Generate .HAR File

Purpose of HAR Files

A HAR (HTTP Archive) file logs a browser's interaction with a site. HAR files are useful for troubleshooting issues like:

• Performance Problems: Slow page load or timeouts.

• Page Rendering Issues: Incorrect formatting or missing information.

These logs provide insight for first-line troubleshooting, allowing support teams to diagnose and resolve issues more efficiently.

See how HAR files are generated depending on your browser variant.
