Frequently asked questions
How much RAM does a Core Keeper server need?
Core Keeper technically runs from as little as 2-6 GB RAM (community reference values depending on player count) — with us you start at a minimum of 8 GB RAM, leaving enough headroom for more players and system overhead. For 20+ players or large explored worlds we recommend 12-16 GB.
How many players can join a Core Keeper server?
Core Keeper's server config allows up to 100 players (maxNumberPlayers, range 1-100). The game itself is officially designed for 8-player co-op (Steam: "1-8 players" / "2-8 player drop-in/drop-out online co-op") — larger communities commonly run up to around 30 players (G-Portal reference: max. 30 slots).
Is the world automatically saved?
Yes, Core Keeper saves the world automatically and continuously. Your progress — explored areas, built structures, mined resources — is fully preserved even after a server restart.
Can I use a custom world ID or seed?
Yes, via the WORLD_INDEX and WORLD_SEED variables you can specify a particular world or a fixed seed. This lets you create reproducible worlds or transfer existing worlds to your server.
How do I get started after ordering?
Your Core Keeper server is online within minutes. Configure server name, max players, and world settings in the control panel. The connection code for your friends appears in the server console after startup.
Are Core Keeper updates applied automatically?
Yes, our server checks for new Core Keeper updates on startup and installs them automatically. This keeps you always on the latest version so you and your friends can immediately discover new content like fresh biomes, bosses, and items. Manual intervention is generally not required.
Do I get my own subdomain?
Yes. Every server includes a subdomain like my-server.game-serverhosting.com, and you can change it anytime in the dashboard.
What are the free extras?
Every server can enable free add-ons such as Uptime Kuma, Sinusbot, Game Server Watcher, and more with one click in the dashboard.
How quickly is my server online?
Typical initial setup: about 3 minutes. Queues or large installations can take longer.
Is there a minimum contract term?
There is no long-term minimum. Billing is a monthly subscription and automatic renewal can be disabled. Longer terms may qualify for discounts.
Are the servers located in Germany?
Yes. All game servers run in German data centres (Falkenstein and Limburg) connected to the major German exchanges — low pings for players across Germany, Austria and Switzerland, and solid latency for the rest of Europe.
Which provider is best for my server?
The best provider is the one that shows you what you get before you pay: RAM, slots, location, price and cancellation terms. Here the price and resources are visible in the configurator before checkout, there is no minimum term and setup is automated — feel free to compare that with other offers.
Should I host the server myself or rent one?
Self-hosting costs power, time and a machine that runs around the clock; port forwarding, updates and backups are on you. A rented server is online within minutes, keeps running when your PC is off, and updates, DDoS protection and backups are included. For one or two friends on a single evening self-hosting is often fine — for a persistent world, renting pays off.
