Avalonia renders through Skia compiled to WebAssembly, so every pixel is under your control.
Text stays razor-sharp on high-DPI screens, animations stay smooth, and layout fidelity matches desktop builds. Users see a native-quality interface without a plug-in or heavyweight JavaScript framework.

Switch on AOT and turn your C# into native WebAssembly before you ship.
Heavy computations run directly on the browser’s WebAssembly engine instead of an IL interpreter, delivering dramatic throughput gains for CPU-bound workloads .
The trade-off is a larger initial download, but CDN edge caching and Brotli compression keep first-paint times brisk.

When you need to tap browser APIs like WebGL, WebUSB, or IndexedDB, simply call straight from C# through the standard JS interop layer.
Keep business logic in managed code while borrowing the web platform only where it shines, all without leaking global variables or wrestling with TypeScript build chains.

Your application arrives as static files that any modern browser can load. No Electron runtime, no WebView wrapper, no security prompts.
Serve from GitHub Pages, S3, Azure Static Web Apps or behind a corporate firewall; if the user can reach HTTPS, they can run your software.

A single static deployment bundle is all you ship.
Drop it on a CDN or behind a reverse proxy and every user is on the latest version the moment they refresh.
No installers, no update daemons, no native permissions headaches.
