Furnarchy is a pluggable, scriptable, skinnable extension program for Furcadia. While it is generally referred to as a proxy, it functions by embedding itself into Furcadia's game client, rather than intercepting the client-server's network connection. This allows Furnarchy to modify Furcadia's code and behaviour to a much greater extent than traditional proxies such as DogProxy. However, it also means that event game client update must be matched by an updated to Furnarchy itself. Furnarchy may be used in tandem with a traditional network proxy.
