Can I host a private Core Keeper server?

Yes - every Core Keeper server we host can be set to private with a password, friends-only, or whitelist mode. The shared-world id is the connection mechanism; you control who knows it.

How many players can a Core Keeper server hold?

The dedicated server defaults to 8 players, which is the size Core Keeper is balanced around, but the limit is configurable and we sell above it. Plan S gives you those 8 slots, Plan M 16, and Plan L 30. Larger worlds ask more of the server, so the bigger plans also carry more RAM.

Can I upload my existing Core Keeper world?

Yes. Upload your local Core Keeper world folder via the FTP panel. The world becomes the canonical save once the server starts. We support migration from solo, from another host, or from Game Pass.

Where are Core Keeper servers located?

We run Core Keeper servers in 4 regions: US West, Toronto, Paris, and Sydney. You can change region at any time via My Account; the world transfers with you.

Do you offer Core Keeper backups and restores?

Yes. Automatic snapshots every 6 hours plus on-demand backups before risky changes. One-click restore from any of the last 14 snapshots. Free backups, no quota limits.

What is the average Core Keeper server hosting cost?

Pricing follows player slots and storage; Core Keeper is lightweight enough that Plan S works for most parties.

Can I upgrade my Core Keeper plan later?

Yes. In My Account → Subscriptions, you can upgrade to a higher tier with the same billing cadence. Upgrades are in-place - quota update + restart, world preserved.

FAQ

Yes. Set a password or whitelist players in the control panel.

Yes. We run automatic snapshots and provide on-demand backups for quick restores.

Pricing follows player slots, mods, world size, storage I/O, and bandwidth.

Yes. In My Account → Subscriptions, you can upgrade to a higher tier of the same game with the same billing cadence (for example, monthly to monthly). Downgrades are not available right now. During an upgrade, your deployment is updated in place (quota update + restart), not wiped and recreated.

No. Core Keeper's supported dedicated-server flow uses the Steam Tools app and a Game ID: players enter the ID to join, and the official launch guidance has no port-forwarding requirement. Your Supercraft server is reachable that way from day one.

Yes. 1.3 Riders of the Underground released on 21 September 2026 and is available on Supercraft. One change from the 1.3.0.1 patch notes worth knowing: a player who disconnects and rejoins keeps the health their client last saw, even if it changed on the server, so a health mismatch after a reconnect is expected rather than a fault.
