Frequently asked questions
Does key order or whitespace matter?
No. The comparison is structural, so reordered keys and different formatting are not reported.
How are arrays compared?
By index by default. You can also ignore array order to compare arrays as sets of values.
Can I compare API responses?
Yes, it is ideal for spotting what changed between two API responses or config files.
