FAQ

Why is semantic YAML diff better than standard Git diff for Kubernetes manifests?

Kubernetes manifests often change key order or indentation levels between Helm renders or Kustomize overlays. Semantic YAML diff compares actual configurations and resource specs rather than whitespace, highlighting real infrastructure modifications.

Can I diff multi-document YAML files containing multiple resources (---)?

Yes. The YAML diff engine parses multi-document streams and aligns corresponding deployments, services, and configmaps.

Is my cloud infrastructure configuration data kept private?

Yes. FormJson runs 100% locally in your browser. No Docker Compose files, Kubernetes manifests, or cloud secrets ever leave your browser.
