🚀 About

Network Spy is a cross-platform Network Proxy and Traffic Analyzer built with Tauri, Rust, and React. It intercepts, decrypts, and analyzes your application's network traffic with a stunning, high-performance interface.

Our goal is to move beyond simple "packet capturing" and provide a tool that truly understands the data being sent across the wire.

⚙️ How it Works

Network Spy operates as a Man-in-the-Middle (MITM) proxy. It sits between your application and the internet, intercepting traffic to provide deep visibility.

1. Proxy Interception: The app starts a high-performance Rust-based proxy server on your local machine.
2. HTTPS Decryption: By installing the optional Network Spy Root CA, the app can securely decrypt HTTPS traffic using industry-standard certificate pinning bypass techniques.
3. Capture & Analyze: Traffic is captured in real-time and passed through our specialized Superpower Viewers for automated decoding of GraphQL, LLM streams, Protobuf, and more.
4. Local Forever: All data is analyzed and stored locally in a high-speed SQLite database. No traffic ever leaves your machine.
