Which build do you need?

This mod ships a separate file for every mod loader and every version of the game. Pick both, then download — the wrong build installs fine and then does nothing in the game.

I don't know my version or loader

Open the Minecraft launcher and look at the profile you play on — it names both, like fabric-loader-1.21.4. The version also shows in the bottom-right corner of the game's main menu.

No loader in the profile name? Then it's plain Minecraft, and these mods won't run — you need Fabric or NeoForge installed first.

Gelatin UI is a modern, composable UI toolkit for Minecraft mod developers building on Fabric and NeoForge platforms. It provides a declarative, builder-style API for creating custom screens with components like labels, buttons, progress bars, item renderers, and flexible layouts using VBox/HBox containers. The framework features built-in performance optimizations including dirty flags, bounds caching, and automatic culling, along with smooth interpolation and keyframe animation support for polished user experiences. Developers get debugging tools with visual overlays and a comprehensive component system that's easy to extend with custom elements.
