Gooey, a GPU-accelerated UI framework for Zig, has been announced, supporting multiple platforms with advanced features like GPU rendering, declarative UI, and animations. The project is in early development, with API evolving.
Gooey, a GPU-accelerated user interface framework for the Zig programming language, has been publicly announced as an early development project supporting macOS, Linux, and WebAssembly. The framework aims to enable high-performance, cross-platform UI development with features like GPU rendering, declarative layout, and native platform integrations.
The project, shared on Hacker News, is currently in early development with an evolving API. It supports GPU rendering via Metal on macOS, Vulkan on Linux, and WebGPU on browsers, although WebAssembly support is temporarily blocked upstream on Zig 0.16. Gooey offers a component-based, declarative UI system with primitives similar to flexbox, along with a separation of concerns between state management (Cx) and UI layout.
Key features include built-in animation support, an entity system for dynamic UI elements, retained widgets like TextInput and Checkboxes, and native platform support for images, SVGs, file dialogs, clipboard, IME, and accessibility. The framework is designed to be dependency-free, linking only against system libraries, and does not rely on external Zig packages. Sample applications demonstrate its capabilities, including a todo app, animation demos, and complex dashboards.
Why It Matters
This announcement is significant because Gooey aims to bring GPU-accelerated, high-performance UI development to Zig, a language gaining popularity for systems programming. Its cross-platform support and modern features could make it a valuable tool for developers seeking efficient, native-like UIs in Zig, potentially influencing UI development practices in the language community.

Background
Gooey’s development aligns with a broader trend toward leveraging GPU acceleration for UI rendering, similar to frameworks in other languages but distinct in its focus on Zig, which is known for systems-level programming. The project is in early stages, with ongoing API changes and community involvement through Discord. Prior to this, Zig has had limited dedicated UI frameworks, making Gooey a notable addition aimed at high-performance, native UI development.
“Gooey is designed to be a GPU-accelerated UI framework for Zig, supporting Metal, Vulkan, and WebGPU, with a declarative, component-based architecture.”

What Remains Unclear
It remains unclear how stable the current API will be, as it is described as evolving. WebAssembly support is temporarily blocked upstream on Zig 0.16, which may affect cross-platform deployment. The full feature set and performance benchmarks are still to be established as development continues.
What’s Next
Next steps include stabilizing the API, expanding platform support, and gathering community feedback through Discord. Developers can expect more documentation, tutorials, and sample applications as the framework matures. Monitoring the project’s GitHub repository and Discord will be essential for updates.
Key Questions
What platforms does Gooey support?
Gooey supports macOS (Metal), Linux (Vulkan), and WebAssembly (WebGPU). Support for WebAssembly is currently limited due to upstream issues with Zig 0.16.
Is Gooey production-ready?
No, Gooey is in early development with an evolving API. It is intended for experimentation and early use, not yet for production deployment.
What are the main features of Gooey?
GPU-accelerated rendering, declarative UI, component-based layout, animations, entity system, native platform integrations (images, dialogs, clipboard), and accessibility support.
How can I get involved or try Gooey?
Developers can join the Gooey Discord for updates, contribute to the project, and try the sample applications by building with Zig 0.16+ from the project’s repository.
Will Gooey support other platforms in the future?
Future support depends on community interest and development progress, but expanding platform compatibility is a goal as the project matures.
