Reconstruct the failure
Group repeated failures, trace status patterns, isolate slow-tail requests, and flag redirect churn.
Free HAR analyzer + sanitizer
Stop sending raw traces.
Send the case.
ReqRescue turns a browser HAR into a ranked incident brief, a scrubbed evidence file, and a bug report your engineer can act on— without uploading the trace.

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

Privacy architecture
Your trace never takes a network trip.
Parsing, triage, and file generation run in this tab. We record only anonymous product events such as “demo analyzed” or “report exported”— 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 cookies, authorization headers, API keys, access and refresh tokens, passwords, emails, IP addresses, private hosts, and sensitive request or response body fields. You should still review any exported evidence 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.
