Expo Snack lets you run Expo in the browser.

Try Expo Snack at snack.expo.dev

Expo Snack is an open-source platform for running React Native apps in the browser. It dynamically bundles and compiles code and runs it in the Expo Go or in a web-player. Code can be saved as "Snacks" and easily shared with others. Snacks can also be embedded to show "live" previews as used by the React Native documentation.
