## What it is
ShadowsocksR is a Windows proxy client written in C# that tunnels traffic through ShadowsocksR servers via a local SOCKS5/HTTP proxy with system proxy and PAC support. It is a fork of the original Shadowsocks Windows client by clowwindy.

## Use cases
- bypass internet censorship with a shadowsocks proxy on windows
- route browser traffic through a socks5 proxy at 127.0.0.1:1080
- configure PAC rules and update them from GFWList
- manage multiple shadowsocks servers from the system tray
- tunnel arbitrary applications' UDP traffic through a proxy

## When to choose
- you need a Windows GUI client for the ShadowsocksR protocol specifically
- you want system proxy and PAC-based routing on Windows 7/8+

## When to avoid
- you need a maintained or actively patched client - the project is abandoned since 2019
- you use modern Shadowsocks (non-R) servers or platforms other than Windows
- you need official support for UDP proxying without third-party tools

## Facets
- artifact type: application
- maturity: abandoned
- function: proxy, networking, security, privacy
- domain: privacy, censorship-circumvention, networking, windows
- platform: windows, dotnet
