Fortnite Autoleaker is an open source program created in python.
First install the pip packages using the console by entering the following command
pip install -r requirements.txt
To use the image merger you need to change the path on line 70 and as in the example but with your path.
PATH = r"C:/Users/rush/Desktop/AutoLeak/images"
The code is not very tidy, but it is functional, it is open source and you can change anything you want.
This tool uses Fortnite-Api
Now you can test new version of AutoLeaker in beta branch of this repo
