Ykrez Client

Ykrez Client is a lightweight, server-legal quality-of-life client for Fabric. It gives you a clean, fully customizable HUD, a handful of useful visual tweaks, and an in-game menu you can arrange however you like — no cheats, no hacks, nothing that puts your account at risk. It's built for players who just want a better-looking and more informative Minecraft.

Minecraft 1.21.11 | Fabric | Java 21

HUD

Show exactly the info you want on screen: FPS, FPS graph, CPS and right-click CPS, coordinates, speed, facing direction, yaw/pitch, ping, real-time clock, in-game day, biome, health, hunger, XP level, held item, armor display, player count, memory usage, session timer, keystrokes (WASD and mouse), an enabled-module list, and a watermark.

Visual tweaks

Fullbright, Zoom, an adjustable FOV, and a custom crosshair.

Customizable menu

  • All-black, rounded, animated menu with category dropdowns
  • Draggable panels so you can lay the menu out your way
  • Scroll to pan when you have a lot enabled
  • Right-click any module to open its settings — sliders and toggles let you set your exact FOV, zoom level, gamma, crosshair size, and more
  • Everything saves automatically and is restored the next time you launch

Controls

  • Right Shift — open the menu
  • V — Zoom
  • B — Fullbright
  • R — Toggle Sprint

All keys are rebindable in Options > Controls. In the menu: left-click toggles a module, right-click opens its settings, drag a header to move a column, and scroll to pan.

  • Minecraft 1.21.11
  • Fabric Loader (0.16 or newer)
  • Fabric API

YKREZ client server crashes on startup – what to do?

Server lagging with YKREZ client – how to optimize performance?

Recommended RAM: 4 GB (per 8 players). Use /spark profiler to check if YKREZ client consumes the most tick time.
