Primitivas de componentes UI headless para React

Headless UI is a headless component library and accessible UI component kit that provides logic-only interface elements. It functions as a state-driven UI framework designed to provide functionality without prescribing any specific visual styles. The library is specifically designed for integration with Tailwind CSS, enabling the implementation of custom design systems. It allows users to apply visual styles to components based on whether they are active, selected, or open. The project covers the development of accessible UI components that meet ARIA standards and include built-in keyboard n

Reach UI is an open-source library of accessible, low-level React components designed to serve as a foundation for building design systems and interactive user interfaces. It is an accessibility-first toolkit that handles core concerns like ARIA attributes, focus management, and screen reader support automatically, without requiring developer configuration. The library is built as a collection of standalone packages, each managing its own lifecycle and dependencies, enabling granular adoption and tree-shaking. Components use a polymorphic rendering pattern, accepting an as prop to render as

Primitives is a library of unstyled, accessible building blocks designed for creating complex interface elements in React. It functions as a headless component framework, providing the underlying logic, state management, and accessibility compliance while leaving all visual styling and design decisions entirely to the developer. The library distinguishes itself through a composition-based architecture that allows developers to build interactive interfaces by nesting small, single-purpose components. This system automatically handles complex requirements such as WAI-ARIA attribute injection, f

Ariakit is a headless component library and accessible UI component toolkit. It provides a set of unstyled web components with built-in accessibility patterns to ensure that screen readers and keyboard navigation function correctly. The project includes an adaptive color engine that calculates high-contrast text and dynamic surface colors for light and dark modes. It also features a concentric layout engine for computing nested padding, margins, and border radii for circular interface elements, alongside a design token system for managing global CSS variables. The toolkit covers broad capabi

This project is a framework-agnostic library for building accessible, search-as-you-type interfaces. It provides a headless logic layer that decouples search state management and result filtering from the visual presentation, allowing developers to maintain full control over the underlying HTML structure and styling. The library distinguishes itself through a highly modular architecture that supports multi-source data aggregation, enabling the combination of results from static arrays, remote APIs, and external indices into a single interface. It features a flexible rendering engine that inte

Base UI is a headless component library and unstyled framework providing accessible interface primitives. It decouples behavioral logic and state management from the visual layer, allowing developers to implement complex UI patterns while maintaining total control over the final styling. The library implements WAI-ARIA design patterns to ensure all primitives support standard keyboard navigation and screen reader accessibility. It provides a suite of low-level building blocks that handle the internal mechanics of interface elements without bundling any CSS. The framework covers a broad range

Downshift is a headless UI component library and framework for React that provides the state and interaction primitives necessary to build accessible autocomplete, combobox, and select dropdown components. It functions as a WAI-ARIA UI framework, generating the required ARIA attributes and keyboard event handlers to ensure screen reader compliance without providing any default styling. The library utilizes a headless component pattern to decouple interaction logic from the visual presentation. It manages complex state transitions through reducers and synchronizes internal UI state with extern

Ark is a headless UI component library that delivers accessible, cross-framework primitives with behavior governed by finite state machines. It provides unstyled components that encapsulate logic and accessibility — including full keyboard navigation, focus management, and WAI-ARIA support — while leaving visual styling entirely to the consumer. Components expose scoped data attributes for CSS targeting and use state machines to produce predictable, testable interactive behavior across every state transition. The library distinguishes itself through a state propagation model that distributes
