Tauri is an Electron alternative for building desktop applications using a combination of Rust tools and HTML, CSS, and JavaScript rendered in System's WebView. Unlike Electron which bundles Chromium, the applications built with Tauri leverage the underlying WebView, that is, WebKit on macOS, WebView2 on Windows and WebKitGTK on Linux. This approach has interesting trade-offs — on one hand you get small and fast application binaries; on the other hand, you need to verify compatibility quirks across WebViews of different systems.
