Steam Workshop is a feature of Steam that simplifies mods discovery and installation for players.

Installing a mod[edit | edit source]

  1. Find a mod on the Stellaris Steam Workshop
  2. Click "Subscribe"
  3. In the Stellaris launcher, click the "Mods" tab and check the box.

Uploading a mod[edit | edit source]

Mod upload is managed from the game launcher:

  • (Optional) Define an image banner and tags in .mod file.
  • Launch the game launcher and go to the "Mods" tab
  • Click on the "Mod tools" button and select "Upload mod" within the window that opens
  • In the menu, select the mod you wish to upload and click on "Upload"
  • After upload is finished, mod page will open inside the Steam client. Copy the URL (ex: and open in your favorite browser, as it's easier than using the Steam client integrated browser.
  • Add a description, screenshots or videos, and edit change notes.
  • Once everything looks fine, make the mod public!

Mod file before upload (MyMod.mod):


Mod file when downloaded from Workshop (mymod.mod):

archive="mod/" will contain a generated descriptor.mod which is identical to mymod.mod.

In order to update a mod, hit the "Fetch Info" button before uploading the mod.[1]

Troubleshooting[edit | edit source]

  • Manage button is always greyed out: activate Steam Cloud Synch' for Stellaris (Steam -> Settings/(Preferences on mac) -> Cloud -> Enable cloud sync), it is required to upload mods.

Limitations[edit | edit source]

The workshop has a few limitations, making it currently unsuitable for large mods:

  • Modular mods that allow selecting modules at installation steps cannot be managed
  • Maximum file size prevents large mods from using the Workshop.

Mods installed via the Steam Workshop will auto-update, so be careful about non-backward compatible changes as previous saves may become unplayable.
