DEVELOPER DIAGNOSTICS · CONTROLLED ENDPOINT

HTTP response inspector

Inspect one signed, controlled HTTP response: status, safe headers, payload correlation and browser-reported protocol.

Checking network test availability…

Test this browser’s path to our endpoint

No website URL, credentials or test account is required. This checks our controlled endpoint, not an arbitrary API or another website. Nothing runs until you press the start button.

Requests
1 sequential probe
Response read limit
4 KiB per probe
Request deadline
2 seconds
Run deadline
20 seconds, plus bounded cleanup

Admission reserves an 8 MiB allowance; it does not transfer 8 MiB. Each probe conservatively debits 256 KiB of that allowance. Request headers and admission traffic are additional to the response-body limit.

What this can and cannot establish

These are browser-to-Worker HTTP observations, including application handling and quota checks. They do not isolate Wi-Fi, router, ISP, DNS or TLS delay. Negotiated protocol is reported only when the browser exposes it; unavailable data is not guessed.

A failed request can have several causes. Compare controlled runs under the same conditions and keep this tab in the foreground. No traffic shaping, arbitrary-site scanning or system-wide fault injection is performed.
