Cat Client
by M3TheCat
On the client only, Cat Client installs as a Fabric mod for 1.21.11, adding a HUD overlay, a main menu that can be reshaped, a built-in cape system and a set of quality-of-life switches.
What it does
The HUD modules show FPS, TPS and worn armor on screen, so players can keep track of performance and gear without opening a menu. A smooth zoom function is included as well, and the HUD can be arranged to suit the player.
Beyond the HUD, the mod gives the main menu a personal look that players can adjust, and includes a built-in cape system that displays a chosen cape in-game. Small daily conveniences such as Fullbright and Toggle Sprint are part of the same package.
Cat Client is a Fabric mod with the client-side only environment, so only the player's game needs it and servers run without it. It is published for 1.21.11 alone, released under All rights reserved, and is not open source. Public documentation is available on the wiki.
