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.
