Report viewer

Paste a Reporting API crash payload — or use the included samples — and the viewer renders the new call-stack frames Chrome 137 attaches when the page hangs. Sample payloads are real shape, fields lifted from the spec.

Origin trialThe full server-side feature ships on report-uri endpoints. The viewer below is an offline parser — it works for any payload you paste or upload, including the sample reports.

the format

Chrome 137 adds a stack array to crash body reports posted to your Report-To / Reporting-Endpoints URL. The top frame is where the renderer was wedged when the unresponsive timer fired.

{
  "type": "crash",
  "url": "https://example.com/checkout",
  "body": {
    "reason": "unresponsive",
    "stack": [
      { "function": "applyCoupon", "source": "checkout.js", "line": 412, "column": 19 },
      { "function": "<anonymous>",   "source": "vendor.js",   "line": 8841, "column": 5 }
    ]
  }
}
