Mods need Forge/Fabric — how do I set that up first?
Before you can install mods, your server has to be running a mod loader — Forge, NeoForge, Fabric, or Quilt. Setting that up is a one-click job on the Software page.
Setting up a mod loader
- Open the Software page (click the Version chip at the top of the console).
- Choose Forge (or NeoForge/Fabric/Quilt) and the Minecraft version you want.
- Install — your world is kept (files the install replaces are moved to a
_previousfolder). - Once it's running as a Forge/Fabric server, the Mods & Plugins page and the
modsfolder become the place to add mods.
Adding your first mods
After the loader is running, open the Mods & Plugins page, install your mods, and restart the server.
Tip: Mods don't run on Vanilla or Paper — the loader has to come first, which is exactly what the Software page sets up.
Frequently asked questions
Which loader should I pick? Match whatever your mods target — Forge, NeoForge, Fabric, or Quilt.
Will setting up the loader wipe my world? No — the Software page keeps your world; any files it replaces are moved to a _previous folder.
