This is a quick and dirty attempt to use Elm with Sciter. It seem like quite a good match at a first glance to create lightweight native applications for different platforms that are also maintainable.
Elm's virtual dom does not work out of the box but Sciter has a native implementation that can be used with ports. Also XMLHttpRequest needs to be simulated. As an upside, other APIs could also potentially be used with the XMLHttpRequest "hack".
I have not mutch time right now to explorer this further but it seems to be possible to create something useful with a bit of work.
Just build the Elm project in the elm folder with elm make ./src/Main.elm --output elm.js and then use index.html to run with scapp (only tested on Windows 11)
