+
+The [Crash Reporting API](/en-US/docs/Web/API/CrashReport) provides a way for sites to include diagnostic data in browser crash reports sent through the [Reporting API](/en-US/docs/Web/API/Reporting_API).
+It exposes the {{domxref("Window.crashReport")}} property and the {{domxref("CrashReportContext")}} interface, which store key-value data for the current top-level browsing context.
