Official baseline
The current Hytale server manual specifies:
- Java 25.
- At least 4 GB of memory.
- x64 and arm64 support.
- UDP port 5520 by default, using QUIC rather than TCP.
- Authentication through Hytale services before accepting normal player connections.
universe/for world and player data, with configuration in files such asconfig.jsonandpermissions.json.
Four gigabytes is an installation floor, not a universal sizing recommendation. Player count, NPCs, mods, view distance, and players exploring separate areas can raise CPU and memory requirements substantially. Measure the real workload and set an explicit Java heap limit appropriate for the host.
Release compatibility
Hytale currently requires the client and server to use the same protocol version. Update the server promptly when the release client changes, and do not mix release and pre-release files, worlds, or mods without a tested rollback plan.
