Pack setup

How should I set up Feather Boost for players and a server?

Use Feather Boost 1.21.11 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 Feather Boost 1.21.11
Dedicated server setup Match Feather Boost 1.21.11
Pack loader Fabric 0.17.2

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 15
Client only 8
Server only 1
Not labelled 6

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 Feather Boost?

Feather Boost 1.21.11. Change the pack release and its contents or setup may change too.

15 mods in this pack file

The selected pack release is Feather Boost 1.21.11. That file is for Minecraft 1.21.11 with Fabric 0.17.2. It contains 15 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.
