Freya is a cross-platform native GUI library for Rust that uses a declarative component model to build desktop and mobile applications.

Freya addresses the need for a native, performant GUI framework in Rust by combining a declarative component architecture with automatic re-rendering based on state changes. Components can maintain internal state or subscribe to shared state, and the framework provides built-in components ranging from simple controls like Button and Switch to complex widgets such as VirtualScrollView, Calendar, and ColorPicker. The library supports smooth animations for colors, sizes, and positions with full control over timing and easing functions. It also includes rich text editing capabilities with cursor management, text selection, and keyboard shortcuts, plus a code editor component that uses tree-sitter for syntax highlighting and supports custom grammars.

Freya suits developers building cross-platform applications who want to write native UIs in Rust without sacrificing performance or native feel. It targets both desktop and mobile platforms and works well for projects requiring rich interactive components or text editing functionality. The framework requires setting up a development environment and uses git submodules, so cloning must include the `--recurse-submodules` flag to avoid compilation failures in examples.

The project shows active development with regular commits and ongoing refinement of its component library and animation system. The codebase maintains examples demonstrating each major feature, from basic components to advanced animations and code editing. Development includes attention to platform-specific issues, such as documented workarounds for Windows GNU toolchain compatibility. The project maintains public communication channels and documentation resources for users exploring adoption.
