GaminiUI

GaminiUI is an open-source user interface framework intended for building cross-platform applications. It adopts a component-based model with a declarative API, aiming to minimize boilerplate while delivering predictable rendering and strong type safety in supported languages.

Its design prioritizes performance and accessibility. GaminiUI provides design tokens for theming, built-in focus management and ARIA-compliant components, and internationalization support suitable for right-to-left languages.

Architecturally, GaminiUI consists of a core runtime and renderer backends. It uses a reactive data model and a lightweight virtual rendering pass that updates only changed elements. The framework supports web targets and can integrate with native-like environments through adapters.

Developers build interfaces by composing reusable components, managing state with a unidirectional data flow, and styling through tokenized themes or CSS-in-JS style definitions. The API is designed to be small and consistent, with emphasis on predictable behavior and easy testing.

History and ecosystem: GaminiUI emerged from a community project in the early 2020s. While not as large as some established frameworks, it has a dedicated contributor base and a growing set of third-party components, tooling, and examples.

Licensing and reception: The project is released under an open-source license (primarily permissive). It is used in small to mid-sized projects where a lightweight, accessible UI toolkit is preferred. Some critiques note limited ecosystem maturity and plugin availability relative to larger rivals.
