How do I get a HAR file?
Open your browser’s developer tools and select Network. Reproduce the slow or broken flow, then export the recording as HAR. In Chrome, use its sanitized export by default. Chrome’s HAR export guide explains the options.
What can this report tell me?
It shows recorded HTTP errors and request timings, including logged-in flows. A slow request is a clue, not a root-cause diagnosis. No HTTP status can mean a cancelled, blocked, failed, or incomplete request. The recording span is not page-load time. CPU work, rendering, and unrecorded activity are not measured.
Is my HAR safe to share?
Do not assume so. HAR files may contain credentials, cookies, query values, and request bodies. IndieHAR reads the complete file locally and omits headers and bodies from the report. It does not sanitize or export a safe copy. Even visible URL paths may be sensitive. Clear the file when finished. Cookieless DataFast measures page visits without receiving the file or its contents.
What does free mean here?
No account, card, premium plan, or upgrade nag. The core stays free. The file and request limits keep local processing manageable.
