Quick answer
Which Spunky Optimized release matches 1.21.5?
Spunky Optimized 1.21.5.zip is a complete pack release for 1.21.5 with Fabric. Install it as its own launcher instance. If the creator publishes a separate server file, make sure it names this exact pack release. Could not safely read this pack file.
Pack setup
How should I set up Spunky Optimized for players and a server?
Use Spunky Optimized 1.21.5.zip 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.
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.
What are the server requirements for Spunky Optimized?
Spunky Optimized 1.21.5.zip on 1.21.5. The pack contents and setup notes below stay tied to that release.
The selected pack release is Spunky Optimized 1.21.5.zip. That file is for Minecraft 1.21.5 with Fabric. We could not safely count the mods in this release. 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.
