The HTTP Archive format, or HAR, is a JSON-formatted archive file format for logging of a web browser's interaction with a site. The common extension for these files is .har.

The specification for the HTTP Archive (HAR) format defines an archival format for HTTP transactions that can be used by a web browser to export detailed performance data about web pages it loads. The specification for this format is produced by the Web Performance Working Group[1] of the World Wide Web Consortium (W3C). The specification is in draft form and is a work in progress.[2]


The HAR format is supported by various software, including:[3]
