Frequently Asked Questions

The tool parses both YAML documents into objects, then performs a deep comparison to identify additions (new keys), deletions (removed keys), and modifications (changed values).

Yes. Deeply nested objects and arrays are compared recursively with full path information shown for each difference.

By default, arrays are compared by index position. You can enable 'ignore array order' to compare arrays as sets, ignoring element position.

Yes. All comparison happens entirely in your browser using JavaScript. No data is sent to any server or third party.

Absolutely. Perfect for comparing different versions of Kubernetes configs, Docker Compose files, GitHub Actions, or any YAML configuration.

Added items are shown in green, removed items in red, and modified values in yellow with before/after comparison. Each difference shows the full path.

Yes, but very large files (>1MB) may take time to compare. Performance depends on your browser and device capabilities.

Indentation differences don't affect comparison. YAML is parsed to objects first, so formatting differences are ignored unless they change the structure.

Yes. YAML anchors (&), aliases (*), and merge keys (<<) are fully supported. The comparison works on the resolved values after anchor/alias expansion.
