Quick answer

Which OptiFabriс release matches 1.21.2?

Updated last month
Best match for your filters 6.2.3
Game version 1.21.2
Loader Fabric 0.18.6

6.2.3 is a complete pack release for 1.21.2 with Fabric 0.18.6. Install it as its own launcher instance. If the creator publishes a separate server file, make sure it names this exact pack release. 36 mods in this pack file.

Pack setup

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

Use 6.2.3 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 6.2.3
Dedicated server setup Match 6.2.3
Pack loader Fabric 0.18.6

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 36
Client only 15
Server only 0
Not labelled 21

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 OptiFabriс?

6.2.3 on 1.21.2. The pack contents and setup notes below stay tied to that release.

36 mods in this pack file

The selected pack release is 6.2.3. That file is for Minecraft 1.21.2 with Fabric 0.18.6. It contains 36 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.
