About this Mod
✨ SimpleHitbox
SimpleHitbox is a client-side Fabric mod that reimagines how hitboxes look and behave in Minecraft, giving you full control over their appearance in a clean and intuitive way.
🎨 Customization
Instead of the default vanilla outlines, SimpleHitbox allows you to fully customize hitboxes with your own colors, transparency, and line thickness. The result is something that not only looks better, but is also much easier to see and work with in any situation.
🧠 Per-entity control
Every entity can be configured individually, giving you precise control over how different mobs or players are displayed. Whether you want subtle tweaks or completely different styles, everything is adjustable to match your needs.
✨ Animated visuals
To make things more dynamic, the mod includes multiple animation styles such as pulsing, flickering, glowing, and smooth rainbow transitions. Hitboxes are no longer just functional — they can actually look good.
🖥️ Simple and clean GUI
All settings are available through an in-game interface that is designed to be fast and easy to use. You can open it with a single key and change everything on the fly, without touching any config files.
