KubeUI
by Zynora
KubeUI lets KubeJS scripts build interactive graphical screens for NeoForge, using controls and layouts that the game already provides.
What it does
KubeJS scripts can react to game events, but building a custom screen has normally meant writing a Java mod. KubeUI is an addon that closes that gap, offering controls such as toggles, sliders, dropdowns and progress bars, along with draggable and resizable windows and scrollable lists.
Screens built this way use the same layout system as vanilla Minecraft's own option screens, including GridLayout and ScrollableLayout, so windows look and behave like the rest of the interface. KubeUI requires KubeJS and runs on the client and the server together. It is published for NeoForge 1.21.1 and 26.1.2 under the MIT License and is open source; its source code, issue tracker and wiki are public.
Key features
Interactive controls
Buttons, toggles, text fields, sliders and dropdowns can be placed on a screen from a script.
Item icons and progress bars
Screens can show item icons and progress bars for machines, crafting or status displays.
Tabs and windows
Tabbed panels, draggable windows and resizable windows organize content across a screen.
Scrollable lists
Long lists of entries scroll inside a window instead of overflowing the screen.
Single fluent builder
One builder API assembles every control, so a complete screen takes a few chained calls.

Use cases
Custom machine screens
A script can show a machine's progress bar, item slots and settings toggles in one window.
Server menus
Scripted server tools can present a dropdown or a text field to a player through a window they open.
Who it’s for: Modpack authors and scripters who already use KubeJS and want custom screens without writing Java. Server owners who run KubeJS scripts can rely on the same screens on their side as well.
How it compares
NetworkJS-Reloaded is a NeoForge 1.21.1 addon that is server-side only and open source under the MIT License. NeoGeckoJS is a NeoForge 1.21.1 addon that requires both client and server and uses a custom license, so it is not open source. KubeUI is client and server, open source under the MIT License, and built for NeoForge 1.21.1 and 26.1.2.
