About Multiple Tools
Cookie Monster is an open-source addon for Cookie Clicker, hosted on GitHub, that adds tools and statistics to the game. It computes a Payback Period (PP) index for buildings and upgrades, accounting for factors such as achievements and changes to cookies per second, and can color-code purchase options and compare buy-10 with buy-1 choices. It is not a cheat interface, and its helpers and information can be toggled off. The addon can be loaded through a bookmarklet or as a userscript that automatically loads with the game; to avoid conflicts, it should ideally be loaded after other content mods. The master branch is the latest production version, while development and pull requests target the dev branch. Bugs and suggestions are handled as issues in the repository.
