      What this tool does

      Compare two JSON configurations locally and get a risk-labelled list of differences with secret values masked.

      Limits and safe use

      JSON objects up to 200,000 characters each, 5,000 values and 20 levels deep. Nothing is applied to any system. Review the report before relying on it. It is a deterministic check, not a certification, and it does not send data to a server or a model.
