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.
Development teams managing open-source dependencies at small to mid-market scale should use npm-zoo for fast, zero-friction screening of known malicious packages before they enter your supply chain. The tool's strength is specificity: it maintains a curated blocklist rather than attempting broad vulnerability scoring, which means fewer false positives and faster decisions at code review time. Skip this if you need continuous monitoring across your entire dependency tree or integration with your existing SCA platform; npm-zoo is best deployed as a gating check, not a replacement for deeper composition analysis.
