Recent honorable mention:
Crux - "Cross-platform app development in Rust" - github.com/redbadger/crux
Why? - From the repo:
Shared Core for Behavior - Crux helps you share your app's business logic and behavior across mobile (iOS/Android) and web — as a single reusable core built with Rust.
Thin Shell for UI - Crux recognizes that the best experiences are built with modern declarative frameworks such as SwiftUI, Jetpack Compose, React/Vue, or a WebAssembly based framework (like Yew) — however, it aims to keep this UI layer as thin as it can be, with all other work done by the shared core.
