About Jakcodex/Muledump

A fork of the original Muledump by Atomizer, Jakcodex/Muledump was originally created to address the broken state original Muledump had found itself in. It is fully compliant with Deca rate limiting, has an in-browser installation manager, and includes many new features.

Check out the Github page to read more about Jakcodex/Muledump.


A browser extension is presently required to enable your browser to communicate with Deca servers. This guide assumes you are using Chrome. You can read more about this and other browsers at the Requirements page.

Step 1 - Install Extension

You must install the Allow-Control-Allow-Origin: * extension first.

Step 2 - Configure Extension

Once installed a “CORS” icon will show up in the upper right corner of your browser.

Open the CORS menu and remove the default Intercepted URLs list. Then add:*

It should look like this:

Failure to properly configure the CORS extension can cause issues browsing other websites.

Step 3 - That’s it!

Just be aware that sometimes the CORS extension needs you to switch it off and back on again to start working.

Hopefully in the future Deca will allow cross-origin requests to Appspot removing the need for this extension :)

Account Setup

Jakcodex/Muledump is built with SetupTools to assist you in managing and configuring Muledump.

There is no need to edit an accounts.js file. All data is stored in your browser’s local storage.

Step 1 - Introduction

If you’re not already familiar with Muledump or SetupTools, check out the Overview and Introduction links. If you’re been following this guide properly you can skip over Requirements here.

This guide assumes you are a new user who has never used Muledump before. Go ahead and follow the New User link.

If you are an existing Muledump user with an accounts.js file you can follow the Accounts.js Import link.

If you are a Steam user and need your credentials, check out the Steam Users Setup Guide.

Step 2 - Accounts.js Import

This step is entirely optional.

The use of an accounts.js file is no longer required in Jakcodex/Muledump.

If you don’t know what an accounts.js file is or do not have one, just skip this step and head over to Step 3.

To upload an accounts.js file, click “Choose File” and select your accounts.js file.

If you need to use manual mode, then paste the file contents into the text box.

Muledump Local users with an accounts.js file in their Muledump folder can click “setup” and quickly run thru accounts.js import.

Step 3 - Accounts Manager

Add and review all of your accounts and click Save Accounts.

Step 4 - Create a Backup

Jakcodex/Muledump includes a backup management system keeping backups of your Muledump configuration.

It is recommended you create and download a backup so you can quickly restore your Muledump experience at a later date.

Save it somewhere safe and secure. It contains all your account usernames and passwords.

Automatic and manual backups are stored in your browser’s local storage; however, they can accidentally be deleted.

Step 5 - Reload

Refresh the page and you’re all set!


If you have problems connecting to your account, the CORS Assistant will attempt to help you resolve the problem.
