HAR File Inspector

Upload a HAR (HTTP Archive) file to inspect network traffic, diagnose failures, and export a safer sanitized copy.

What this tool does

HAR Viewer — Browse every request, status code, domain, MIME type, transfer size, and timing breakdown.
Network Autopsy — Highlights failed requests, status 0/CORS-looking failures, slow calls, huge responses, redirects, cache misses, and heavy third-party traffic.
Privacy Scanner — Detects cookies, authorization headers, API keys, tokens, session IDs, and secret-looking request values.
HAR Sanitizer — Redacts sensitive headers, cookies, query params, JSON/form body fields, private IPs, and optionally strips request/response bodies.
Export Tools — Download a sanitized HAR, generate a Markdown bug report, or copy a sanitized curl repro for a selected request.

Privacy

HAR files can contain passwords, cookies, API tokens, page contents, and personal data. This tool runs entirely in your browser. Your HAR file is not uploaded to Bitgate or any third-party server.

Safety note

No automated sanitizer can guarantee perfect removal of every possible secret. Always review sanitized files before sharing them with support, vendors, or strangers on the internet.
