Packet Capture Pro vs Tracer

Packet Capture Pro is a professional network analysis, packet capture, HTTP proxy, and API testing tool for iPhone and Mac. Built for developers, QA engineers, API testers, and cybersecurity professionals, it helps you capture, inspect, intercept, and debug HTTP, HTTPS, and WebSocket traffic. Debug APIs, analyze app traffic, monitor networks, and automate testing with rewrite rules, request replay, and JavaScript scripts. Core features HTTP/HTTPS/WebSocket Packet Capture Capture and inspect network traffic in real time using a secure local VPN proxy. ● Capture HTTP, HTTPS, and WebSocket requests ● View requests, responses, cookies, headers, and payloads ● Multiple data viewers: Raw, Text, JSON, XML, HTML, Image, Media, and HEX ● Store capture history locally for offline analysis and replay Perfect for packet analysis, traffic inspection, API debugging, and network monitoring. Advanced API Testing & Request Debugging Powerful tools for API development and troubleshooting. ● Edit URLs, query parameters, headers, and request bodies ● Import captured requests for rapid API testing ● Monitor response times, status codes, and performance metrics ● Diagnose API failures, SSL issues, timeout errors, and network exceptions Ideal for REST API testing, mobile app debugging, and backend service validation. Rewrite Modify requests and responses dynamically with flexible rewrite rules. Supported Rewrite Modes: ● Request Replacement ● Response Replacement ● Request Modification ● Response Modification ● URL Redirection Automate testing workflows and simulate real-world network scenarios without changing application code. JavaScript scripts Automate API testing and network debugging with JavaScript. ● Modify HTTP/HTTPS requests and responses ● Process URLs, headers, bodies, JSON, text, and binary data ● Redirect requests and import or export scripts Advanced Replay Replay captured requests with configurable loops, delays, and intervals. ● API reproduction and debugging ● Performance validation ● Stress testing and load simulation ● Regression testing workflows Cross-Device Packet Capture & Network Debugging Capture network traffic on mobile and analyze it efficiently on desktop. Inspect requests, debug APIs, and troubleshoot issues on a larger screen. ● Sync mobile packet capture data to your computer in real time ● Connect devices quickly by scanning a QR code or entering connection details ● Inspect HTTP, HTTPS, and WebSocket requests and responses in real time ● Search, filter, and analyze network traffic Import / Export Work efficiently with industry-standard traffic formats. ● Import HAR files for packet analysis ● Export captured sessions as HAR or CSV ● Share debugging sessions with teammates ● Archive traffic data for future investigation. Precision Capture Rules Filter traffic intelligently and focus on what matters. ● Exclude specific domains from packet capture ● Capture HTTPS traffic only from selected domains Reduce noise and improve debugging efficiency. Developer Network Toolbox Everything you need for everyday network diagnostics. ● AES Encryption & Decryption ● URL Encoding & Decoding ● Base64 Encoding & Decoding ● Unicode Conversion ● MD5 Hash Generation ● Ping & TCP Ping Diagnostics ● Regular Expression Tester ● JSON Viewer / XML Viewer / HEX Viewer Privacy First Packet Capture Pro uses a local VPN configuration to capture and analyze network traffic securely on your device. ● No cloud uploads ● No data collection ● No third-party servers ● All captured traffic remains on your device Your requests, responses, API data, and packet capture history are stored locally, ensuring maximum privacy and security.
