  2. Paste the modified YAML into the right panel.
  3. Click Compare to see the highlighted differences.
  4. Use Split or Unified view to review changes.

FAQ

Does YAML Diff validate syntax?

The tool compares YAML as plain text, so it works even with non-standard YAML dialects.

Is my YAML data private?

Yes — everything runs in your browser. No data is sent to any server.

Can I compare multi-document YAML files?

Yes. Paste the full content including document separators (---) and they will be compared line by line.
