Could you build this?
Partial Building a basic web UI to configure mock endpoints is simple, but intercepting local OS and network traffic via a MITM proxy with SSL certificates requires native networking software.
What it would actually take: The product requires a local desktop proxy daemon (built with Go, Rust, or Node using tools like mitmproxy or custom HTTP/HTTPS proxy sockets) paired with dynamic SSL/TLS root certificate generation and OS proxy setting manipulation. The difficult parts are properly handling HTTP/2, WebSocket interception, mutual TLS, and seamless OS/browser CA installation across macOS, Windows, and Linux.
