Pack setup

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.
Referenced mods 19
Client only 9
Server only 0
Not labelled 10
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 Spirity BoostX?
Spirity BoostX 1.0.0 on 1.21.2. The pack contents and setup notes below stay tied to that release.
The selected pack release is Spirity BoostX 1.0.0. That file is for Minecraft 1.21.2 with Fabric 0.19.3. It contains 19 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.
