Compare
Snyk finds and helps remediate application-security risk. FalseGreen can verify declared security conditions and decide whether the complete bounded engineering outcome satisfied its frozen requirements.
Quick answer
Snyk is a developer-security platform spanning first-party code, open-source dependencies, containers, and infrastructure as code. FalseGreen is not a Snyk replacement. If you need vulnerability and configuration scanning, use a dedicated security product; use FalseGreen when the broader question is whether one consequential Job was independently established.
Alternative or additional layer?
No—not if you need a developer-security platform or vulnerability scanner. Snyk remains the specialist for code, dependency, container, and infrastructure security. FalseGreen can use relevant security results as evidence when independently deciding whether the broader Job is complete.
What Snyk is good at
Where the overlap is
Both can surface reasons not to trust a software change. Snyk focuses on developer and application security findings; FalseGreen can include relevant security results among the evidence for a broader, human-defined engineering outcome.
The architectural difference
Snyk evaluates supported artifacts against security intelligence and configured security policies. FalseGreen can verify declared security conditions too, then freezes the bounded definition of done and asks whether heterogeneous evidence establishes the complete outcome. A clean security scan is valuable, but it does not establish missing business behavior or every other Job criterion.
Beyond scanner output
FalseGreen overlaps with Snyk wherever it produces code, review, or security evidence. Scanners answer a scoped question; FalseGreen combines that evidence with software behavior, formal obligations, rendered UI, exact source, and the definition of done frozen before judgment—then returns Accepted, Failed, or Insufficient Evidence.
Software
Verify the requested behavior and state.
Formal
Bind Lean proof evidence to exact obligations.
Security
Assess scoped security evidence without making a clean scan the whole verdict.
UI + source
Check rendered outcomes and exact-source identity.

FalseGreen PR Gate enforces existing exact-source acceptance for Job-backed pull requests; it does not perform verification. “Not primary” describes product scope, not an unsupported universal absence claim.
When to choose Snyk
Choose Snyk when your central problem is finding, prioritizing, monitoring, and fixing vulnerabilities across application code, dependencies, containers, or infrastructure configuration.
When to use FalseGreen
Use FalseGreen when a security-sensitive or otherwise consequential Job needs an independent acceptance decision over the complete agreed outcome, with the security evidence kept in its proper scope.
Better together
Snyk can remain the dedicated security engine. Its findings can inform FalseGreen verification without turning FalseGreen into a vulnerability scanner or treating a green scan as proof that the whole Job is done.
The builder layer stays open
The coding-agent layer remains swappable. FalseGreen sits outside the builder, regardless of which supported agent or underlying model performs the implementation.
