HAR File Viewer

Open a network log without handing your cookies to a website — waterfall, timings, the slowest requests and what failed.

A HAR file contains everything. Cookies, auth headers, form posts and API responses from that browsing session. Uploading one to a website hands over live credentials. This page reads it in your browser — nothing is sent anywhere.
