How to Create a Forge Minecraft Server

What Is Forge and When to Use It

Forge has the deepest mod ecosystem in Minecraft, including tech, magic, exploration and large kitchen-sink modpacks that have been maintained for years. Choose Forge when a specific mod or modpack requires it, or when NeoForge (the Forge successor) is listed as a dependency — NeoForge servers use the same creation flow with the NeoForge software type.

Create Your Forge Server on Ametistos

1. Create a new server and select Forge(or NeoForge, if the pack requires it) as the server software.
2. Match the exact Minecraft version the modpack targets — Forge builds are strictly version-locked.
3. Select the Java version documented by the modpack; large packs commonly need more memory headroom than plugin servers.
4. Allocate RAM using the pack author’s recommendation, not a generic default.

Install a Forge Modpack

Ametistos installs Modrinth modpacks with the loader, Minecraft version and Java runtime matched automatically. For the full walkthrough of checking requirements, allocating resources and confirming a successful start, see How to Install a Modrinth Modpack on a Minecraft Server .

Performance Tips for Large Modpacks

• Large kitchen-sink packs can need significantly more RAM than a plugin server with the same player count — budget credits accordingly before launch.
• Every connecting player needs the identical modpack version installed client-side, or the connection will fail.
• When startup fails, check the first relevant console error rather than the final shutdown line — Forge logs are verbose.
