Hytale server requirements and RAM
Hytale requires Java 25 and at least 4 GB of RAM. Size a dedicated server for view distance, loaded worlds, mods, and players exploring apart, using berrybyte's requirements calculator.
Hypixel documents Java 25 and at least 4 GB RAM for a Hytale server. Four gigabytes is a minimum, not a player-count guarantee.
Official requirements
The Hytale Server Manual lists these requirements:
| Resource | Requirement |
|---|---|
| Runtime | Java 25, 64-bit |
| Architecture | x64 or arm64 |
| Memory | At least 4 GB |
| Network | QUIC over UDP; default port 5520 |
On berrybyte, the runtime and port allocation are supplied for you. On a self-hosted machine, leave memory for the OS as well as the game process.
Choose a RAM plan
Use the Hytale server requirements calculator with your expected simultaneous players, view distance, and play style. Its recommendation is a berrybyte estimate, not a measured Chapter 1 benchmark.
- Start with a view-distance cap of 12 chunks or less, following Hypixel's performance advice.
- Allow more headroom for players exploring far apart or for multiple loaded worlds.
- Treat modded worlds separately; a vanilla estimate cannot account for every mod.
- Check busy-session RAM and Console for out-of-memory errors before increasing the player cap.
MaxPlayers controls admission. Increasing it does not add RAM or CPU.
See server settings.
When performance drops
| Symptom | First check |
|---|---|
| RAM stays near the plan limit | Reduce view distance and review mods; consider more RAM |
| Lag while players explore apart | Compare a session where the group stays together |
| Slow first boot after an update | Let the download and world loading finish |
| Crash after a mod change | Read the first mod error and check build compatibility |
Record the build, mod list, player count, and RAM usage when asking support for sizing help. Check the current allocations on Hytale hosting before choosing a plan.
Frequently asked questions
How much RAM does a Hytale server need?
Hypixel documents a 4 GB minimum. That is a floor, not a guarantee for a particular player count. View distance, loaded worlds, mods, and players exploring apart affect the allocation you need.
Is the Hytale calculator an official benchmark?
No. The calculator separates Hypixel's official minimum from berrybyte's planning estimate. Monitor your actual world during busy sessions before treating a plan as sufficient.
