Crash triage console
Apply realistic scenario presets — "checkout flow", "video player", "long-running document" — to populate crashReporter key-value pairs, then inspect what a future crash report would carry. Useful for designing your crumb taxonomy.
Behind a flag. Enable
chrome://flags/#crash-reporter-kv-api.
Without the flag, this page falls back to an in-memory shim so you can still rehearse the API.

// crashReporter is the new global. Each key-value pair is attached to any
// crash report Chrome generates for this document, surfacing inside the
// report's "Annotations" panel.
crashReporter.set('step', 'payment');
crashReporter.set('order_id', '8742');
crashReporter.set('cart_items', String(items.length));
// Later, when a different flow ends:
crashReporter.delete('order_id');
// Iterate everything you've set:
for (const [k, v] of crashReporter.entries()) {
console.log(k, '=', v);
