Where Does Stellaris Store Mods?
Stellaris mods live in a mod folder with .mod descriptors plus Steam Workshop. Save games stay separate per the saves post.
Last updated
Save games hold campaigns while mods change the rules. Local mods live as folders with .mod descriptor files in the mod directory. Workshop items mirror in the Steam content tree.
The existing saves post covers campaign files; this one covers the mod side. Enable sets in the launcher playset before starting. Descriptor version fields decide compatibility at load.
Where Stellaris stores this, by platform
%USERPROFILE%\Documents\Paradox Interactive\Stellaris\mod
Local mods with .mod descriptors plus ugc and workshop mirrors beside them. Playsets live in launcher settings. Saves sit in the sibling save games folder.
~/Documents/Paradox Interactive/Stellaris/mod
Same Documents relative layout on Mac. Keep one playset per campaign since the launcher shares descriptors across installs.
~/.local/share/Paradox Interactive/Stellaris/mod
Identical mod layout on Linux under local share. Proton and native builds share descriptors while Workshop mirrors stay per library.
Frequently asked questions
How do I install Stellaris mods?
Subscribe on Steam Workshop and enable the set in the launcher playset. Files land in the workshop content tree plus local .mod descriptors below. Keep one playset per campaign since version mismatches break saves.
How do I back up a modded campaign?
Copy the mod folder plus the save folder from the saves post with the launcher quit. Descriptors travel as .mod files while subscriptions mirror in Workshop. Removing a gameplay mod mid campaign corrupts the timeline.
