Crash Key-Value Reporter

Add key-value pairs of crash metadata. Then simulate a fault — the captured Reporting payload below shows exactly what would be POSTed to your reporting endpoint, including your attached keys.

Origin trial / behind a flag

Real navigator.crashReporter requires Chrome 140+ with chrome://flags/#enable-experimental-web-platform-features and a Reporting-Endpoints header. This demo simulates the attachment locally so you can see the report shape.
