ONClient
by sxmxon111
ONClient bundles a set of client-side quality-of-life tools into one Fabric mod for Minecraft 1.21.11, with HUD elements, a cape and a built-in toggle menu.
What it does
Each module can be switched off from a clean built-in GUI menu, so a player keeps only the features they want. The modules include an FPS counter that shows real-time eye frames per second, an input display that shows the WASD, Space, LMB and RMB keys on screen, a coordinates display with a compact X/Y/Z readout and facing direction, and an armor HUD that tracks durability in the main view. A dedicated zoom function magnifies distant objects, a brightness option makes caves less dark, and an auto sprint option keeps the player running without holding extra keys.
The mod adds a custom cape, with an exclusive built-in ONClient cape to show. It is client-side only: a player installs it on the Fabric client and the server needs nothing. Files are published for 1.21.11 only, and the mod is released under All rights reserved, so it is not open source. The mod is built to stay lightweight, and it is meant to sit alongside existing modpacks and custom mod setups rather than replace a launcher.

Zoom and brightness
