Playing with my mods, me only for starters and testing

Hello,

I am now working on a new project, making the Island extensions.

I would however, start to play on it and host it on my dedicated server (for starters on my local computer so not a rented dedicated server),
using the ARK server Manager.

Play on the island, while testing the mods and update it when needed.

Is this possible or do I have to upload it to Steam first?
If so, is it possible that only I can use the mod?
I don’t want to upload mods that might be glitchy and which others can download with all the horrors that follow. :slight_smile:

Bit late but you have to upload it to test it but when you do you get the option to make it private so nobody else sees it.
