Does this tool connect to my Azure account?

No. This tool runs entirely in your browser and generates configuration JSON that you can copy and paste into your infrastructure-as-code templates, CLI commands, or cloud console. It never connects to any cloud account or sends data externally.

Are the generated configurations production-ready?

The tool produces syntactically valid configurations based on current Azure service specifications. Always review generated configs against your organization security policies and test in a non-production environment before deploying.
