CookieMaster is a browser plugin for Cookie Clicker. It offers many useful features, statistics and options to help you get the most out of the game. It bears some similarity to the popular Cookie Monster plugin, while being more light-weight, faster to load, use and easier to extend. See below for a full feature list, as well as upcoming and planned features. CookieMaster is currently no more in active development.
