CST VerdictBased on our analysis of available product data, here is our conclusion:
Supply chain teams managing dependencies across multiple package managers will get the most from Lockfile Linting because it catches policy violations and known vulnerabilities in lockfiles before they reach production, catching what many SCA tools miss by only scanning source code. The tool is free and carries 843 GitHub stars, making it low-friction to deploy in CI/CD pipelines without budget approval. Skip this if your team needs deep transitive dependency analysis or license compliance reporting; Lockfile Linting is deliberately narrow, checking what's actually locked rather than mapping the full dependency graph.
JavaScript teams shipping packages to npm or yarn registries should use pkgsign if supply chain provenance matters more than ease of adoption. The tool cryptographically signs packages at build time and verifies signatures on install, closing a real gap in npm's default threat model; 95 GitHub stars suggests early traction among teams that already think in terms of package authenticity. Skip this if your workflow demands a GUI or integration with existing SCA platforms; pkgsign is a CLI primitive that requires you to own the signing ceremony in your pipeline.
