Inspect & Forensics
Inspect a .har capture and strip auth tokens and cookies before sharing.
Runs entirely in your browser
Nothing you paste is uploaded. Monaco and Prettier load on demand from this origin.
HAR capture
Paste .har JSON or load a file — auth headers and cookies are redacted
There is no upload endpoint — your files are processed in this browser tab. Open your network tab and check. See how it stays private.
How to HAR viewer
- Open a HAR. Drop a .har file exported from your browser's dev tools.
- Inspect. Browse requests, status, timings, and headers.
- Scrub & export. Redact tokens and cookies, then save a safe copy.
HAR files are how you share a network capture with support or teammates — but they're full of auth tokens and cookies. Viewing and scrubbing one locally lets you diagnose the issue and share it without leaking credentials.
For other captured traffic, the PCAP viewer reads packet captures; to scan any text for secrets, the secret scanner.
Frequently asked questions
Why scrub a HAR before sharing?
HAR files capture full requests, including Authorization headers, cookies, and tokens — sharing a raw one can leak credentials. The scrubber removes those before you send it.
What can I inspect in a HAR?
Every captured request: URL, method, status, timing waterfall, headers, and bodies — the same data as the network tab, in a shareable file.
Is my HAR uploaded?
No. Parsing and scrubbing run in the browser, which is essential since HARs contain secrets.
