How about some screenshots?
Its very difficult to compare X to Y anywhere on this site. Its just an aggregator, not really an exemplary resource.
It looks like it just grabbed the intro to each project's self-description, but blurbs like "Zero-cost ultra-high-performance declarative DOM library using FRP signals" would be worth very little even with screenshots.
Cosmic DE is built using iced which is a rust gui library. As far as native, single-platform guis go, I'd say rust is plenty mature.
There's also Bevy, a rust game engine, which, if I'm not mistaken is built on egui(?), and I think supports multiple compile targets.
Between a desktop environment and a game engine, I'd say rust is in a pretty decent place when it comes to gui.
Not entirely correct, they have bevy_ui as the in-house example but many people use the third party bevy_egui crate
Saying “almost” or “yes” privileges the activity and hype around Rust GUI over actual results. Bevy is the ironic example: a game engine that produces more discussion and code than, so far, one notable & good game.
The best primer on the current(ish) state of GUI programming in Rust, IMO, is this article from 2025 which is linked on that page: https://www.boringcactus.com/2025/04/13/2025-survey-of-rust-...

Yes, seeing how simple it seems to redirect to a page playing the sound, instead. ;)
At most it could give you an idea about whether some widgets are supported, but even there a list you could filter frameworks by would be worth a thousand screenshots
Not everybody works in big tech.
