HAR viewer
Open a .har file from Chrome DevTools, Charles, Fiddler, Proxyman or Solpuga. You get a searchable request list, headers, bodies and the time per phase.
Everything runs in your browser. Nothing you type and no file you open is sent to a server.
Spec: HAR 1.2
A HAR can hold cookies, Authorization headers (for example, Authorization: Bearer eyJhbGci…), and request and response bodies. Chrome 130 and later drops cookies and Authorization unless you pick Export HAR (with sensitive data); other tools keep everything.
Don't have a .har file yet?
A HAR file is a browser's own record of every request a page made. Any Chromium or Firefox-based browser can save one.
- Open DevTools (
F12, orCmd+Option+Ion macOS) and switch to theNetworktab. - Turn on
Preserve log, so the recording survives a page reload. - Reproduce the problem.
- Right-click any request in the list and choose
Save all as HAR with content.
