly and then move into broader workflows if deeper follow-up is needed.
What is the difference between Quick and Comprehensive mode?
Quick mode stays public for focused diagnostics. Comprehensive mode is intended for authenticated workflows where users need saved history, richer follow-up, and broader account-linked execution.
When should I use the full Vulnify platform instead?
Use the full platform when you need more than one focused diagnostic, want to keep reports and history, or need scheduled scans, exports, and broader vulnerability coverage beyond js library vulnerability checker.
