A HAR (HTTP Archive) file is a JSON-formatted log of a web browser's network requests, responses, and timings.

No. This viewer parses the HAR entirely in your browser. Nothing is sent anywhere.

Why don’t I see response bodies?

Some HAR exports omit bodies for size or privacy. If the exporter didn’t include "content.text", the body won’t appear here.

How do I create a HAR?

Use your browser DevTools: open Network tab, reproduce the issue, then right‑click → Save all as HAR with content.
