What is fancyss?

Fancyss is a plugin for home routers running ASUS firmware or the popular Merlin and OpenWrt alternatives. It installs directly onto the router and routes network traffic through proxy protocols to bypass the internet filtering system used in China, commonly called the Great Firewall. Because the plugin lives on the router rather than on any individual device, every device on the home network benefits automatically without needing separate software installed on each phone, computer, or tablet. The plugin supports several different proxy protocols including Shadowsocks, ShadowsocksR, V2Ray, NaiveProxy, and Trojan. It provides a management interface through the router's software center that lets users add and configure proxy servers, subscribe to server lists that update automatically, sort servers, and switch between modes such as a gaming mode and a mode for returning to China-accessible services. The exact set of features varies depending on the router's hardware architecture and the firmware variant being used. The project maintains several separate versions targeting different hardware platforms: one for Broadcom HND and AXH routers, one for Qualcomm QCA routers, one for older ARM-based Merlin firmware, and one for MIPSEL-based routers. Some of these versions are still actively maintained while others have been discontinued or placed in archive status. The README is primarily in Chinese, reflecting its main audience, and contains detailed compatibility tables showing which features are available on which platform and firmware combination.
