Shiru's Improvements
by Seal Squad
Shiru's Improvements is a client-side quality-of-life package for Fabric on 1.21, bundling a zoom, brightness, HUD and warning tools into one lightweight mod.
What it does
Players get a set of small client features in one package: a Fullbright Zoom that brightens dark areas and lets players see distant objects, a customizable top-left HUD and a durability warning above the hotbar. Each feature can be switched on or off, and the mod is meant to be toggled from its config screen. Shiru's Improvements requires Fabric API, and Cloth Config API and Mod Menu are optional companions for the config screen.
The mod is published for Fabric only, with a single build for 1.21 released 2025-04-30 under the MIT License. It is not open source. Because only the client needs it, players can join servers without installing anything, and the mod works in single-player and multiplayer alike. The author describes it as light on performance, and the HUD and warning features are built to stay out of the way of play.
Key features
