Core Keeper is a charming underground mining adventure that's best played with friends on a dedicated server. With up to 8 players digging through procedurally generated caverns, fighting bosses, and building a base around the mysterious Core, a hosted server keeps your world accessible around the clock.
Why Host a Core Keeper Server
Core Keeper is lightweight and straightforward to host, making it ideal for groups who want a persistent co-op world without the complexity of managing heavier games:
- Low resource needs — 2GB RAM handles 8 players comfortably
- Small world files — Procedural caves stay compact even after extensive exploration
- Simple setup — Most hosts offer one-click Core Keeper installation
- Affordable — Plans start at $4–6/month
What to Look For
Core Keeper hosting is simple, but a few features make the experience much better:
- Automatic backups — Boss fights can go wrong, and world corruption (while rare) can happen in early access games
- Easy updates — Core Keeper gets frequent patches; your host should update the server automatically or with one click
- Low latency — Combat against bosses like Ghorm and Hive Mother is real-time and benefits from snappy connections
- File access — FTP/SFTP lets you download your world save as a backup or migrate between hosts
Performance Considerations
Core Keeper is well-optimized and rarely stresses server hardware. The main factors that affect performance:
- World age — Older worlds with extensive mining have larger save files, but the impact is minimal
- Boss fights — Multi-phase boss encounters with many projectiles create brief CPU spikes
- Player spread — When all 8 players explore different areas simultaneously, the server loads more chunks
Even in worst-case scenarios, a 2GB server handles Core Keeper without issues. Budget hosts work perfectly well for this game.
Playing with Friends
The 8-player limit keeps servers intimate. Core Keeper is designed for close cooperation — sharing resources, specializing in different skills, and coordinating boss attempts. A dedicated server means no one has to be the "host player," and everyone can jump in to tend crops or smelt ores whenever they want.
