Your Core Keeper world stays online 24/7 — unlimited slots, DDoS protection and flexible billing, live in under 60 seconds.
American ExpressAbout the game
Core Keeper is a co-op mining and crafting adventure: you wake up in a vast underground cavern, dig through biomes, farm, fish, build bases around the ancient Core and take on giant bosses together. A Core Keeper server is your crew's own dedicated server for that world — it stays online 24/7 with unlimited slots, so friends can drop in and keep digging even when the host's PC is off.
Your server, your rules: choose the world name, seed and mode — Normal, Hard, Casual or Creative — force seasonal events like Halloween, lock the world with a password and share the Game ID with your crew. If a boss run goes badly wrong, restore a Backup with ZapX Pass to bring your world back, and you can upload an existing save to continue an adventure you started alone.

FAQ
Answers to the most important questions before you start.
Price by package, term and location, never per player.
Current package prices load live from the shop in the pricing section above. Every package includes unlimited slots, so the price depends on your package (RAM, CPU), term and location, not on how many friends join. You can choose billing periods of 3, 30, 90, 180 or 365 days, and with ZapX Pass you can also buy Lifetime with a one-time payment. Rent or Lifetime explained
It depends on your world, not a fixed per-player number.
How much RAM Core Keeper uses grows with how much of the map you have explored, how big your bases are and how much automation runs at once. A small crew on a fresh world usually needs less RAM. Long-running worlds with huge explored areas and busy factories need more. Watch RAM and CPU in the panel statistics and add resources when your world needs them. As a guideline: at least 2 GB, 4 GB recommended.
Unlimited slots — no per-player pricing.
Every Core Keeper package comes with unlimited slots, so you never pay per player. The max players value in your server configuration sets how many people can be online at once, within the game's own limits. For bigger groups, what matters is having enough RAM and CPU, not a slot tier.
The free tool only runs while your own PC does.
Core Keeper's dedicated server tool on Steam is free, but it runs on your own machine. The PC has to stay on, you handle updates, network setup and uptime yourself, and you use your home connection. A hosted Core Keeper dedicated server runs 24/7 in a data center with DDoS protection, Backups and a 24/7 support chat, so your friends can play whenever they want.
Order, set up your world, share the Game ID.
Pick a package and order. Your server is set up automatically in under 60 seconds. In the panel, set the world name, mode and password, then start the server. Share the Game ID from the panel with your friends: in Core Keeper they choose Join Game and enter it to connect. How to connect to your server
Yes — upload your save and keep playing.
Yes. Upload the world files from your singleplayer game or your self-hosted server to the server's world folder, then select the matching world slot. Back up the current server world first so you can always switch back. The Help Center walks you through the exact folders and steps. Managing Core Keeper savegames
Yes — switch RAM/CPU as your world grows.
Yes. When your world grows, more friends join or the map gets heavy, you can add more RAM and CPU and keep your world as it is. If your group plays less, you can also reduce resources. Unlimited slots stay included on every package. How upgrades and downgrades work
Locations worldwide and DDoS protection on every server.
You can choose from locations worldwide. Pick the one closest to your crew for the best connection. Many North American groups start with Ashburn, Dallas or Los Angeles, and every location works well for players nearby. Every Core Keeper server runs in ZAP-Hosting's DDoS-protected network at no extra cost.
