About this app

This is a professional-grade HTTP packet capture and network debugging tool for mobile developers and testers, providing comprehensive real-time network traffic monitoring, analysis, and debugging capabilities for Android apps.

### Core Capabilities
- **Real-time Packet Capture**: Supports real-time HTTP/HTTPS packet capture and fine-grained packet viewing (request headers/body, response headers/body).
- **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.
- **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/HTTPS 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; no user privacy data is collected.
- **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
- Online problem tracking, weak network and exception handling verification
- Third-party SDK/embedded WebView network behavior analysis
- Rapidly construct and verify mock scenarios

Ratings and reviews

When i activate this app though the internet will stop working and i cant use any app since packets are supposed to be online. 3/10 i like the uis tho its a shame.

Fast response from developer, when having problem! 👍

Maybe I've done something wrong. SSL handshake fail on https. Certificate already installed. I've no ideas what else to do.
