Packet Capture Pro is a powerful packet capture, network debugging, and traffic analysis tool designed for developers, QA engineers, API testers, and network analysts. It supports HTTP/HTTPS/WebSocket packet capture, API debugging, performance analysis, and stress testing across iOS, Windows, and macOS, helping teams efficiently complete cross-device network debugging workflows.
Features
HTTP/HTTPS/WebSocket Packet Capture
Capture HTTP, HTTPS, and WebSocket traffic through local VPN technology and inspect requests and responses in real time. Supports multiple viewer modes including Raw, Text, JSON, XML, HTML, Image, Media, HEX, and Binary. Full capture history is stored locally for convenient replay, inspection, and traffic analysis anytime.
Network Debugging & API Testing
Freely edit URLs, request parameters, headers, and request bodies to test various network scenarios with ease. Import captured requests directly to quickly test mobile app APIs, Web APIs, or third-party services. Monitor response data, status codes, and performance metrics in real time to quickly identify API request failures, abnormal responses, request timeouts, SSL issues, and network exceptions. Perfect for API debugging, HTTPS traffic analysis, mobile app testing, backend troubleshooting, network analysis, and QA testing.
Request Rewrite & Replay
Automatically modify requests or responses based on custom rules. Supports five rewrite modes: request replacement, response replacement, request modification, response modification, and redirection. Multiple rewrite rules can run simultaneously, allowing you to efficiently simulate and debug complex network behaviors.
Replay allows you to resend captured requests to reproduce issues quickly. Advanced Replay supports custom replay count, delay, and interval settings, making it ideal for API reproduction, stress testing, and performance validation.
Cross-Platform & Cross-Device Collaboration
Mirror mobile app network traffic to the PC client in real time. Quickly connect through QR code scanning or IP/Port input for debugging and analysis on a larger screen with seamless collaboration.
Data Import & Export
Import external packet capture files directly into the app for network traffic analysis.Export captured traffic data locally in HAR, CSV, and other formats for easy saving, sharing, and analysis.
Custom Capture Rules
Create flexible capture rules for precise traffic analysis.
Bypass Rules: Ignore traffic from specified domains without capturing it.
Intercept Rules: Capture only traffic from specified domains for focused HTTPS analysis.
Toolbox
Integrated developer and network debugging utilities include:
· AES Encryption & Decryption
· URL/Base64/Unicode/MD5 Encoding & Decoding
· Ping & TCP Ping Network Diagnostics
· Regular Expressions
· JSON/XML/HEX Viewers
Efficient support for packet capture, API testing, network debugging, and stress testing.
How It Works
Packet Capture Pro creates a local VPN on your device and routes all traffic through a local proxy server. Once the VPN is enabled, the app captures all Wi-Fi and cellular traffic locally, enabling complete packet inspection and network analysis directly on your device.
Sensitive Data Notice
Packet Capture Pro uses a self-signed root certificate generated locally on your device. All captured requests and response data are stored locally and are never uploaded to any server, ensuring complete privacy and security during packet capture and debugging.
