CodeQL vs Snyk

Feature checklists rarely decide anything. What decides it is the pricing metric, who has to write the tests, and which limitation you can live with.

Entry price

From $30 per active committer/month (GitHub Code Security)

Free tier

From $25 per contributing developer/month (indicative, Team)

Free tier

What drives the bill

The metric that actually scales your invoice.

Free on public repos. For private repositories GitHub split Advanced Security into two products in April 2025: Code Security at $30 and Secret Protection at $19 per active committer/month, both now available on Team plans as well as Enterprise. CodeQL sits in Code Security. Billing counts active committers, not seats, which can surprise teams with many occasional contributors.

Priced per contributing developer. Enterprise agreements add reporting and governance and get expensive.

Free tier

Free for public repositories on GitHub.

Free plan with a monthly test allowance, generous enough for small projects.

Strengths

  • Interprocedural dataflow analysis finds real vulnerabilities that regex- and pattern-based tools cannot see.
  • Free on public repositories, with results in the GitHub security tab.
  • Custom queries let you encode organisation-specific security rules.
  • Reachability analysis dramatically cuts the noise from transitive dependency alerts.
  • Automated fix pull requests make remediation a merge rather than a project.
  • One vendor covers dependencies, code, containers and IaC.

Limitations

  • Writing custom CodeQL queries is a specialist skill with a steep learning curve.
  • Analysis is slow — minutes to tens of minutes, so it fits nightly better than per-commit.
  • Private-repo licensing through Advanced Security is expensive at scale.
  • Per-developer pricing scales uncomfortably in large engineering organisations.
  • SAST is less deep than dedicated code-analysis vendors.
  • Still produces substantial alert volume on older codebases.

Best for

GitHub-hosted projects wanting deep static security analysis, free if the repo is public.

Engineering teams that want security findings arriving in the pull request with a fix attached.

All of these integrate with: VS Code, Jenkins.
