That's really nice. It would be really good for game GUIs too where the situation is quite poor and would work well with underlays/overlays/worldspace UIs. That said while binary size may be around 10mb, it still baloons to 500mb at runtime for your TODO list example which is more than some electron apps.

Yeah, the RAM usage is quite high atm. The good news is that it's almost all the rendering layer (WGPU+Vello). So if we can make the renderer more efficient then it's likely we can bring that down. There is also some low hanging fruit in the DOM implementation (but I think that's only actually causing a few 10s of MB of usage).

I would also note that native toolkits (SwiftUI, etc) tend to also use at least ~100mb RAM these days. A lot of that is unavoidable if the app is actually visible, due to modern screen resolutions being so high.
