Network Sniffer vs Packet Capture Pro

Network Sniffer is an intelligent network activity analyzer that helps you understand what your apps are really doing online. No technical skills required — easily identify: Which apps are secretly connecting to the internet? Are they sending requests frequently in the background? Is your privacy at risk or data being wasted? You're no longer a passive user — you're in control. Core Features (not limited to): 1. Deep Network Analysis: Visual reports showing which apps are connecting, what they are sending, how often, and whether there’s abnormal or wasteful activity. 2. Network Sniffing: Capture HTTP/HTTPS/WebSocket traffic on your iOS device, with full MITM support for encrypted traffic analysis. 3. External Proxy: Route device traffic through an external proxy server, enabling custom inspection, filtering, and debugging of network requests. 4. JavaScript Scripting: Create custom rules and behaviors using JavaScript to enhance and personalize your network inspection. 5. Request Replays: Resend captured requests to test app behavior under various conditions — ideal for debugging and performance testing. 6. Request/Response Rewrite: Modify headers and bodies of requests and responses on the fly, giving you unmatched control over data flows. 7. Client Proxy: Forward requests from other devices on your local network to this device for centralized debugging. 8. Upstream Proxy Support: Forward HTTP requests to a third-party proxy server for advanced testing or network routing scenarios. 9. Widgets & Dynamic Island Support: Monitor upload/download speeds and data usage in real time via homescreen widgets or the iPhone Dynamic Island. Permissions Network Sniffer requires VPN permission to function. This is only used for local traffic capture — no remote servers or proxying involved. Privacy Notice Network Sniffer does not upload any of your data and does not include any proxy, VPN bypass, or "scientific access" functions. Your data stays on your device.

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 Real-Time iPhone-to-Mac Traffic Sync Analyze mobile traffic on a larger screen. ● Mirror iPhone network traffic directly to Mac ● Instant connection via QR code scanning ● Manual connection through IP and Port configuration ● Real-Time packet inspection and traffic monitoring Built for seamless debugging across the Apple ecosystem. 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.
