Estimate RAM, CPU, world size and storage for your Hytale server
Choosing how much RAM, how much disk and what kind of machine to rent is the first question for anyone opening a Hytale server. This calculator gives a starting point based on the published dedicated-server requirements in Early Access: it runs on Java 25 (x64 and arm64), with roughly 4 GB of RAM for small unmodded groups, 6 to 8 GB as a general recommendation and 10 to 12 GB for heavily modded servers, always on NVMe SSD. The key thing here is world size: because Hytale is voxel and high-fidelity, worlds are heavier than Minecraft's, and what drives disk use most is not the player count but how much of the world has been explored or pregenerated. That is why you pick the world scope, and the tool separates world size from total storage (which already includes headroom for backups, mods and server files).
Paste the code into your HTML and the tool shows up on your page, without J-Kit's navigation and ads. It still runs in the browser of whoever visits your site.

Because the world is what grows most on disk, and it grows as players explore, not simply because there are more players. A fresh world weighs almost nothing; a heavily explored or large-radius pregenerated world can take tens of GB. That is why the tool asks for the world scope and shows that value separately from total storage.
A starting estimate, not an official requirement. Hytale is in Early Access and requirements may change. World size depends heavily on how much is explored or pregenerated; total storage already includes headroom for backups, mods and server files. Always monitor real usage.
The estimate is computed locally in the browser; nothing is sent to servers.
