How it works
Check one Steam item at a time.
02
Review the item's compatibility tags, required DLC, dependencies, and latest update before using it with an existing colony.
03
A direct button appears only when Steam returns a valid public link. Otherwise, use the item-specific SteamCMD guidance locally and only for content you are authorized to access.
Quick answer
Know what this Oxygen Not Included item check covers.
Paste one individual Oxygen Not Included Workshop URL or Published File ID. WorkshopFetch can identify the item and show the delivery path Steam returns, but it cannot validate your game build, DLC set, dependency list, or colony save.
Use the item ID, not the game ID
Steam App ID 457140 identifies Oxygen Not Included, while every Workshop item has its own Published File ID in the individual sharedfiles URL.
- Copy an individual item URL rather than a Workshop search, browse, or collection page.
- Confirm that the returned title and App ID match the mod you intended to check.
- Check collections one item at a time because each entry can have different dependencies and compatibility rules.
Check game and DLC compatibility
The official Workshop labels items for the Base Game and DLC such as Spaced Out! and the Planet Packs. Those labels and the creator's current notes matter more than a successful metadata lookup.
- Review compatibility and Required DLC tags before adding an item to an existing mod list.
- Look for required libraries, other Workshop items, and load-order instructions on the official page.
- Recheck the item's update date after a game update because older mods can stop loading correctly.
Keep troubleshooting local
WorkshopFetch does not install, enable, update, or remove Oxygen Not Included mods. Steam and the game remain responsible for the subscription and local mod files.
- If a mod causes errors, follow Klei's current troubleshooting guidance and test subscribed content methodically.
- A public Steam URL does not prove that an item works with your current colony, game branch, or DLC configuration.
- SteamCMD guidance is not a bypass and may still require the access Steam expects for the item.

Oxygen Not Included FAQ
Can I check an Oxygen Not Included mod here?
Yes. Paste one individual Oxygen Not Included Workshop item URL or its numeric Published File ID.
Is App ID 457140 the Workshop item ID?
No. App ID 457140 identifies Oxygen Not Included. The Workshop item ID is the separate numeric value after id= in an individual sharedfiles URL.
Does the lookup confirm Base Game or DLC compatibility?
No. Check the official item page for Base Game, Spaced Out!, Planet Pack, and other compatibility or Required DLC tags.
Can I paste an Oxygen Not Included mod collection?
No. Collections contain several independent Workshop items. Open and check each individual item separately.
Will dependencies be downloaded automatically?
No. Review Required Items and creator instructions on Steam. WorkshopFetch checks one item and does not expand dependency chains.
What if Steam returns no direct file URL?
SteamCMD is local guidance, not a bypass. Steam or the game may require access through your own Steam account, ownership of the game, or other item-specific permissions.
