Radix UI vs. React Spectrum vs. Shoelace vs. Vue.js Comparison Chart

​Radix UI is an open source component library optimized for fast development, easy maintenance, and accessibility. It offers two main packages, Radix Primitives and Radix Themes. Radix Primitives is a low-level UI component library focused on accessibility, customization, and developer experience. Components adhere to WAI-ARIA design patterns, are unstyled by default, and provide full keyboard navigation. Radix Themes is a pre-styled component library designed to work out of the box with minimal configuration. It includes layout primitives, typography, and components like buttons and cards, all customizable via the Theme component. Radix Colors offers a comprehensive, accessible color system for designing beautiful, accessible websites and apps. It supports automatic dark mode, transparent variants, and is designed for user interfaces. Radix Icons provides a crisp set of 15×15 icons available as individual React components.

Shoelace is a forward-thinking, open source library of web components built on web standards that enables developers to embed a comprehensive suite of accessible, customizable UI elements, such as buttons, modals, tabs, inputs, popups, text areas, icons, trees, skeleton loaders, and more, into any project without being tied to a specific framework or CDN. It includes modern design utilities like design tokens for typography, color, spacing, elevation, border radius, transitions, and z-index, and supports themes including a built-in dark mode. Fully compatible with all frameworks (and also framework-less implementations), Shoelace components are customizable via CSS, support localization, and prioritize accessibility with thoughtful defaults. Features include runtime component loading via an autoloader, seamless form integration, including shadow-DOM-aware form controls and utilities for serializing form data and validation, and icon support.
