Why Redacting HAR Files is Essential for Enterprise Security
HTTP Archive (HAR) files capture raw network telemetry recorded during a browser session. When developers share HAR captures with third-party technical support or bug bounty teams, these archives often secretly contain Bearer tokens, session cookies, API secrets, and unmasked credit card numbers in request headers and POST bodies.
100% In-Browser Privacy & Performance Waterfall
This analyzer renders network timing waterfalls (DNS, SSL, TTFB, Content Download) entirely inside local browser memory. Click 'Redact & Export Clean HAR' to scrub all credential patterns with zero external network transmission.
Frequently asked questions
What sensitive information does a HAR file usually contain?

Does this tool transmit my HAR file to any server?
No. The entire JSON parsing, waterfall calculation, and redaction logic run 100% locally on your device.
