Quick answer

Which OptimisticMC release should I use?

Updated last month
Latest stable file OptimisticMC 26.2v1
Game version 26.2
Loader Fabric 0.19.3

OptimisticMC 26.2v1 is a complete pack release for 26.2 with Fabric 0.19.3. Install it as its own launcher instance. If the creator publishes a separate server file, make sure it names this exact pack release. 24 mods in this pack file.

Pack setup

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

Use OptimisticMC 26.2v1 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 OptimisticMC 26.2v1
Dedicated server setup Match OptimisticMC 26.2v1
Pack loader Fabric 0.19.3

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 24
Client only 11
Server only 1
Not labelled 12

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 OptimisticMC?

OptimisticMC 26.2v1. Change the pack release and its contents or setup may change too.

24 mods in this pack file

The selected pack release is OptimisticMC 26.2v1. That file is for Minecraft 26.2 with Fabric 0.19.3. It contains 24 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.
