Material UI (MUI) is the most widely adopted React implementation of Google's Material Design system, used across everything from indie SaaS products to large enterprise dashboards for its comprehensive component set and familiar design language. Our engine detects MUI with 1 script pattern and 4 HTML patterns — the richest HTML signal set among the UI libraries we track — reflecting its consistent `Mui`-prefixed class names and data attributes applied across every component instance. Detection identifies the front-end component library, not the backend or hosting setup. Documented at mui.com.
