React Native Web compiles React Native's native-style component API down to standard DOM output, letting teams share a single codebase between a mobile app and a web app. Sites built this way carry a distinctive fingerprint even after compilation: `react-native-web`-generated class names and accessibility data attributes (like `data-focusable`) that don't appear in ordinary web-first React code, revealing that a site is really a secondary web build of a primarily-mobile codebase.
