• 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.

• Far more configurable than Dependabot — grouping, scheduling and automerge rules that keep PR volume sane.
• Supports dozens of package managers including Docker, Terraform, Helm and GitHub Actions.
• Free hosted app, or self-host it entirely.

• 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.

• The configuration surface is large enough to be its own learning curve.
• Without careful grouping rules it produces a lot of pull requests.
• Vulnerability context is thinner than a dedicated SCA tool.

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

Teams that outgrew Dependabot's limited configuration and want update policy under control.
