📋 Overview

REST API Monitor is a powerful Chrome extension designed to help developers, testers, and analysts monitor, log, and analyze REST API requests made by web applications. With its intuitive interface and comprehensive features, it provides real-time insights into API communication patterns.

🎯 Perfect for Developers, QA Engineers, and API Analysts

✨ Key Features

🔍 Real-time API Monitoring

Monitor all REST API requests in real-time as they happen in your browser tabs. Track GET, POST, PUT, DELETE, PATCH requests with detailed information.

📊 Tab-based Organization

Organize API logs by individual browser tabs. Each tab maintains its own separate log history, making it easy to track API calls for specific websites or applications.

🎛️ Selective Tab Monitoring

Choose which tabs to monitor with individual checkboxes. Enable or disable API logging for specific tabs without affecting others.

🔍 Advanced Filtering

Filter API requests by HTTP method (GET, POST, PUT, DELETE, PATCH) and search by URL patterns. Focus on specific API endpoints or request types.

📝 Detailed Request Information

Capture comprehensive request details including headers, request body, response data, timestamps, and generate cURL commands for easy replication.

📤 Export Capabilities

Export filtered API logs to JSON format for further analysis, sharing with team members, or integration with other tools.

🚀 How It Works

1. Installation & Setup

Install the extension from Chrome Web Store or load it as an unpacked extension. The extension automatically starts monitoring API requests across all browser tabs.
