FAQ
Does YAML key order matter?
No. Mapping key order is ignored, so reordering keys does not create a semantic difference.
Does array order matter?
Yes. YAML sequences are ordered, so changing item order is reported as a difference.
Are my YAML files uploaded?
No. Your YAML is parsed and compared locally in your browser.
Are comments compared?
No. Comments and formatting are not part of the parsed YAML structure, so comment-only changes are ignored.
Can I compare .yml files?
Yes. You can open .yaml, .yml, and .txt files.
