# UI SDK

> Composable UI behaviors for agents building accessible interfaces

UI SDK is an open-source library that helps developers and coding agents build interfaces from reusable behaviors. It separates interactions such as keyboard navigation, focus management, selection, popups, and drag and drop from visual styling, so teams can combine them into controls tailored to their applications. The same core works with adapters for React, Vue, Svelte, Solid, and Web Components.

Developers can start with the supplied component library or give their coding agent the UI SDK skill to assemble a custom component. Behaviors include accessibility support and can be combined into familiar elements such as selects, comboboxes, and pickers. The project is publicly available in beta, with documentation and source code for exploring and adapting its building blocks.
