About this Mod

🚀 ONClient – The Ultimate Vanilla+ HUD & Feature Client

ONClient is a sleek, all-in-one modification for Minecraft 1.21.11 designed to enhance your gameplay with essential Quality-of-Life features, wrapped in a beautiful, modern, and minimalist user interface.

Unlike heavy, bloated client launchers that restrict what you can play, ONClient is lightweight and built with maximum compatibility in mind—making it the perfect addition to your existing modpacks or custom mod setups!

⚠️ 100% Fair Play: ONClient is purely a Quality-of-Life utility. It contains no cheats, no hacks, and no unfair advantages. It is fully compliant and safe to use on your favorite multiplayer servers!


🧩 Great Mod Compatibility

ONClient doesn't touch engine rendering or performance internals, meaning it works perfectly alongside other mods. Whether you want to pair it with Sodium, Iris Shaders, or your favorite gameplay mods, ONClient blends right into your setup without causing conflicts.


🔥 Features & Modules

Easily toggle your modules on or off using our clean, built-in GUI menu:

📺 Render & HUD

  • FPS Counter: Keep a crisp, real-time eye on your frames per second.
  • Keystrokes: Displays your movement and mouse inputs (WASD, Space, LMB, RMB) directly on screen—perfect for PvP or recording content.
  • Coordinates Display: A compact HUD element showing your current X/Y/Z position and facing direction.
  • Fullbright: No more pitch-black caves. Perfect visibility, anytime, anywhere.
  • Armor HUD: Keep track of your armor's durability right in your main view.
  • Zoom: Smoothly focus on distant objects with a dedicated zoom function.
  • Custom Cape: Show off your exclusive, built-in ONClient cape!

🏃 Movement

  • Auto Sprint: Automatically sprint without continuously holding down extra keys.
  • Toggle Sneak: Keep sneaking toggled with a single press to save your fingers.

📌 Current Limitations & Future Plans

  • Fixed HUD Positions: Please note that HUD elements (like Keystrokes, FPS, and Coordinates) currently have fixed screen positions and cannot be dragged or repositioned yet.
  • What's Next: Full HUD customization, element resizing, and draggable modules are planned for an upcoming release!
