Snyk

Developer-first security platform that finds and fixes vulnerabilities in code, open-source dependencies, containers, and infrastructure as code.

Add automated dependency vulnerability scanning to your GitHub Actions CI pipeline
Scan container images for OS-level CVEs before pushing to a registry

200 SCA tests, 100 SAST tests, 300 IaC tests, 100 container tests per month

Start with the Free plan — no credit card needed. Focus your 200 monthly SCA tests on your most actively-maintained repositories. Use the CLI (`snyk test`) in CI to scan on every PR instead of manually. Prioritize Snyk Code (SAST) for your own application code — the 100 tests/month are enough for a small-to-medium codebase scanned weekly. Enable GitHub integration for automatic PR checks. If you hit the test limit mid-month, defer lower-priority scans to the first of next month when credits reset.

Sign up at snyk.io → install the CLI (`npm i -g snyk`) → run `snyk auth` to authenticate → run `snyk test` in your project directory → connect your GitHub/GitLab repo for automatic PR monitoring → review the Snyk dashboard for vulnerability details and fix recommendations.

Pros

  • Multi-vector scanning: Covers open source (SCA), custom code (SAST), containers, and IaC in one platform — no need for separate security tools
  • Developer-first UX: IDE plugins for VS Code/JetBrains show vulnerabilities inline, and PR checks block merges on critical issues
  • Fix guidance: Every vulnerability comes with actionable fix advice — auto-upgrade, patch, or alternative package suggestions

Cons

  • Monthly test caps: Free tier limits (200 SCA, 100 SAST) run out fast on active monorepos — you'll need to prioritize which repos to scan
  • No custom rules on free: Custom security rules and risk-based prioritization require the Ignite plan ($1,260/year)
  • False positives: SAST scanning can produce noisy results on dynamically-typed languages — requires tuning to reduce alert fatigue
