Socket.dev
Supply chain malware detection
Free tier + paidCode review, testing & securitysocket.dev
What it is
Inspects what a package actually does rather than only matching published CVEs, detecting 70+ risk types including install scripts, unexpected network or filesystem access, obfuscated code, typosquats and outright malware. It comments on the pull request when a dependency change introduces new capabilities. Higher tiers add reachability analysis to cut CVE noise.
Why it earns a slot
This is the direct answer to AI package hallucination and slopsquatting. When your agent adds a convincing-sounding package published last week that phones home on install, Socket blocks the pull request.
Know before you commit
Team carries a 5-developer minimum, a $125/mo floor, and Business a 20-developer minimum, so small teams pay for seats that do not exist.
Getting started
Install the Socket GitHub App for PR comments, or run npx socket in CI
