R-Ui Lib

R-Ui Lib gives Minecraft mods a shared set of reusable components for building clear, consistent screens. It adds no standalone screens, blocks, or items; players see it through the mods that depend on it.

Minecraft	Loader	Minimum version
1.20.1	Forge	47.4.20
1.21.1	NeoForge	21.1.236

For players

Install the library alongside a compatible mod that requires it, using matching Minecraft and loader versions. The consumer mod determines which screens and features use the library.

Installation and requirements

For developers
