OpenUI MC

OpenUI MC is a client-side UI framework used by Minecraft mod developers to build polished, reactive screens without rewriting focus, input routing, layout, animation, and widget lifecycle plumbing.

For players

OpenUI MC is a library mod. It does not add blocks, items, recipes, or gameplay by itself. Install it when another mod lists OpenUI MC as a required dependency, and make sure the Minecraft version and loader match that mod.

For mod developers

Declarative rows, columns, stacks, padding, clipping, responsive layouts, grids, and virtual lists
Reactive signals, computed values, effects, batching, remembered state, and async state
Buttons, text fields, toggles, sliders, selects, tabs, tables, charts, forms, and validation
Managed focus, keyboard navigation, pointer capture, drag and drop, and native Minecraft widgets
Dialogs, popovers, menus, tooltips, toasts, command palettes, and layered overlays
Themes, animations, navigation, error boundaries, and UI inspection tools
Base classes for ordinary screens and menu/container screens

OpenUI MC keeps application code focused on state and business callbacks while its runtime mounts components, computes layout, renders, dispatches input, owns focus, and cleans up resources.

Supported platforms

Developer documentation

Important 26.1.2 note

Minecraft 26.1.2 uses its extracted GUI render-state API. OpenUI supports that API, but FadeTransition is unavailable because Minecraft no longer exposes a safe scoped opacity operation for arbitrary UI subtrees. Slide and scale transitions remain available.
