Online HAR File Viewer & Analyzer

Our HAR file viewer is a powerful online tool designed to help developers and QA engineers analyze web traffic and troubleshoot network performance. A HAR (HTTP Archive) file captures a detailed log of all web requests and responses during a browser session. This HAR analyzer provides a quick way to inspect and visualize the data within a HAR file, allowing you to easily identify issues like slow page load times, failed requests, and other network-related errors. By using this tool, you can streamline your debugging workflow and improve the efficiency of your web applications.

How to Use Our HAR Viewer

Our online HAR file reader makes it simple to analyze your network data. Follow these clear steps to begin debugging your web performance:

  1. Upload Your HAR File: Drag and drop your HAR file directly into the viewer or click the upload button to select it from your computer.

  2. Inspect Network Requests: Once uploaded, the tool displays a comprehensive list of all captured requests. You can navigate through the entries to review HTTP status codes, load times, and resource sizes.

  3. Examine Details: Click on any request entry to examine detailed information, including request and response headers, payloads, and timing breakdowns. This helps in diagnosing the root cause of network issues.
