HTTP/HTTPS/WebSocket packet capture, API debug, replay, traffic analysis tool

Packet Capture Pro is a professional HTTP/HTTPS/WebSocket packet capture and network debugging tool designed for developers, QA engineers, API testers, and network analysts.It supports real-time packet capture, API debugging, traffic analysis, request replay, rewrite, and network troubleshooting, helping you quickly identify and resolve various network issues.

Supports Android, iOS, Windows, and macOS for seamless cross-platform collaboration. Android devices can perform HTTPS packet capture and traffic analysis without Root access.Whether you are working on mobile app testing, API testing, backend API integration, web debugging, or network analysis, Packet Capture Pro delivers a fast, stable, and professional packet capture and network debugging experience.

Features
● HTTP/HTTPS/WebSocket Packet Capture
Capture and analyze HTTP/HTTPS/WebSocket traffic in real time using a local VPN proxy. View detailed request and response data including request headers, response headers, status codes, request bodies, response bodies, and raw data.
Supports multiple data viewing formats including Raw, Text, Hex, JSON, XML, Images, and Videos, helping developers perform traffic analysis, HTTPS debugging, and mobile app testing more efficiently.

● Network Debugging & API Testing
Freely edit URLs, query parameters, headers, and request bodies to simulate and test various network scenarios. Easily import captured requests to quickly test mobile app APIs, Web APIs, and third-party services.
View response data, status codes, and performance metrics in real time to quickly identify API failures, abnormal responses, request timeouts, and SSL issues. Ideal for API debugging, HTTPS traffic analysis, mobile app testing, backend troubleshooting, network traffic analysis, and QA testing.

● Rewrite & Replay
Rewrite automatically modifies HTTP/HTTPS requests and responses using custom rewrite rules. Supports request replacement, response replacement, request modification, response modification, and redirection. Run multiple rewrite rules simultaneously to simulate complex network environments and significantly improve debugging efficiency.

Replay allows you to resend captured requests for issue reproduction and API debugging.
Advanced Replay supports custom replay count, replay delay, and replay interval, making it ideal for API validation, stress testing, automated debugging, and request replay scenarios.

● Cross-Platform & Cross-Device Collaboration
Project mobile network traffic to your PC for real-time analysis on a larger screen, making request inspection and network analysis easier and more efficient.
Quickly connect devices using QR codes or IP/Port pairing for seamless cross-device collaboration.

● Import & Export
Export captured traffic data in HAR and CSV formats for easy viewing, sharing, and traffic analysis.

Also supports importing external capture files for fast issue troubleshooting and network investigation.

● Toolbox
Packet Capture Pro includes a complete toolbox with built-in tools including:
- AES Encryption & Decryption 
- URL/Base64/Unicode/MD5 Encode & Decode 
- Ping & TCP Ping Network Diagnostics 
- Regular Expressions 
- Certificate Hash Conversion 
- JSON/XML/HEX Viewers 
Efficient support for packet capture, API testing, network debugging, and stress testing.

● Privacy First
All packet capture and network analysis data are processed locally on your device.

Packet Capture Pro uses locally generated self-signed certificates for HTTPS traffic analysis, ensuring that no traffic data is uploaded to external servers.

With fully localized processing, your debugging data and network traffic remain secure, private, and reliable.
