## Features

- **Universal Proxying**: Transparently routes all network traffic from any application through a proxy.
- **Multi-Protocol**: Supports HTTP/SOCKS4/SOCKS5/Shadowsocks proxies with optional authentication.
- **Cross-Platform**: Runs on Linux/macOS/Windows/FreeBSD/OpenBSD with platform-specific optimizations.
- **Gateway Mode**: Acts as a Layer 3 gateway to route traffic from other devices on the same network.
- **Full IPv6 Compatibility**: Natively supports IPv6; seamlessly tunnels IPv4 over IPv6 and vice versa.
- **User-Space Networking**: Leverages the **[gVisor](https://github.com/google/gvisor)** network stack for enhanced
  performance and flexibility.
