Bossclient
by benw8021
Bossclient is a Fabric client mod for competitive PvP, with a HUD editor, a ClickGUI and combat, movement and render modules.
What it does
The client groups more than sixty modules under HUD, Combat, Movement, Render and Misc, so a player can set how the game looks, feels and performs. Each HUD element can be dragged and resized in an Edit HUD mode, and the ClickGUI offers a live search bar, category tabs and toggle switches for finding and changing a module quickly. Raw Input is available for pixel-perfect aim without acceleration, and a Mouse Tracker draws the path of the mouse on screen.
The mod includes a built-in FPS booster, custom hit feedback for combat, and a Spotify HUD that shows the playing track, album cover and an animated visualizer without leaving the game. Bossclient runs on the client alone, so players install it and servers need nothing. It is published for Fabric only, for game versions 1.21.4 and 1.21.11, with the 1.21.11 build as the latest file. The code is not open source and is licensed as All rights reserved.
