CookieMaster v.1.5.2 Interface

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. The last release was in March 2014, compatible with the old, no more released Cookie Clicker 1.0411. 

Update: GitHub user rashfael has an active fork of CookieMaster for versions beyond 1.0411.

How To UseEdit

Unfortunately, the original CookieMaster is no longer active. Install rashfael's active fork instead with the bookmarklet method:

  • Paste the following code into a new bookmark in your browser:
javascript:with(document)(head.appendChild(createElement('script')).src ='//'

  • Number localization: Display a period or comma as your preferred decimal separator
  • Calculate and display the most efficient purchases and upgrades
  • Display estimated time left until upgrades and buildings are affordable

I try to update CookieMaster as often as possible, but I'm currently a single developer doing this in my spare time, so there's no fixed release schedule as such. For a full release history, consult the CHANGELOG page on GitHub.

Note: These are releases for the original inactive CookieMaster.

Browser SupportEdit

Extensive browser testing has not yet been carried out, however CookieMaster should work happily in current releases of the following browsers:

  • Chrome (recommended)

CookieMaster uses some new web features that may not be supported in older browsers.
