🧼 Clean Hitbox
Clean Hitbox is a lightweight Fabric client-side mod for Minecraft 1.21 that enhances the vanilla debug hitbox system (F3 + B) with improved visuals, better clarity, and combat friendly highlighting without changing any gameplay mechanics. Oe Just Use A "V" Keybind TO Open GuI
✨ Overview
Minecraft’s default hitboxes are useful but very minimal and hard to read during fast-paced combat. Clean Hitbox improves this by making them clear, customizable, and visually optimized so you can better understand entity positioning, range, and targeting in real time.
This mod is strictly visual-only and does not modify hit detection, reach, or combat mechanics.
