AuditJS is a free software composition analysis tool. Chainguard Libraries is a commercial software composition analysis tool by Chainguard. Compare features, ratings, integrations, and community reviews side by side to find the best software composition analysis fit for your security stack.
Based on our analysis of NIST CSF 2.0 coverage, core features, company size fit, deployment model, here is our conclusion:
JavaScript teams shipping npm packages on tight release cycles should use AuditJS for its zero-friction dependency scanning; it runs offline via command line and integrates directly into CI/CD without vendor lock-in. The tool covers the most common attack vector in Node ecosystems,transitive dependency vulnerabilities,and the 230 GitHub stars reflect active adoption among teams that value simplicity over breadth. Skip AuditJS if you need runtime vulnerability detection, license compliance scanning, or policy enforcement across polyglot codebases; it's deliberately narrow, scanning only declared npm dependencies against known databases.
Teams shipping Python and Java applications will cut their supply chain attack surface by rebuilding libraries from verified source rather than trusting precompiled binaries; Chainguard Libraries covers 55K+ Java projects and 15K+ Python projects with SLSA Level 2 build guarantees and full provenance tracking. The malware-resistant registry distribution model is genuinely different from traditional SCA tools that only flag vulnerabilities after they're public. This is not for organizations still evaluating whether they need SCA at all, or teams without the infrastructure maturity to integrate artifact management into their pipelines.
AuditJS is a command-line tool that scans JavaScript projects for known vulnerabilities and outdated packages in npm dependencies using the OSS Index API or Nexus IQ Server.
