Demo Client

by DemoTheShy

Demo Client is a free, lightweight Fabric client utility for Minecraft 1.21.1, built around a sleek Click GUI and a set of HUD modules that can be placed anywhere on screen.

What it does

The mod groups its HUD modules and gameplay helpers into one interface. Players can show or hide modules such as FPS, ping, coordinates, speed, a clock, CPS and keystrokes, plus armor, potion status, reach display and a nametag view. A draggable HUD editor lets each element be moved and placed to suit the screen layout.

Gameplay helpers in the same set include fullbright, hitbox display, auto sprint and free look. Right Alt opens the Click GUI, and Right Shift opens the configuration screen. Settings are saved between sessions, so the layout persists after the game closes.

Demo Client requires Fabric API, so both must be installed for the mod to load. It is a client mod: only the player needs it, and servers run without it. The author describes it as a beta release, so bugs and missing features are expected, and updates are planned to add features and improvements based on feedback. The mod is distributed under All rights reserved and is not open source.

Key features

  1. Draggable HUD modules

    Readouts for frame rate, latency and position can each be moved across the screen.

  2. Click GUI

    A graphical menu opened with Right Alt lists the modules and lets players toggle them without editing files.

  3. Visual helpers

    Fullbright, hitbox display, nametag view and free look change how the world is shown on the client.

  4. Combat and movement aids

    Reach display and auto sprint give players readouts and automatic sprinting during play.

  5. Saved settings

    Configuration is kept between sessions, and Right Shift opens the settings screen.
