Uploading a co-op save to a Stardew Valley server enables collaboration and gameplay with friends or the online community. Players can invite others to join their farm, trade resources, and collectively work towards common goals. With the server always staying online, it enriches the multiplayer experience, making it an excellent option for those seeking collaborative gameplay and interaction.

Requirement: The save must be co-op and have SMAPI installed before uploading.

Note: If the save is modded, install the mods and match configs on the server before uploading. Learn how to install mods here and learn how to edit mod settings here.
The previous host will need to create a new character.
