## What it is
ShadowsocksX-NG is a macOS GUI client for the Shadowsocks proxy protocol, rewritten in Swift with ss-local running as a background Launch Agent. It supports SIP003 plugins (kcptun, simple-obfs, v2ray-plugin), AEAD ciphers, PAC/GFW List updates, and server profile sharing via QR codes or URLs.

## Use cases
- bypass internet censorship on macOS with a shadowsocks proxy
- set up a SOCKS5 proxy client on my Mac
- share proxy server profiles via QR code
- use v2ray-plugin or kcptun with shadowsocks
- configure PAC-based proxy rules with GFW List
- route specific apps through a proxy with custom PAC rules

## When to choose
- you need a native macOS shadowsocks client with a GUI
- you want plugin support like v2ray-plugin, kcptun, or simple-obfs
- you need QR code import/export of server profiles
- you want PAC-based system proxy configuration with custom rules

## When to avoid
- you need a client for Windows, Linux, iOS, or Android
- you want a headless/CLI-only proxy client
- you need protocols beyond shadowsocks such as WireGuard or OpenVPN
- you require frequent updates - the project is in maintenance mode
