Ostranauts Mods — Steam Workshop and Nexus at 1.0
✔ Last checked: 2026-08-04
Ostranauts got official Steam Workshop support in June 2026, and 1.0 launched with 68+ mods already on the Workshop — after years of Nexus-only, folder-copying modding. Here’s the current landscape.
Where mods live now
| Platform | Status | Best for |
|---|---|---|
| Steam Workshop | Official since v0.15.1.0 (June 12, 2026) | One-click subscribe, auto-updates |
| Nexus Mods | The long-running community home | Older catalog, manual installs, some mods not on Workshop |
The game’s data lives in readable JSON, which is why the modding scene punches above the game’s size — ships, items and even game rules are moddable. The official wiki documents modding basics, and the Steam Modding forum is active.
Notable community picks
Two Nexus staples kept updated through 2026 (confirm each page’s 1.0 compatibility before installing):
- Quality of Life Fixes — expands container handling on selling lists, auto-expands the sell list, and shows item/floor/wall wear at a glance. The “why isn’t this vanilla” package.
- Ostranauts Performance Optimizer (SaveForce) — targets the game’s known pain points: load times and periodic micro-freezes on long-running saves.
We list these as community-reported quality signals, not endorsements — read recent comments before adding anything to a save you love.
The 1.0 compatibility reality
A version jump like 1.0 is exactly when mod jank peaks:
- Check the mod’s last update date against the patch timeline. Pre-April-2026 mods predate ship combat, fires and mining entirely.
- Add mods one at a time to an expendable save first. Ostranauts saves accumulate a lot of state, and untangling a broken modded save is miserable.
- Bug-report vanilla-only. If you hit a crash, reproduce it unmodded before reporting — standard courtesy that keeps dev time on real bugs. Speaking of which: known errors and fixes.
Fresh 1.0 features like bounties and the Ceres Affair ending are new modding surface — expect the Workshop count to climb well past 68. What else changed at 1.0? Full rundown here.
FAQ
Does Ostranauts have Steam Workshop support?
Yes — Workshop support shipped in v0.15.1.0 (June 12, 2026), and the 1.0 announcement counted over 68 community mods already available at launch.
How do I install Ostranauts mods?
Workshop mods: subscribe on the Workshop page and Steam handles the download. Nexus mods: follow each mod page's manual install instructions — layouts vary by mod.
Will Early Access mods break in 1.0?
Assume yes until a mod's page says it's updated. Mods built for 0.14.x and earlier predate ship combat, mining and Workshop itself — check the last-updated date before trusting one.
What mods should I try first?
Community favorites on Nexus include Quality of Life Fixes (selling-list and wear-display improvements) and the SaveForce performance optimizer (faster loads, fewer micro-freezes). Both were maintained through 2026 — verify current 1.0 status on their pages.
