When downloading mods from Nexus Mods, you have to manually click on a download button every time a new mod is added to the queue. Since modlists supported by tools like Wabbajack and Portmod often have tens or hundreds of mods, this can be very time consuming. Nexus AutoDL is an autoclicker (a.k.a., autodownloader, bot) that helps automate this process for you. Specifically, while Nexus AutoDL is running, any time a mod or collection download page is visible on your screen, Nexus AutoDL will attempt to click the download button.
If you like Nexus AutoDL, please leave a star on GitHub to help others find it.
A Windows binary is available on the releases page. Download it and double-click on it to start Nexus AutoDL. Take a screenshot and crop (WIN+S on Windows) the item on the screen you want to click on, placing the result in a directory of your choice. Point Nexus AutoDL to this directory and press the Start button. This spawns a terminal window which you can close when you are done downloading mods. You can include multiple images in this directory.
Users on other platforms can download the source code on GitHub.
Using a bot to download from Nexus is in direct violation of their TOS:
Attempting to download files or otherwise record data offered through our services (including but not limited to the Nexus Mods website and the Nexus Mods API) in a fashion that drastically exceeds the expected average, through the use of software automation or otherwise, is prohibited without expressed permission. Users found in violation of this policy will have their account suspended.
Use this at your own risk.
