Bring JavaScript and Web Dev to 
The high-performance W3C/WHATWG compliant web runtime for Flutter. Use your favorite web frameworks like React and Vue to build native apps with direct access to the entire Flutter ecosystem.
Beyond WebView Performance
WebF is a custom high-performance runtime, not a system WebView wrapper. We optimized the rendering pipeline to deliver <100ms startup times and smooth native-like responsiveness.
Zero-Config Web Stack Support
Your existing stack just works. Run React, Vue, Svelte, and Tailwind directly in Flutter. No rewrites, no compromises—just standard web development.
Instant Over-the-Air Updates
Bypass App Store reviews and ship instantly. Deploy bug fixes, UI changes, and new features in real-time using standard web technologies.
Unite Web and Flutter
Seamlessly mix worlds. Embed Flutter components in your HTML or invoke native Flutter plugins from JavaScript. Access the full power of Dart and Pub.dev packages.

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.
