Stack Source Mapper
Crash reports from unresponsive pages can include the JavaScript stack as an Error.prototype.stack-style string. This tool parses that stack, applies a compact source-map lookup to minified frames, and shows how an endpoint can group a hang by the original source location.

Reporting endpoint preview
Click "Build endpoint preview" to generate a sample incoming crash report plus the derived endpoint analysis.
Chrome 137 change: When the crash
reason is
unresponsive and the document policy
include-js-call-stacks-in-crash-reports is enabled, the crash report body can
include stack as the same string representation used by
Error.prototype.stack. Production source maps are applied after delivery at the
reporting endpoint; they are not raw addresses in the browser report.
