OptiPack
Feature-rich Quality of Life pack, with OptiFine-like features and performance optimisations.
Quick answer
Which OptiPack release should I use?
OptiPack 1.4.3 is a complete pack release for 1.20.6 with Fabric 0.15.11. Install it as its own launcher instance. If the creator publishes a separate server file, make sure it names this exact pack release. 35 mods in this pack file.
Pack setup
How should I set up OptiPack for players and a server?
Use OptiPack 1.4.3 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.
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.
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 OptiPack?
OptiPack 1.4.3. Change the pack release and its contents or setup may change too.
The selected pack release is OptiPack 1.4.3. That file is for Minecraft 1.20.6 with Fabric 0.15.11. It contains 35 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.

What kind of pack is OptiPack?

QOL Optimisation Pack
OptiPack has long been a private pack of mods I have collected for my friends, most of whom play Minecraft on computers with processing power rivaling that of a potato (looking at you Wulfian!)
It is a pack that has been fine-tuned to fit our play style. I started making the pack as I wanted my friends to use the Fabric mod launcher, but still have all the features of OptiFine, but overtime was expanded to have other mods that would improve our gameplay experience, and deal with common gripes and problems we would encounter with the base game.

License
I am not very sure how a modpack is meant to be licensed. I didn't make any of these mods, but I guess my particular configuration can be licensed? IDK. Each mod has it's own license, which can be found with the provided links above. As for my particular configuration, saved in this modpack, I just went with unlicense.
