uixt

Uixt is a cross-platform user interface toolkit designed to simplify the creation and rendering of modular UI components. The project emphasizes declarative composition, accessibility, and extensibility.

At its core, uixt consists of a rendering engine, a component set, and a plugin/extension system. Components are described in a platform-agnostic syntax (for example a JSON-like description) that maps to native widgets on target platforms, enabling a single source of truth for web, desktop, and mobile interfaces.

Key features include a modular component library, theming and design tokens, responsive layouts, and an extension mechanism for custom widgets. It provides accessibility support, keyboard navigation, and performance optimizations such as incremental rendering and virtualization.

Developers can integrate uixt with popular front-end frameworks through adapters, enabling usage within existing apps. The toolkit supports hot reloading, design-time previews, and rapid prototyping.

Origin and license: Created by a small open-source team; first release in 2021; maintained on GitHub under an open-source license. The community is modest but active, with occasional conference talks and tutorials.

Common use cases include prototyping, design-to-implementation pipelines, and educational demos.
