🌟 Key Features

🔍 Proxy-Free In-App Packet Capture

• No Proxy Setup Required: Unlike traditional tools that require system-level proxy configuration, Woodpecker integrates directly within the application.
• No Certificate Installation Hassle: Bypasses HTTPS packet capture certificate trust issues, simplifying the debugging process.
• App-Level Isolation: Monitors only the target application, avoiding interference from unrelated network traffic.

📱 Multi-Platform Support

• iOS App Debugging: Deep support for monitoring network requests in iOS applications.
• macOS App Support: Perfectly compatible with macOS desktop applications.
• Android Compatibility: Supported via companion tools.

🔧 Technical Features

• Automatic Hooking of Network Frameworks: Supports mainstream libraries such as NSURLSession, NSURLConnection, and Alamofire.
• Request & Response Monitoring: Real-time display of request headers, bodies, response headers, and data.
• Data Format Parsing: Automatically identifies and displays JSON, XML, images, and other formats in a user-friendly way.
• Search & Filter: Quickly locate specific requests by URL or keyword.

💡 Developer-Friendly Features

• Request Editing & Resending: Modify parameters and re-send requests for easy API debugging.
• Custom Plugins: Extend functionality via plugins to meet personalized needs.
• Performance Monitoring: Displays key metrics like request duration and data size.
• History Records: Saves capture logs for easy review and analysis.

🎯 Core Advantages

✅ Comparison with Traditional Packet Capture Tools

Feature	Woodpecker	Traditional Tools (e.g., Charles)
Configuration Complexity	Minimal, direct integration	Complex, requires proxy and certificate setup
Target App Isolation	Precise app-level monitoring	System-level monitoring, more noise
Multi-Device Debugging	No network configuration needed	Requires same Wi-Fi and proxy settings
Certificate Issues	Completely avoided	Frequently encounters certificate trust problems

🚀 Efficiency Enhancement

• Fast Integration: Adding minimal code during development enables immediate use.
• Real-Time Debugging: View network interactions instantly while the app runs.
• Reduced Environment Dependency: No reliance on specific network environments; debug anytime, anywhere.

🛡️ Security & Privacy

• Local Data Processing: All captured data is processed locally.
• Controlled Monitoring Scope: Only monitors apps that integrate the SDK, protecting privacy.
• No External Dependencies: No data sent to external servers.
