ByteSniffer vs FlowSpy

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.

FlowSpy is an AI-powered network debugging tool for developers, QA engineers, and security researchers. Capture, inspect, filter, replay, analyze, and export HTTP/HTTPS traffic directly on iPhone and iPad. [LOCAL VPN CAPTURE] FlowSpy uses a local VPN and on-device proxy to capture HTTP/HTTPS traffic. The VPN is only used for local network debugging. It does not provide remote VPN service, anonymization, censorship circumvention, network acceleration, or remote traffic forwarding. [HTTPS INSPECTION AND CERTIFICATE GUIDE] To inspect HTTPS payloads, users must explicitly install and trust a self-signed CA certificate generated locally on the device. FlowSpy provides guided setup steps, and users can stop capture, remove the VPN configuration, or clear certificates at any time. [AI ANALYSIS] Local rule analysis is available by default and does not upload data. Pro cloud AI analysis only runs when the user explicitly starts analysis for selected traffic. It helps identify anomalous requests, performance issues, security risks, and suggested fixes. [DEVELOPER WORKFLOW] • Browse requests grouped by domain • Filter by method, status code, host, protocol, and content type • Inspect headers, body, cookies, timing, and response payloads • Replay requests and edit parameters before replaying • Export HAR, JSON, CSV, and cURL • Scan token, cookie, and privacy-field risks [PRIVACY FIRST] Captured traffic is stored locally on the device by default. FlowSpy does not include advertising SDKs and does not track users across apps or websites. Use packet capture and HTTPS inspection only on devices, apps, websites, and networks you are authorized to inspect.
