Plan for your setup

What still needs a real-world check

A dedicated-server workload changes over time. Keep headroom for growth and test with the world, players, and content you actually plan to use.

Players and world state

The catalog does not assign a fixed player capacity. Active players, simulation range, entities, automation, maps, and save growth can all change CPU and memory demand.

Storage

Storage needs grow with your world. Leave room for the game, saves, logs, updates, and backups, and check the complete game guide for recommendations.

Home network

Players connect over TCP. The upload speed and latency you need depend on the game and number of players. Connection stability, route quality, and simultaneous household traffic matter.

CPU model and other work

Core count alone does not describe single-core speed, CPU generation, thermals, or contention from other programs. Test performance with your intended world and players.

Content and operations

Managing Minecraft Java

Review the available content, backup, and server tools before choosing your setup.

Mods & Content

Guided provider-backed content

Mods & Content verifies and reconciles one exact Modrinth server-pack revision. BlueMap is a separate optional managed integration resolved to the latest compatible Modrinth release for the selected Minecraft version and loader.

Persistent data

1 backup data location

Check the game guide for the files included in backups and allow room for several restore points.

Server controls
