Initial paid Google Play release: full HTTP Sniffer workflow with no ads, no in-app purchases, and Pro store branding.
No-ad network sniffer: HTTP, WebSocket, gRPC, DNS, MQTT, mock, replay
HTTP Sniffer Pro is the paid Google Play edition of HTTP Sniffer. It removes advertising SDKs, in-app purchase prompts, and subscription UI while keeping the same professional network capture, mock, replay, traffic redirect, and webhook workflow. This is a professional-grade network packet capture and debugging tool for mobile developers and testers, providing comprehensive real-time traffic monitoring, multi-protocol analysis, and debugging capabilities for Android apps. ### Core Capabilities - **Multi-Protocol Capture**: Real-time capture and analysis of HTTP/HTTPS, WebSocket (WS/WSS), DNS, SSE, gRPC (Unary/Stream), and MQTT protocols. - **Analysis by Application**: Filters and analyzes network traffic by application to quickly locate the source of problems. - **HTTPS Decryption**: Provides SSL/TLS certificate management and import, and supports encrypted traffic decryption analysis. - **Traffic Redirect**: Redirect all captured TCP/UDP connections to a specified server for remote debugging and traffic inspection. - **HTTP Webhook**: Forward captured packets to custom POST endpoints for integration with external tools and monitoring systems. - **Request Simulation (Mock)**: Configurable rules allow for HTTP mocking, facilitating both online and offline debugging. - **Modify and Replay**: Supports editing requests and responses after interception, and replays to verify the effectiveness of repairs. ### Why Use VPNService Apps use Android's VPNService to implement system-level network data channels, enabling the following capabilities: - **Network Interception**: Intercepts network requests and responses from other apps on the device using VPN technology. - **Packet Analysis**: Analyze HTTP, WebSocket, gRPC, DNS, and MQTT traffic in real time, extracting and displaying key fields and data. - **Network Debugging**: Provides request path tracing, performance observation, and problem location tools to assist in development and debugging. - **Packet Rewriting**: Modifies intercepted requests, injects rules, and resends them to verify remediation solutions. ### Compliance and Transparency Statement - **User Perception**: Continuously displays the VPN service status in the notification bar to ensure users are fully informed. - **Permission Transparency**: Clearly explain the reason and purpose of VPN permissions during the authorization and onboarding process. - **Functional Necessity**: VPNService is a necessary technical means for system-level network interception and analysis. - **Security Boundary**: Used only for network debugging and analysis in development and testing scenarios. Captured traffic stays on device unless you export or share it; limited diagnostics, app/package signals, and device identifiers may be processed by Google services after consent as disclosed in the privacy policy. - **HTTPS Compliance**: HTTPS decryption is only performed after the user has actively installed a trusted certificate and explicitly authorized it. Certificate management is fully controllable and removable. ### Applicable Scenarios - Development debugging, API verification, problem reproduction and location - WebSocket/gRPC/SSE real-time communication debugging - DNS resolution analysis and MQTT IoT protocol inspection - Traffic redirect to PC for advanced debugging with Wireshark, Charles, etc. - Webhook integration for automated monitoring and alerting - Third-party SDK/embedded WebView network behavior analysis - Rapidly construct and verify mock scenarios
