Uni GUI

by Sixik

Uni GUI is a library for building user interfaces in Minecraft, built on a UI framework and tied directly to the game renderer.

FabricForgeClient required, server optionalGNU Lesser General Public License v3.0 onlyOpen source1.20.1

What it does

The library provides a UI framework built on the Unigine engine, aimed at high UI performance while staying portable. It hooks into the Minecraft renderer directly, so it does not require a full rewrite of the core to run. Its stated goal is to write a UI once and run it on every supported loader. Players need it on their client, while the server can run without it. Files are published for Fabric and Forge for 1.20.1, released under the GNU Lesser General Public License v3.0 only, and the project is open source.

Key features

  1. Batched drawing

    A dedicated DrawCommands system groups tasks into batch buckets to reduce the cost of drawing each interface element.

  2. Renderer integration

    The framework is tied to the Minecraft renderer, so interfaces are drawn through the game's own pipeline.

  3. Vanilla context handling

    The library is integrated with the Minecraft context, which addresses issues that come from working outside the game's own structure.

What the author says

UniGUI is a UI framework built on top of my library for the Unigine engine. It is designed not to be directly tied to the Minecraft renderer, making it portable without requiring a complete core rewrite. The main goal of this library is to deliver maximum UI performance and follow the "write once, run anywhere"…
