WaterUI
A modern, cross-platform UI framework for Rust that renders to native platform widgets (UIKit/AppKit on Apple, Android View on Android) rather than drawing its own pixels. Build reactive, declarative UIs with Rust's type safety and performance.

What is WaterUI?
WaterUI combines declarative, component-based architecture with fine-grained reactivity to deliver truly native user interfaces across platforms. Unlike traditional Rust UI frameworks that implement custom rendering, WaterUI translates your Rust view tree into platform-native UI components through an FFI bridge, ensuring your apps look and feel native on every platform.
The framework is built on three core principles:
- Native-first rendering: Your UI components compile to UIKit/AppKit views on iOS/macOS and Android View on Android, delivering authentic native behavior and performance.
- Fine-grained reactivity: Powered by the nami crate, UI updates are surgical and automatic—only affected components re-render when state changes.
- Hot reload: Changes to your Rust code reload instantly in running apps via dynamic library swapping, providing a development experience similar to web frameworks.
WaterUI is ideal for building production mobile apps, cross-platform tools, and native desktop applications where performance and platform integration matter.
