Socket, OpenSSF Scorecard, Snyk, and npm audit are excellent tools. None of them measure behavioral commitment signals — the structural conditions that make a package a high-value target before any attack code is published.
| Tool | What it measures | Commitment signals? | Supply chain depth? | Free tier? |
|---|---|---|---|---|
| Commit | Behavioral commitment signals — publish frequency, maintainer count, download/maintainer ratio, lock file hygiene, deprecation handling | ✅ Core focus | ✅ Full tree | ✅ Unlimited |
| Socket.dev | Code-level analysis — static inspection for malicious patterns, network calls, obfuscated code, typosquatting, known malware | ❌ | Partial | Freemium |
| OpenSSF Scorecard | Repository security practices — branch protection, CI/CD, signed releases, SAST, fuzzing, token permissions | ❌ | ❌ Single repo | ✅ Free |
| Snyk | Known vulnerabilities — CVE database, exploit availability, fix guidance, dependency upgrade paths | ❌ | ✅ | Freemium |
A package can score A+ on Snyk (no known CVEs), 9/10 on Scorecard (great practices), pass Socket inspection — and still be CRITICAL on Commit because one credential controls 100M weekly installs with no org backup. They answer different questions.
Best for: detecting active attacks after malicious code is published.
Best for: auditing whether a project follows security best practices.
Best for: finding known vulnerabilities with published fixes.
Best for: mapping structural exposure before any attack occurs.
Five widely-used packages. npm audit (and by extension Snyk/Socket for CVEs) shows zero issues. Commit shows which ones are structurally exposed.

No. Use both. Socket detects malicious code after it's published — it's an active threat detector. Commit identifies structural exposure before any code changes — it's a risk map. They're complementary: Socket tells you "this version is compromised," Commit tells you "this package is the kind of thing that gets targeted."
Scorecard checks whether a project follows security practices — branch protection, signed commits, fuzzing. A project can score 9/10 on Scorecard and still have one person controlling the npm publish token for 100M weekly installs. Scorecard also requires a GitHub repo; it can't assess npm-only packages or walk your full transitive tree. Commit focuses specifically on credential concentration at scale.
Snyk is excellent at finding known vulnerabilities — CVEs with published exploits. But supply chain attacks are not exploits of known CVEs. The axios attack in April 2026 had zero Snyk warnings beforehand. The attacker didn't exploit a CVE — they compromised a single maintainer's credentials. Snyk can't warn you about a vulnerability that doesn't exist yet. Commit flags the structural conditions that make that attack possible.
CRITICAL isn't a judgment on the maintainer or the code. chalk is excellent. esbuild is extraordinary. The flag means "one set of credentials controls infrastructure-level download volume with no organizational backup." That's a structural observation about the ecosystem, not the person. If anything, it's an argument that the ecosystem should be funding and backing these maintainers — not leaving them as single points of failure for billions of installs.
