Can I transfer my existing Core Keeper world?

Yes. Stop the server, upload your world save files into the server's save directory through the file manager or SFTP, then restart. The server loads your existing cavern rather than generating a new seed. Keep a local copy of the save until you have logged in and verified everything is present.

How do players join my server?

The server prints its game ID to the live console on startup, and players enter that ID in Core Keeper's join menu. You can also set a password in the server settings so only your crew can connect. Direct IP and port details are visible in the panel network tools.

How many players can play together?

Player slots are unlimited on our plans, so the ceiling comes from the game's own multiplayer design and your hardware. Eight players is the usual comfortable crew size for a shared cavern; larger groups should move to 3 GB or 6 GB so chunk saving keeps up with the digging.

Are backups automatic?

Yes. Every server takes automatic daily backups with ten rolling slots, and you can trigger or download one yourself from the panel at any time. Restoring is a matter of picking a slot, which is the safest way to recover from an accidental explosive mishap near your base.

About Core Keeper hosting

A Cavern That Never Goes Dark

Core Keeper's peer hosting ties the world to whoever started it, which means nobody progresses unless that person is playing. A dedicated server removes the bottleneck: your tunnels, farms, conveyor networks and boss kills are stored on the server and available whenever any crew member logs in.

It also makes long projects realistic. Somebody can spend an evening running scarlet ore back to base while the rest of the crew sleeps, and the next session starts exactly where the last one stopped, with no host handoff, no rejoining lobbies and no lost progress on the map.

Uploading And Backing Up Save Files

If your group already has a cavern going, move it here rather than starting over. Stop the server, upload the world files into the save directory using the panel file manager or an SFTP client, then start it again and confirm the map loads with your existing explored area intact.

Backups run automatically every day with ten rolling slots, and you can download any save to your own machine at any time. That combination is handy before a big update or before letting someone loose with explosives near the Core.

Server Settings And Crew Size

Core Keeper servers are configured through their settings files and startup options, where you set the world name, seed, game ID visibility and password. Everything is editable in the panel, and the live console shows the generated game ID that players paste into the join dialog.

Resource needs stay modest. Two GB at $5.00 per month is enough for a typical group, 3 GB gives extra room for an eight-player cavern with large automated farms, and 6 GB covers worlds that have been dug out for hundreds of hours. RAM is a flat $2.50 per GB.

Core Keeper hosting FAQ

Still unsure? Ask our team.

Core Keeper is one of the lighter games we host. The 2 GB plan at $5.00 per month handles a typical crew, and 3 GB at $7.50 per month gives extra headroom for an eight-player world with heavy automation. Very old, widely excavated caverns are comfortable on 6 GB.
