About this Mod

The Moon Client is an advanced Fabric 1.21.11 client that combines top-tier aesthetic quality with best-in-class performance features. The heart of the project is its Smoothest UI that offers double layer mod menu as well as full interactive HUD editor complete with drag-and-drop placement and module label customization.

The client includes over 40 integrated mods divided into four groups: Performance, Visual, Utility, and Information. Performance in combat gets a boost through custom crosshair pixel editor with coloring according to reach distance and the amazing 360° Freelook mod built around the body of the player. Exploring the world will be easier than ever with the advanced 3D Waypoints functionality that includes beacon beams, distance labels, filter by dimension feature, and adjustable tiers of the Zoom mod.

Real-life information will be displayed using information HUD mods dedicated to tracking FPS, CPS, coordinates, keystrokes, and armor status. Visually, the client features such premium features as 3D item physics, HitColors customization, and enchantment glint effect refinement. Technical features include JSON configuration system, entity culling optimization, and Mixins with minimum latency.
