Bento GUI
by Chai
Bento GUI is an expressive GUI library for Fabric that lets developers build dynamic screens from a set of ready-made interface elements.
What it does
Developers assemble screens from ready-made elements with a builder pattern, and the layout engine computes minimum and maximum dimensions for each element automatically. Element rendering can be customized, so a mod can change how parts of its interface are drawn. The library also replaces parts of Minecraft's own UI widgets, with a styling approach inspired by HTML and CSS.
Fabric API is required, and Bento Util is bundled inside the mod, so no separate install is needed for it. Only the client needs Bento GUI: it is client-side only and does not change anything on a server. Builds cover 1.21 and 1.21.1, and the latest file targets 1.21.1. The code is released under the GNU Lesser General Public License v3.0 only and is open source, with public links to the source code, issue tracker and wiki, and in-code JavaDocs.
Key features
Ready-made interface elements
Many UI elements are provided out of the box, so common controls do not have to be written from scratch.
Builder pattern
Elements are created by chaining builder calls, which keeps screen definitions short and readable.
Automatic layout sizing
The layout engine computes minimum and maximum sizes for elements, adjusting them as the screen content changes.
Customizable rendering
Element rendering can be changed, so mods built on the library can adjust how their components look.

Use cases
Dynamic mod screens
Mod developers can build configuration screens, menus or inventories that resize with their content.
Who it’s for: Fabric mod developers who want to create custom screens without laying out every widget by hand. Players only meet the library indirectly, through the mods built on it.
