Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Grype

  • Depends on public vulnerability databases, so coverage and false positives vary by ecosystem
  • No triage, exception tracking or reporting UI — that is Anchore’s commercial product
  • Overlaps heavily with Trivy, and most teams pick one rather than running both

Swagger/OpenAPI

  • The OpenAPI Specification itself is licensed under Apache License 2.0 and free to use; SwaggerHub is a separate paid tool built on top of it
