andrsrxn/icons is a React icon library featuring 1,000+ duotone icons and 250+ country flags with RTL support, designed as a standalone foundation for an enterprise design system. The library takes a deliberate approach to icon variants, using duotone only when meaningful, outline for simple shapes, and filled variants selectively, all optimized as SVGs and freely available under MIT License.
