How to use HAR Sanitizer & Replay Packager
Upload or paste a HAR file captured from browser DevTools. The tool scans all requests and responses for sensitive values — cookies, auth headers, tokens — and lets you redact them before sharing. You can also export a cleaned HAR or a cURL replay package.
Common use cases
Security teams use this to safely share traffic captures from production without leaking credentials. QA engineers use it to create sanitised HAR files for bug reports and hand them to developers, and API teams use it to package real-world request examples for documentation.
