How to Make a Create Mod Server

Create today: versions and loaders

For a new server, NeoForge on Minecraft 1.21.1 is the default choice: it gets Create's updates first. The Create team skipped Minecraft 1.21.2 to 1.21.11 and is working on the next major version, so 1.21.1 is the current target. Since Create 6, the libraries it used to need (Flywheel, Ponder) are built into the jar.

RAM and CPU for Create

The Create team publishes no official server requirements, so this is our recommendation. Create itself is light; what grows is what players build with it — and big machines cost CPU as much as memory, because every moving contraption and train is simulated on the server's main thread.

Create is also part of many big modpacks; for the biggest of them, see how to make an ATM10 server.

Path A: set up a Create server yourself

1. Install Java 21 (Java 17 for a 1.20.1 server).
2. Install the loader. Run the NeoForge 1.21.1 installer and choose Install server into an empty folder. Create 6.0.10 needs NeoForge 21.1.219 or newer.
3. Start once, set eula=true in eula.txt, and stop.
4. Add the mods. Put the Create jar and your addons into mods. Download each addon for the same Minecraft version and loader as Create.
5. Set the memory in user_jvm_args.txt, for example -Xmx6G, and start the server.

The general steps for any modded server, including port forwarding, are in how to make a modded Minecraft server.

Popular Create addons, and the version catch

Addons extend Create with new machines and systems. The catch is that each one follows its own release schedule, so check that every addon exists for your Minecraft version and loader before you commit to it. As of October 2026:

• Create Crafts & Additions (electricity and more) — available for NeoForge 1.21.1.
• Create: Enchantment Industry (automated enchanting and experience) — available for NeoForge 1.21.1.
• Create: Steam 'n' Rails (more for trains) — still Minecraft 1.20.1 only. A group that wants it has to run Create 6.0.8 on 1.20.1.

Every addon a player sees in the world has to be installed on their game too.

Path B: a hosted Create server

1. Pick a plan on modded Minecraft hosting.
2. Install a Create-based modpack from the Modpacks tab in the panel, or run a NeoForge 1.21.1 server and upload Create and its addons to mods with the file manager.
3. Check Java in the Startup tab: Java 21 for 1.21.1, Java 17 for 1.20.1.
4. Start it and give friends the address.

Automatic backups are included — take one before updating Create or an addon, since mod updates are the most common way a factory breaks.

Friends joining, and keeping a big factory smooth

Every player needs Create, and the same version as the server, plus the same addons. A modpack makes this easy: everyone installs the same pack version through a launcher.

When the factory grows, the server feels it. What helps:

• Limit the biggest contraptions. Create's server config (create-server.toml in the world's serverconfig folder) caps how many blocks a contraption can move (maxBlocksMoved, 2048 by default) and how long trains can be (maxAssemblyLength, 128).
• Do not keep everything loaded. Chunk loaders keep distant factories running all the time; use them only where they matter.
• Pre-generate the map before a train network sends players far and wide.
• Measure before you guess. A spark profile shows which machines cost the most — see how to fix Minecraft server lag.
