A website broke.
Send evidence, not guesswork.

A HAR is the browser's recording of what happened while a page failed. ReqRescue finds the likely failure points, removes common secrets, and turns that recording into a ready-to-send bug report. The file never leaves this tab.

Need a HAR? Export one in 3 steps.

A HAR is a browser recording of the network requests made while a page loads or a problem happens. It helps support and engineering see failed API calls, slow requests, redirects, and status codes.

  1. Open the broken page, then open Developer Tools.
  2. Select Network, reload the page, and reproduce the issue.
  3. Export or save all requests as HAR, then open that file here.
Chrome / Edge: F12 → Network → Export HAR. Firefox: F12 → Network → Save all as HAR.

ReqRescue, in plain English

A safer, faster handoff when a website breaks.

ReqRescue reads a browser network recording, finds the requests most likely connected to the failure, removes common secrets, and packages the useful evidence for the person who has to fix it.

WHAT GOES IN

A HAR network recording

A standard file exported from your browser after you reproduce a broken checkout, login, upload, dashboard, or other web flow.

WHO IT IS FOR

Support, QA, developers, and technical founders

Anyone who needs to turn “it does not work” into evidence an engineer can inspect without another round of questions.

WHAT COMES OUT

A diagnosis, clean HAR, and ready-to-send report

Ranked suspects with confidence, cited request evidence, detected privacy risks, and a Markdown handoff for Jira, GitHub, Slack, or AI.

01

The support ritual, compressed

Sanitizing is step one.
Explaining is step two.

A viewer hands you hundreds of rows. A sanitizer removes risk. ReqRescue does both, then performs the first triage pass an experienced support engineer would do—and shows its work.

01

Reconstruct the failure

Group repeated failures, trace status patterns, isolate slow-tail requests, and spot redirect loops that keep the browser in circles.

02

Separate fact from hypothesis

Every suspect carries a confidence level and the exact requests that support it. No invented root cause.

03

Make the evidence shareable

Strip cookies, auth headers, tokens, passwords, emails, IPs, private hosts, and sensitive body fields.

Privacy architecture

Your trace never takes a network trip.

Parsing, triage, and file generation run in this tab. We record only pseudonymous product events such as “demo analyzed” or “report exported,” using a random identifier stored in this browser—never file names, URLs, headers, bodies, or HAR contents.

Trust, before upload

The questions a sensitive
trace deserves.

ReqRescue is deliberately local, deterministic, and explicit about uncertainty. No account is required.

Does ReqRescue upload my HAR file?

No. Parsing, ranking, redaction, and export generation happen in your browser tab. The server never receives the HAR, its file name, request URLs, headers, or bodies.

What sensitive data does it remove?

ReqRescue strips request and response bodies, cookies, authorization headers, API keys, access and refresh tokens, passwords, emails, IP addresses, private hosts, URL credentials and likely identifiers in paths. It also drops unknown vendor fields. Automated redaction cannot guarantee recognition of every product-specific secret, so review every export before sharing it.

How is this different from a HAR viewer or sanitizer?

A viewer helps you inspect requests. A sanitizer removes secrets. ReqRescue also groups failures, ranks evidence-backed suspects, and produces a Markdown incident report plus a clean HAR for engineering or support.

Does it claim to know the root cause?

No. ReqRescue separates observed facts from hypotheses. Each suspect has a confidence level and the exact requests that support it, so an engineer can verify the diagnosis instead of trusting a black box.

Can I try it without a real trace?

Yes. Run the 15-second broken-checkout demo above. It uses a synthetic HAR with repeated authentication failures and fake secrets, so you can inspect the complete report safely.
