FAQ
- How do I compare JSON online?
- Paste the original JSON on the left and the new JSON on the right. The diff updates as soon as both sides are valid.
- Is this JSON diff free?
- Yes. The browser-based JSON Diff tool is free and does not require an account. Monitoring live APIs over time is what APIDiffGuard productizes.
- What is the difference between a JSON diff and API monitoring?
- A JSON diff compares two static payloads once. APIDiffGuard captures a baseline response, re-checks the endpoint on a schedule, and alerts when the live response drifts.
