    Core Keeper server hosting that keeps digging

    In Core Keeper the world only moves while a server is running. Crops wait to grow, drills stand still and conveyor belts stop the moment the host closes the game. A dedicated Core Keeper server changes that: the underground stays awake, and every member of your group can log in at any time without waiting for the host.

    Your server is ready within 60 seconds after payment. Core Keeper needs just 2 GB of RAM, so it runs on every plan we sell, from $1.90 USD a month, with unlimited slots, full sFTP access, backups and DDoS protection included.

    Joining with a Game ID

    Core Keeper does not need players to type an IP address. When the dedicated server starts, it creates a Game ID, a long code you share with your friends. They open Join Game, paste the code and connect, and Steam handles the rest.

    Where to find your Game ID

    The server shows the Game ID in the console when it starts and saves it in a text file next to the server files. Open it in our file manager and copy it to your group chat. Keep it private if you only want friends on the server.

    Bring your world from your PC

    Started a world in single player or co-op? Stop the server, upload your world file over sFTP and point the server to it. Take a backup of both sides first.

    World settings and Core Keeper mods

    A Core Keeper dedicated server reads its main settings at launch: the world name or slot, the seed, the world mode and the player limit. Change them when you create a new world, then keep that world running for as long as your group plays it.

    • Pick the world mode that suits your group, from a relaxed run to a harder one.
    • Use a fixed seed to replay a world you liked.
    • Core Keeper supports mods through mod.io; players and server need the same ones.

    Need a change of scenery after the final boss? The Game Changer switches the plan to Terraria, Starbound or another game it runs. Back up your world first.

    How much RAM does a Core Keeper server need?

    Core Keeper needs at least 2 GB of RAM on our servers, so all 9 plans run it, starting at 2 GB for $1.90 USD a month. How much more you want depends on how far your world has grown:

    • A new world for a small group is happy on the smallest plans.
    • Big explored maps with long automation lines use more memory.
    • Larger groups and mods add load, so give them a step up.

    We do not cap slots, so RAM is your real ceiling. Not sure? Our support team will help you choose.

    Hardware we own, in Dallas and Amsterdam

    Your caves run on machines we own and manage ourselves, not on rented servers. Every plan uses AMD 9950X/7950X3D processors up to 5.7Ghz, DDR5 RAM and Samsung NVMe storage, which keeps large automated bases and frequent world saves smooth.

    There are two locations to choose from, Dallas, TX (United States) and Amsterdam (Netherlands), each with a 10 Gbps network, advanced cooling, UPS backup power and DDoS protection.

    Core Keeper server questions

    Can't find your answer? Ask our support team.

    How fast will my Core Keeper server be ready?

    Your server is ready within 60 seconds after payment. We email you the access details so you can start it from the panel at once.

    How much RAM does a Core Keeper server need?

    Core Keeper needs at least 2 GB of RAM on our servers, so every plan runs it, from $1.90 USD a month. Big explored worlds, heavy automation, more players and mods use more memory.

    How do my friends join my Core Keeper server?

    With the Game ID. The server creates it at startup, shows it in the console and saves it in a text file. Friends open Join Game in Core Keeper, paste the ID and connect.

    Do I need to forward ports?

    No. The server runs in our data center, and players connect with the Game ID, so nobody has to change router settings at home.

    Can I upload my existing world?

    Yes. Stop the server, upload your world file over sFTP or through the file manager and set the server to load it. Back up both copies first.

    Can I use mods on my Core Keeper server?

    Core Keeper supports mods through mod.io. Server and players need the same mods. Make a backup before adding them, and our support team can help if the server will not start.

    Can I change to another game later?

    Yes. Open the Game Changer and pick another game your plan runs, such as Terraria or Starbound. There is nothing new to buy. Back up first.

    Where are Core Keeper servers hosted?

    In Dallas, TX (United States) and Amsterdam (Netherlands), both on hardware we own: AMD 9950X/7950X3D CPUs, DDR5 RAM, Samsung NVMe storage and a 10 Gbps network.
