StealthCore

⚡ StealthCore

Fast, Smooth, Unstoppable — PvP Ready

A lightweight, client-side Fabric modpack built for competitive Minecraft. Every mod earns its place. Nothing is wasted.

🎯 Overview

StealthCore is a combat-focused optimization modpack for Minecraft Java Edition 1.21.1 & 1.21.11 running on Fabric. It’s fully client-side — drop into any server and every feature works immediately, no server-side install needed.

The goal is simple: more FPS, sharper controls, cleaner UI, better information — everything a serious player needs and nothing they don’t.
