# Is Flutter ready for the web yet? - A live coding comparison between Flutter and React

Is Flutter finally ready to rival React on the web? Watch Audi engineers live-code a direct comparison to reveal which framework wins for your next single-page app.

## Summary

The video explores whether Flutter is a viable alternative to React for web development through a live-coding comparison led by engineers at the Audi Software Development Center. As Flutter expands beyond mobile into web, developers face the decision of adopting its unified, cross-platform ecosystem or sticking with React's mature, DOM-native architecture.

Through hands-on examples rebuilding a corporate header component, the speakers contrast React's native HTML rendering and JSX separation with Flutter's CanvasKit and HTML renderers. While both frameworks share declarative programming paradigms and component-based architectures, their under-the-hood execution differs vastly. React produces clean, standard HTML DOM trees with incredibly fast Time to Interactive (TTI) metrics. Conversely, Flutter Web draws directly to a canvas, yielding 60fps performance for complex animations but suffering from slower startup times and an obfuscated DOM that requires the Flutter Inspector for debugging.

Ultimately, fetching data, managing state, and deploying progressive web apps offer remarkably similar developer experiences across both tools. The choice comes down to project requirements: React remains the standard for web-first applications requiring flawless automated accessibility scores and immediate load times. However, Flutter Web is highly recommended for single page applications, heavily animated UIs, and teams looking to deploy a companion web app by directly reusing an existing Dart codebase.
