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 Snyk?
No — except free alerts between Jobs. A FalseGreen Job checks dependencies on the exact source at verification time, names the fix, and blocks acceptance on what it finds.
What Snyk does
What it does well.
- Continuous dependency and container scanning across many ecosystems
- A large curated vulnerability database
- Dashboards and policies across an entire fleet of repos
The replacement
Free Dependabot + one FalseGreen Job covers Snyk.
FalseGreen Job — before merge
This replaces Snyk.
Replace the SCA subscription for your Rust work with five security classes inside every verdict — plus the supply-chain drift gate no SCA tool runs.
The feature matrix
FalseGreen vs Snyk, line by line.
| Capability | FalseGreen | Snyk |
|---|---|---|
| Primary purposeThe main problem the product is designed to solve. | Independent whole-program acceptance | Developer and application 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 | — Not primary |
| 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 |
