Need more than 6 GB? We’ll build you a custom server →
Lag-free, even under attack.
Game servers are DDoS magnets: a rival server, a banned player or a bored kid can flood yours. Every Nxeon game server sits behind the Nxeon Shield, so attack traffic is scrubbed before it ever reaches your world.
Diagram: traffic from the internet passes through Cloudflare, AWS Shield, Azure DDoS Protection, OVHcloud VAC and NX Sentinel. Attack traffic is removed at each layer, and only clean traffic reaches your isolated server.

Global Anycast EdgeCloudflare · L3 · L4 · L7Floods are absorbed across a planet-scale anycast network, hundreds of cities deep, long before they reach our regions.

Hyperscale Flood AbsorptionAWS Shield · L3 · L4Elastic hyperscale capacity soaks up SYN floods, UDP reflection and amplification attacks at the network layer.

Our in-house engine fingerprints every flow, applies zero-trust packet inspection and adaptive rate-shaping, and self-tunes firewall rules the moment attack patterns shift.

The questions people ask right before they start.
Is there a player limit?
No player cap from us — Core Keeper officially supports 8. Every plan's player number is only a recommendation for smooth performance on that plan's memory and CPU; you set your server's own max players in Settings.
Which size do I need?
Core Keeper comes in 3 sizes: 2 GB (recommended for about 8 players) at $4.99 a month (first term, then $7.18), 4 GB (recommended for about 8 players) at $7.99 a month (first term, then $11.50) and 6 GB (recommended for about 8 players) at $11.99 a month (first term, then $17.26). The picker above recommends one for your player count and mods, and you can resize later.
Will my server lag?
Your server runs on NVMe hardware, and the size picker recommends enough memory for your players and mods. If you grow, resize from the panel in a click.
What happens if my server gets attacked?
Every game server sits behind the Nxeon Shield: five layers of DDoS filtering that scrub attack traffic before it reaches your world.
Are my worlds backed up?
Switch on scheduled backups in your server’s panel and it keeps the last 2 daily restore points, ready to roll back to.
Can I install mods and plugins?
Yes. Add supported mods from NxLabs to your server in one click, or upload your own files.
Can I change size later?
Yes. Resize from the panel whenever your community is ready.
Where are the servers?
Core Keeper servers run in Singapore, Germany and Canada. Pick the region closest to most of your players when you deploy.
Do you offer custom servers for big communities?
Yes. If you need more than 6 GB, a network of linked servers or dedicated hardware, talk to us and we’ll size and quote a custom setup.
Can I cancel anytime?
Yes. There’s no lock-in.
Your world is waiting.
