Packet Capture Pro vs Busymate DevTools

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.

Busymate DevTools is a network debugging tool for developers. It captures the HTTP and HTTPS requests made on your device, so you can inspect headers, bodies, status codes, and timing while you build and debug your own apps and websites. It works like a desktop web-debugging proxy, but runs entirely on your iPhone or iPad — no Mac and no Wi-Fi proxy configuration required. WHAT IT DOES • Captures DNS and TCP traffic system-wide using Apple's NetworkExtension (a local, on-device VPN tunnel — nothing is routed through our servers). • Decrypts HTTPS only for the specific domains you add to the SSL-proxy list. Everything else stays end-to-end encrypted and is passed through untouched. • Shows every request/response pair in a real-time feed: method, URL, status, headers, query, and body. • Optionally syncs captures to your private Busymate dashboard at dash.busymate.dev so you can inspect them on a bigger screen, search, tag, and export to HAR. ADVANCED • Traffic rules — block, mock, or rewrite requests and responses that match your own rules, so you can test how your app handles errors, edge cases, and slow or missing responses. • Upstream proxy — optionally route a device's outbound traffic through an external proxy you have configured. • Deep links — open the app straight to a device or a request from a link. YOU ARE IN CONTROL • Capture never starts until you explicitly turn it on and accept the on-screen disclosure. • HTTPS is only ever decrypted for domains you choose. Add and remove them at any time. • Decryption requires installing and trusting a root certificate, used only to decrypt your own HTTPS traffic for the domains you choose — guided step-by-step inside the app. • You can stop capturing and remove the VPN profile from iOS Settings at any time. PRIVACY Busymate DevTools is built for inspecting traffic from apps and sites you own or are authorized to debug. Captured data can include sensitive values such as tokens and credentials, so only inspect domains you understand and control. Synced captures are stored under your own account and can be deleted at any time. See our privacy policy at busymate.dev/privacy. REQUIREMENTS • iOS / iPadOS 16.0 or later. • A free Busymate account (sign in with Apple or email) to pair the device and, optionally, sync captures to the dashboard. Busymate DevTools is intended for developers, QA engineers, and security testers working on their own software. It is not a tool for intercepting other people's traffic.
