Packet Capture Pro vs ApiCatcher

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.

ApiCatcher is a user-friendly mobile HTTP/HTTPS/WS/WSS packet capture and debugging tool. ApiCatcher also offers macOS and Windows versions (ApiCatcher Desktop), and the ApiCatcher can sync captured traffic to ApiCatcher Desktop in real time. [Key Features] • Traffic Capture: Capture HTTP, HTTPS, WS, and WSS traffic (WS: WebSocket; WSS: WebSocket over TLS). • Data Manipulation: Copy, export, encrypt, and decrypt Query Params, Headers, and Bodies. • Host Filtering: Configure blacklists and whitelists to filter captured hosts. • Request Replay: Modify and resend requests. • Combo Replay: Schedule and execute multiple requests sequentially based on dependencies, with support for dynamic parameter injection. • Scheduled Replay: Automate and trigger request replays at set intervals. • Auto-Generated API Docs: Automatically generate API documentation and export directly to Postman or Apifox. • Rewrite Rules: Mock responses, redirect requests, modify requests/responses, or drop requests/responses. • Scripting Engine: Extend capabilities with script plugins to flexibly modify requests and responses on the fly. • History Export: Batch export captured traffic as HAR files. • API Scanner: Run rule-based vulnerability/error detection and statistics on captured traffic, with support for custom scanning rules. • Media Export: Batch export images and videos, with automatic merging for segmented download requests. • Real-Time Sync: Stream captured HTTP/HTTPS traffic instantly to ApiCatcher Desktop for advanced analysis and debugging. It also supports syncing to Burp Suite, which requires installing the plugin provided by ApiCatcher on Burp Suite. • DNS mapping/spoofing: Bypass DNS resolution by sending requests for specified domain names to a designated IP address, achieving an effect similar to editing the hosts file on a computer. • Support decoding request/response bodies encoded with the Protobuf protocol, such as gRPC requests. If a .desc descriptor file is provided, field names can also be decoded. [Personalization Settings] • Configurable code highlighting styles with multiple built-in themes, supporting JSON/XML/HTML/JS. • AI assistant mode available: directly capture and analyze packets through AI dialogue. [How It Works] ApiCatcher establishes a local VPN connection on your device to route all network traffic through a local Man-in-the-Middle (MITM) service. As long as the VPN is active, ApiCatcher can capture any HTTP/HTTPS/WS/WSS traffic passing through Wi-Fi or cellular data. [Data Privacy & Security] ApiCatcher's root certificate is a self-signed certificate generated entirely on your own device. All captured HTTP/HTTPS/WS/WSS data is stored locally on your device and is never uploaded to any remote servers.
