Scripting and Extensions

From Melvor Idle
This page is up to date (v0.19.2).

Many people have developed scripts and extensions that add QOL, automatication, calculators and more. There is an active community of people trying to develop new scripts and extensions on the Melvor Idle Discord.

Disclaimer: It is possible that there are bugs in these scripts that could corrupt your game. Also note that many of these scripts and extensions were created for earlier versions of the game and could not be working in newer versions, or worst case senario, corrupt your save. It is highly recommended to BACKUP YOUR SAVE before running any scripts or extensions.

Disclaimer: Do not run code you can not understand or do not trust. Malicious code could be included in any of these scripts and extensions.

In-game functions

It is possible to interact directly with the ingame functions of the game through the console. This can be used to add items, levels, GP and more.

See list of In-game Functions.

How to Use?

Depending on the type of script or extension there are different ways needed to add them to the game.


Extensions are independent add-ons that run in the browser. How to install varies from different browsers.

For Firefox, most extensions can be installed directly to the browser from the Firefox Extension Store.

For Chrome, many extensions needs to be added as an upacked extension while in Developer Mode.

Some extensions might require you to edit specific files or set specific variables before they can run. The page with the download link will usually have a more detailed explanation on how to install.

Remember to refresh the game for the extension to take effect.


Userscripts are programs that run by the help of userscript manager browser extensions such as Greasemonkey or Tampermonkey.

If the source of your userscript is a userscript repository, such as Greasyfork, simply Install by clicking the button on the page.

If the userscript is shared through a plain text sharing site, such as Pastebin, copy the code into a new userscript in your userscript manager browser extension.

Remember to refresh the game for the userscript to take effect.

Console scripts

The simplest form of scripts are javascript code that are pasted directly into the console of of your browser.

To access the console open Developer Tools (usually by pressing F12) in your browser and navigate to the console. Then, simply paste the code in the input field and press enter. Most console scripts will require you to fill out variables in the code before executing them.

Do note that unlike extensions and userscripts, console scripts will run without refreshing the game, but will in turn not be saved when the game is closed.
