Pack setup

How should I set up Keo optimized for players and a server?

Use keo optimized neoforge 1.21.1.zip 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.

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 58

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 Keo optimized?

keo optimized neoforge 1.21.1.zip on NeoForge. The pack contents and setup notes below stay tied to that release.

58 mods in this pack file

The selected pack release is keo optimized neoforge 1.21.1.zip. That file is for Minecraft 1.21.1 with NeoForge 21.1.219. This NeoForge setup needs Java 21. It contains 58 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.
