SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Analyzing HAR (HTTP Archive) files to quickly identify and debug network problems across requests, responses, headers, cookies, and API calls.

Core Features & Use Cases

  • HAR parsing: Extracts request/response data, headers, and cookies from HAR files for inspection.
  • Targeted debugging: Filter by URL patterns, status codes, or content types to focus on failing or suspicious traffic.
  • Insightful outputs: Generate summaries and optional JSON views to compare API calls and diagnose issues in production or testing. Use Case: When a web app experiences slow API calls, feed the HAR file to quickly locate slow endpoints and problematic headers.

Quick Start

Provide a HAR file to analyze and debug network traffic.

FAQPage Schema
How do I debug network issues from a HAR file?▼

To debug network issues from a HAR file, you provide the HTTP Archive data for parsing. The tool extracts request and response details, enabling targeted inspection of failing or suspicious traffic across multiple requests.

Can I filter HAR data by URL patterns and status codes?▼

You can filter HAR data by URL patterns, status codes, or content types to focus on failing traffic. This targeted debugging isolates problematic headers and API calls efficiently.

How do I inspect HTTP headers and cookies to diagnose API call issues?▼

You inspect HTTP headers and cookies by parsing the HAR file with this tool. It extracts and presents these network request details for targeted investigation and API issue diagnosis.

What is the best way to locate slow API endpoints in production?▼

The best way to locate slow API endpoints is to feed your HAR file to this analyzer. It parses network traffic and generates summaries to quickly identify problematic requests and slow responses.

How can I compare API calls and view results from a HAR file?▼

You can compare API calls and view results using the generated summaries and optional JSON views. These outputs help diagnose issues by presenting parsed network traffic data clearly.

Do I need a specific environment to analyze HTTP Archive files?▼

No specific environment is required to analyze HTTP Archive files. You simply provide the HAR data, and the tool parses the network requests, headers, and cookies directly for inspection.
