I got the game with the Bundle for Racial Justice and Equality, so I don't have the steam key. Is it possible to download mods without the steam workshop?

Doesn't look like it, which is kinda lame considering it's the main reason I even bought the bundle.

There's also this tool which I don't know much about, and is certainly not supported by steam or itch so use at your own risk, but it does appear to work if you search for a mod and input the id# of the mod https://steamworkshopdownloader.io/

(the id# is in the link to the mod if you click on them here https://steamcommunity.com/app/224480/workshop/  

just put the mods in the workshop folder in the game's directory (they can stay in the zip)

Yes There Is. 

1. Go To The Workshop Of Octodad And Choose Any Mod Then Copy It's Link.

2. Go To This Link : http://steamworkshop.download/

3. Right Click On Octodad Then Click On Open File Location

4. Right Click On  Octodad Editor Then  Click On Run As Adminstrator

5. It Opens. Now We're Gonna Paste The Link In Steamworkshop.download And Then Press Download And Press
Download : (Insert Mod Name Here)
Now You'll Need 7zip To Extract It Or Winzip

6. After You Extracted It Put It On Desktop Then Go To File On The Top Left Of Octodad Editor Then Press Open Then Press Level / GUI
And Go To Desktop Then Your Mod Then On That File Find The .irr File Inside The Extracted File


Done!
