There are Deno bindings for webview. https://github.com/webview/webview_deno

I have had a quick play around with it - seems functional. Usual caveats about cross-platform webview apply, but I don't see those as major blockers these days unless you are doing something particularly fancy/niche

I love that you can just run the examples by copy-pasting a command and everything is auto-downloaded via Demo's modules. No installation or huge separate binary downloads. Awesome stuff.
