How JSON compare works
Paste a baseline JSON document on the left and a candidate document on the right. PayloadHarbor parses both locally, then reports added, removed, and changed paths such as $.user.roles[1].
Best use cases
- Compare API versions before and after a deploy.
- Review webhook payload drift between environments.
- Spot changed configuration keys without uploading sensitive payloads.
