GitHub Dependabot — free
Keep this one.
Continuous alerts for known vulnerable dependencies across every repo, from GitHub, for $0. That's the only scanner you need — because the other kind of checking moves inside the Job.

Do you still need Sonar?
No. Sonar scans code and reports problems; a FalseGreen Job fails the verdict until they are fixed — on a real build and your real tests, not just pattern rules.
What Sonar does
What it does well.
- Repository-wide quality, duplication, and coverage metrics
- A configurable quality gate inside CI
- Years of technical-debt tracking across languages
The replacement
Free Dependabot + one FalseGreen Job covers Sonar.
FalseGreen Job — before merge
This replaces Sonar.
Replace the quality-gate subscription with a Job that runs the checks and stops the release — plus security and proofs the quality gate never attempted.
The feature matrix
FalseGreen vs Sonar, line by line.
| Capability | FalseGreen | Sonar |
|---|---|---|
| Primary purposeThe main problem the product is designed to solve. | Independent whole-program acceptance | Static code quality and security |
| Dedicated security or static analysisSpecialized analysis for code quality, vulnerabilities, or security findings. | ✓ Yes | ✓ Yes |
| Frozen human-defined definition of doneThe frozen acceptance target is established before implementation is judged. | ✓ Yes | ◐ Partial |
| Frozen Job target preserved through repairThe agreed Job target remains authoritative while the implementation is repaired and reverified. | ✓ Yes | ◐ Partial |
| Separate Job acceptance authorityA distinct authority decides whether the FalseGreen Job is accepted. | ✓ Yes | — Not primary |
| Job or outcome-level acceptanceAnswers whether the whole program meets the agreed definition of done. | ✓ Yes | — Not primary |
| Exact-source-bound acceptanceAcceptance belongs explicitly to the exact source state that earned it. | ✓ Yes | ◐ Partial |
| Repair against unchanged requirementsRepairs can be reverified while the original acceptance target remains frozen. | ✓ Yes | ◐ Partial |
| Heterogeneous evidence for acceptanceTests, CI, scanners, formal tools, behavior, and inspection can inform one Job decision. | ✓ Yes | ◐ Partial |
| Explicit verdictReturns Accepted, Failed, or Insufficient Evidence for the verified program. | ✓ Yes | ◐ Partial |
| Re-checkable evidence and limitationsPreserves what was checked, the relevant source, supporting evidence, and limitations. | ✓ Yes | ◐ Partial |
