Game version 26.1.2
Loader Fabric 0.20.1

Pack setup

How should I set up Just Optimized for players and a server?

Use Just Optimized 1.4.0 as the pack version. Install the pack as its own launcher instance. The creator’s listing does not name a separate server file, so check the release notes before setting up a dedicated server. Do not upload the ordinary client folder blindly.

Client instance Install Just Optimized 1.4.0
Dedicated server setup Match Just Optimized 1.4.0
Pack loader Fabric 0.20.1

A pack is a matched client and server setup, not one mod with an install-side label. Keep its release, loader, manifest and overrides together.

Plan the server requirements Read the Minecraft installation guide
Referenced mods 30
Client only 16
Server only 0
Not labelled 14

These numbers come from the pack file you chose. “Not labelled” means we don’t know which side it belongs on—not that it is safe everywhere. The file count is not a RAM estimate.

What are the server requirements for Just Optimized?

Just Optimized 1.4.0. Change the pack release and its contents or setup may change too.

30 mods in this pack file

The selected pack release is Just Optimized 1.4.0. That file is for Minecraft 26.1.2 with Fabric 0.20.1. It contains 30 mod projects. The creator’s listing does not name a separate server file. Check their notes before using one, and do not upload an ordinary client folder or rebuild the pack mod by mod. A file count cannot tell us the right RAM, CPU or storage; size the server for the players and world you actually run.
