Lion is a set of highly performant, accessible, white-label Web Components built on LitElement, intended as a foundation for building your own design system. It ships both Web Components and JavaScript classes that are unopinionated and designed to be extended rather than used as-is.

Use cases

• build a custom design system on accessible web components
• create white-label form components without overriding styles
• make my web app WCAG 2.2 AA compliant
• extend accessible input, select, and dialog components
• use framework-agnostic UI components in any frontend stack
• reuse component documentation across products

When to choose

• you want a styling-agnostic foundation to build a design system on
• accessibility compliance (WCAG/WAI-ARIA) is a hard requirement
• you prefer standards-based Web Components over framework-specific UI kits
• you need small, fast components with minimal dependencies

When to avoid

• you want ready-made, fully styled components out of the box
• your team is not comfortable extending and maintaining a component layer
• you need a component library tied to a specific framework like React or Vue
