HAR file viewer
Inspect uploaded request timings and strip sensitive headers before export.
How to use HAR file viewer
The HAR file viewer opens a HAR file exported from browser developer tools and lists each request's method, URL, status code and time in milliseconds. It can also export a cleaned reviewed.har with authorization headers, cookies, query strings and request and response bodies removed. Logs with up to 10,000 entries are supported.
- Choose a source file. If the tool accepts multiple files, arrange them in the order you want.
- Set strip credentials and request/response bodies in export.
- Run har file viewer, review the output, then use the available copy or download controls.

Frequently asked questions
How do I remove sensitive data from a HAR file?
Keep Strip credentials and request/response bodies in export turned on. The export removes Authorization, Proxy-Authorization, Cookie and X-API-Key request headers, Set-Cookie response headers, all cookies, posted data, response body text, query strings and any username or password in URLs.
Is a stripped HAR file completely safe to share?
Not necessarily. URL paths, remaining headers and other fields can still contain personal or account data. The on-screen table also shows the original, unstripped URLs. Open the exported reviewed.har and check it before sending it to anyone.
How do I create a HAR file to view?
In your browser's developer tools, open the Network panel, reproduce the requests, then use the option to save or export all requests as HAR. Upload that file here. It must be a valid HAR log with an entries array.
