My understanding is that Tauri allows building the presentation layer with standard web tech (HTML, CSS, JS) while using the system web view to render it. This has the major benefit over Electron that you don't have to ship all of Chrome in your binary. The downside is that now you have to support the peculiarities of the system web view (Safari, Chrome, Firefox, etc.)
There is another benefit+downside: Web view can get security updates without you updating your software. But, that means your app might break at some point even if you haven't released any updates.
