Why this is a webhook inspector, not just a JSON formatter

Provider-aware event detection, exact raw-body verification, replay-risk analysis, structure drift, sensitive-field scanning and safe replay generation are all local.
For production capture, OneFreePlace can add a short-lived same-origin receiver endpoint. The browser preview intentionally does not upload payloads or secrets to a third party.
