- Can I migrate from Snyk?
- Yes. Start with the workflows or data you actually use, then cut over. The Trivy / Grype stack page has the agent prompt and the cost table; most teams rebuild the slice that matters and leave old Snyk links until they expire.
- How do I deploy it?
- Open the Trivy / Grype stack, copy the agent prompt, and deploy on Railway (one service, PORT, and a volume when the app needs disk). These are CLI/CI jobs, not a hosted app. Run Trivy or Grype in the pipeline that already builds the image. Start on Railway only if you also want a registry to scan — that stack is /stacks/harbor-registry. No one-click scanner template in this repo.
