Bring JavaScript and Web Dev to 
A W3C/WHATWG‑compliant web runtime for Flutter that implements HTML, CSS, and the DOM, running JavaScript in a browser‑like environment.
Beyond Browser Performance
We made breakthroughs in the most critical issues of browser engine pipelines. Page opening in WebF takes less than 100ms, delivering native-like performance that redefines what's possible for web applications.
Web Tech Stack Just Works
Implements W3C/WHATWG standards with a browser-like JS engine. Run React, Vue, Svelte, Solid, Tailwind, Vite, Webpack—your entire web development stack inside Flutter apps with no modifications needed.
The Bridge to the Entire Flutter Ecosystem for Web Developers
Use any Flutter UI components in your React/Vue code and call any native libraries from the Flutter ecosystem. All the well-tested, popular Flutter packages are now available for web developers.

Google Flutter GDE
As a Flutter GDE, I turned to WebF because our project demanded high performance and true runtime dynamism. With WebF, we gained the flexibility to drive UI updates dynamically—while still enjoying the smooth, polished UX our users expect from Flutter. The experience? We could ship new features far more rapidly, reuse web-ecosystem patterns, and yet deliver an app that feels as native and performant as if we wrote every component in Dart. For anyone balancing dynamic content needs and Flutter-grade performance, WebF delivers on both fronts.
