Privacy details

HAR file analyzer processes your input in this browser. Inputs and results are excluded from analytics. Recent tools save tool names, visit counts and last-visit times. Saved tools store only their names. Draft saving is optional and stays on this device; delete saved text with the draft controls. Loading text from a URL is optional and contacts that server; its URL and your IP address are visible to the server. An optional “Use in” action keeps a handoff in this tab. The next tool removes it on arrival and ignores it if more than a minute has passed.

Copy link includes the inputs you choose to share in the address. Anyone with that link can reopen them. Files and generated results are excluded. Password and key tools share settings only.

Links include your inputs and settings. Anyone with the link can see them, so leave out private text. Files and generated results are left out; random draws run again.

HAR file analyzer explained

Inspect a saved HTTP Archive without replaying its requests. The summary counts requests, errors and known response body sizes, and orders requests by elapsed time. Query strings, cookies and headers are left out of the export.

Next: HTTP status codes

Next: OpenAPI explorer

A worked example

A recorded request taking 35 milliseconds appears in the timing list as 35. Two overlapping requests are added in total request time, so that sum is not a page-load measurement.

Before you use the result

HAR data is supplied by you and may be incomplete. A body size of -1 is unknown, not zero. This tool does not execute URLs, diagnose network causes or sanitize every possible secret embedded in a path.
