## What it is
A tun2socks implementation written in Go that routes traffic from a TUN network interface through a SOCKS proxy. It can be used as a command-line tool or embedded as a library in mobile and desktop applications.

## Use cases
- route all system traffic through a SOCKS proxy
- build a VPN-like client that tunnels TUN traffic via a proxy server
- embed tun2socks into an iOS or Android proxy app
- create a custom tun2shadowsocks tool with a custom handler
- redirect UDP and TCP traffic from a virtual network interface

## When to choose
- you need a Go-based tun2socks library to embed in your own proxy client
- you want to route TUN interface traffic through a SOCKS5 proxy
- you need a cross-platform tun2socks with mobile bindings

## When to avoid
- you need the best performance and lower memory usage - the author recommends the Rust-based leaf instead
- you need an actively developed tool - the latest release is from 2021
- you want a ready-made end-user VPN application with a GUI
