Gooey is a hybrid immediate/retained mode UI framework for building fast, GPU-rendered applications on macOS using Metal, Linux with Vulkan/Wayland, and browsers via WebAssembly/WebGPU. It features a component-based layout with declarative UI primitives and supports GPU rendering with MSAA anti-aliasing.

Microsoft's GUI strategy has been inconsistent for over thirty years, leaving developers unclear on the best framework for building Windows desktop applications. Options like WPF, WinUI 3, and Electron create confusion rather than providing a clear direction.

A compile-time UI framework transforms ordinary classes and functions into reactive DOM updates without using a virtual DOM, hooks, or signals. This framework claims to be the fastest compiled UI solution, utilizing classes for stores, components, and getters for computed values, requiring no new primitives for developers to learn.
