Can I add mods to Cookie Clicker?

Yes — you can add mods to Cookie Clicker. The Steam release supports the Steam Workshop (subscribe to mods in the Workshop and they’ll be downloaded into the game’s /mods/workshop folder), and the game’s author documents how to publish and install mods. The browser version also accepts JavaScript add‑ons (loaded via Game.LoadMod, bookmarklets, or browser extensions), and there are community mod managers that make enabling/disabling easier. See the official Steam Workshop documentation for details. (Orteil maintains guidance for workshop/local mods.)

Modding methods and cautions you should know: - Steam Workshop: subscribe to mods inside Steam; they install to /mods/workshop automatically. See the official workshop guide. - Local or manual install: drop mod folders into the game’s mods/local folder or use Game.LoadMod/bookmarklets (common for the browser build). See the community modding guide. - Tools & popular mods: community mod managers (e.g., Cookie Clicker Mod Manager) and mods like Cookie Monster are widely used; check their pages before installing.

Always back up your save (or use cloud save), verify mod compatibility with your game version, and be cautious with mods that alter achievements or automate play, since they can break saves or the game experience.
