This might be my first post on this forum as I've been more active on Reddit, but I'd like to self-nominate Maycoon. It's a UI framework I've been developing over the last year.
It uses vello for vector graphics which itself uses wgpu as a graphics backend. I recently made some dramatic changes to state management and as of now, it uses signals for local state management.
Might not be as mature as other projects listed here, but worth a try
