Beyond WebView Performance
WebF achieves native-like performance by fundamentally rethinking how web content is loaded and rendered. Our split-phase architecture delivers <100ms page loads.
Split-Phase Rendering Pipeline
The key to WebF's performance is splitting the rendering pipeline into two independent phases. This allows background initialization while users interact with your native Flutter UI.
System WebView: Sequential Pipeline
All steps must execute in series on every page load
WebF: Split-Phase Pipeline
Phase 1 runs in background, Phase 2 runs on demand
Executes while user interacts with native Flutter UI. State kept in memory.
Only layout & paint execute when user opens the WebF view. Same as native Flutter!
Why This Matters
When a user navigates from a native Flutter page to a WebF view, they experience the same loading performance as navigating to another native Flutter page. The heavy lifting (JS execution, DOM construction, CSS processing) has already happened in the background. This is impossible with system WebView, which must execute all steps sequentially every time a page loads.
Shared Context, Persistent DOM
WebF's hybrid router design enables efficient navigation by sharing JavaScript context and preserving DOM nodes across route changes.
WebView Navigation
- Destroy Page A's DOM & JS context
- Load Page B from scratch
- Re-initialize entire JavaScript runtime
- Full rendering pipeline again
WebF Hybrid Router
- Single JS context shared across pages
- DOM nodes persist between navigations
- Only differential updates applied
- Instant state preservation
20x Cheaper DOM Mutations
Deferred RenderObject creation
Every appendChild() immediately creates render objects, triggers style calculation, and schedules layout. Building a complex page means thousands of expensive operations.
DOM mutations in WebF are lightweight pointer operations. RenderObjects and layout are only created when the element becomes visible. This makes page construction dramatically faster.
Native Performance, Minimal Code
Flutter Native UI components encapsulate complex animations and state management in Dart, delivering native-level performance while keeping your JavaScript code light and focused.
JavaScript-Based UI
- Animations run on JS thread, competing with business logic
- Complex state management adds bundle size
- 60fps animations are hard to achieve consistently
WebF Native UI Components
- Animations run natively in Dart at 60fps guaranteed
- Complex logic hidden in Flutter, your code stays simple
- Smaller JS bundle, faster parsing, less memory
Native Animations
Complex animations like page transitions, list scrolling, and gestures run entirely in Dart—no JS overhead.
Minimal App Code
Your JavaScript focuses on business logic. UI complexity is handled by battle-tested Flutter widgets.
Consistent 60fps
State management and rendering optimizations are baked into Flutter, ensuring smooth performance always.
The Best of Both Worlds
By using WebF Native UI components, you get the development speed of web technologies with the performance of native Flutter. Your app code becomes dramatically smaller and simpler—just declarative markup that describes what you want, while Flutter handles the how. This is why WebF apps feel indistinguishable from native Flutter apps.
Performance Comparison
Real-world performance differences between WebF and system WebView solutions.
Page Load Time
Time from navigation to first meaningful paint
Memory Footprint
Base memory consumption per instance
DOM Mutations
Cost of DOM operations during page construction
Frame Consistency
Rendering smoothness during complex animations
Key Advantages
Technical benefits that make WebF fundamentally faster than WebView-based solutions.
Background Initialization
WebF bootstraps JavaScript, builds the DOM, and processes CSS in the background when your app starts.
Technical detail: State is preserved in memory, ready for instant display when the user navigates to the WebF view.
Native-Like Loading
Opening a WebF page feels identical to opening a native Flutter page—because the loading phases are the same.
Technical detail: Only Layout and Paint execute on navigation, skipping JS/DOM/CSS phases entirely.
Unified Widget Tree
Web elements become Flutter widgets, participating in the same rendering pipeline as native components.
Technical detail: No separate browser process, no IPC overhead, no frame synchronization issues.
Persistent State
Navigate between native and web views without losing state. DOM and JS context survive route changes.
Technical detail: Single JS context and DOM tree shared across the entire application lifecycle.
