CST VerdictBased on our analysis of available product data, here is our conclusion:
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.
Development teams shipping Python and Node.js packages should use GuardDog for pre-publication malware screening because its heuristics-based approach catches obfuscated and supply-chain attacks that signature-based tools miss. The CLI integrates directly into CI/CD pipelines at zero cost, catching malicious dependencies before they reach registries. Skip GuardDog if you need runtime monitoring of already-installed packages or deep visibility into legitimate but vulnerable code; it's built for prevention at the source, not forensics on deployed systems.
