Network Sniffer vs ByteSniffer

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.

ByteSniffer is a professional network debugging tool designed for iOS developers, QA engineers, and networking professionals. It supports real-time capture and analysis of HTTP/HTTPS, SSE, WebSocket, TCP, and UDP traffic. You can inspect request headers, response content, real-time messages, bidirectional raw data, and data in multiple formats including Hex, Text, and JSON. ByteSniffer also provides useful tools such as Host filtering, capture history, full-text search, sharing and export, request replay, content rewriting, breakpoints, and JavaScript scripting. These features help you quickly troubleshoot API errors, connection issues, and data transmission problems. HTTPS and WSS traffic analysis requires installing and trusting the MITM certificate provided by the app. Some advanced features require Pro access. Please use ByteSniffer only with applications and network environments that you own or are authorized to test. Membership Purchase: Unlock permanent access for only CNY 19.9, including MITM, HTTPS, SSE, WebSocket, TCP, UDP, Replay, Rewrite, Breakpoints, and Scripts — for about the price of a cup of milk tea.
