I've recently heard about Knete through : <https://github.com/karaxnim/karax/pull/185> which is an experiment of using Nim without using a VDOM: <https://github.com/karaxnim/karax/blob/master/experiments/trello/knete.nim>
In non-Nim world: <https://github.com/davedawkins/Sutil> which is also Svelte inspired. As far as Svelte being simpler and more productive than React, I'd say that depends on person and what they like. But what Svelte does really right is that interactive guide which is amazing. Lastly, ofcourse I'd like to see Karax evolve into something more intuitive and faster, but with limited resources I'd rather have incremental small changes to Karax than adapting to a totally new framework. Good documentation( <https://github.com/karaxnim/karax/pull/199> ) will help Karax currently more than anything IMO.
