When is JSON Diff useful?
JSON Diff is useful when two API responses look similar but behave differently. Path-based comparison makes structural and value changes easier to identify than scanning raw text line by line.

Frequently asked questions
Are both JSON documents processed locally?
Yes. The comparison runs in your browser during normal tool use.
Is JSON Diff the same as text diff?
No. DevPayload compares parsed JSON paths and values, which reduces noise caused only by whitespace or formatting.
Do I need an account?
No. Public deterministic tools work without signing in.
