# Free HAR Analyzer and Viewer Online

## Free HAR Viewer and Analyzer

Analyze a HAR file to inspect network timings, redirects, failed requests, and large downloads. Use the free HAR viewer without uploading your recording.

## How it works

### Open your network recording

Export a HAR file from your browser's Network panel, then select it here. You can also explore the included sample without uploading anything.

### Analyze network requests

Filter by URL, status, or resource type. Sort by duration or size, and select a request to inspect its headers and timing phases.

### Keep the evidence

Copy a request URL or download the filtered summary. Parsing and exporting happen on your device, without sending the recording to our servers.

### What is a HAR file?

HTTP Archive (HAR) is a JSON recording of network requests. It can include URLs, headers, cookies, response bodies, and timing data. Prefer a sanitized export when sharing a recording.

### Why are some values unavailable?

Not every browser records every timing or transfer size. Missing values are shown as unknown. A long waterfall bar means a longer request, not better performance. Redirect targets are linked only when they are present in the recording.

### What can this HAR analyzer diagnose?

Find slow requests, failed responses, redirect chains, and large transfers recorded in your HAR. Filtering and sorting help narrow a browser automation failure; the report does not invent missing timings or identify an unrecorded root cause.

## Take your browser workflows to the cloud.

Connect Playwright or Puppeteer to Browser Use and run your automation on managed browsers.
