Best match for your filters Embeddium-1.21-1.5

Loader NeoForge 21.0.167

Embeddium-1.21-1.5 is a complete pack release for 1.21 with NeoForge 21.0.167. Install it as its own launcher instance. If the creator publishes a separate server file, make sure it names this exact pack release. For this loader, use Java 21. 14 mods in this pack file.

Pack setup

How should I set up Optimization for players and a server?

Use Embeddium-1.21-1.5 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.

Dedicated server setup Match Embeddium-1.21-1.5
Pack loader NeoForge 21.0.167
Java version Java 21

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 14
Client only 7
Server only 0
Not labelled 7

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 Optimization?

Embeddium-1.21-1.5 on 1.21 NeoForge. The pack contents and setup notes below stay tied to that release.

14 mods in this pack file

The selected pack release is Embeddium-1.21-1.5. That file is for Minecraft 1.21 with NeoForge 21.0.167. This NeoForge setup needs Java 21. It contains 14 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.
