Meta is testing a big change for WhatsApp on Windows 11: the latest beta replaces the native WinUI-based desktop app with one built on WebView2. That means WhatsApp would embed web content using Microsoft’s WebView2 runtime (essentially a built-in browser view) rather than relying on WinUI, the framework used to build native Windows interfaces.
What this change means
- Unified codebase: Moving to WebView2 would let Meta reuse more of WhatsApp’s web code across desktop platforms, simplifying development and updates.
- Easier cross-platform distribution: A WebView2 approach can speed feature parity between Windows, macOS (via similar web wrappers), and other desktop environments.
- Faster release cycles: Fewer platform-specific UI changes may make it easier to roll out and maintain new features.
Performance trade-offs
Early tests indicate the WebView2 beta may use significantly more memory — reports suggest up to around 30% more RAM compared with the current WinUI app. That extra memory usage can matter on systems with limited RAM or when many apps run at once. CPU and battery impact will depend on how Meta optimizes the WebView2 wrapper over time.
What users should know
- If you prefer lower memory use and a truly native Windows feel, you may want to wait before switching to a WebView2-based build.
- If you already use WhatsApp Web in your browser, the WebView2 app will feel familiar since it’s essentially the same web experience wrapped for the desktop.
- Installing beta versions can expose you to bugs and higher resource usage; use beta channels only if you’re comfortable testing and reporting issues.
What Meta likely gains
Meta’s move would reduce duplicate engineering effort, speed cross-platform feature rollouts, and centralize bug fixes. Over time, optimization could narrow the memory gap, but for now the trade-off is clearer: simpler maintenance and faster updates versus higher RAM use.
