React DOM is a sibling of React Native that integrates directly with web APIs and allows you to use <div /> and <span /> directly instead of RN APIs like <View />. You're correct that there's no theoretical reason that RN apps can't run on the web; as dabbott mentions, react-native-web is one third-party attempt at this. We'd like to support this officially one day but don't currently have a high-quality solution we can recommend.
