Gooey: A GPU-accelerated UI framework for Zig

TL;DR

Gooey is a new GPU-accelerated UI framework for Zig, supporting macOS, Linux, and WebAssembly. It offers modern features like declarative UI, animations, and native platform integrations. The project is in early development, with ongoing API evolution.

Gooey, a new GPU-accelerated UI framework for Zig, has been publicly announced, supporting macOS, Linux, and WebAssembly, with ongoing API development. The project aims to bring modern, high-performance UI capabilities to Zig developers across platforms.

The Gooey framework is designed to leverage GPU rendering via Metal on macOS, Vulkan on Linux, and WebGPU on the web, providing hardware-accelerated UI performance. It includes features such as declarative, component-based layout, a separation of concerns between UI and state management, built-in animations, and support for native platform features like file dialogs, clipboard, IME, and accessibility.

Built entirely in Zig with zero external dependencies, Gooey links against system frameworks and libraries, ensuring lightweight and portable builds. Its API is currently in early development, with the team actively soliciting feedback via a Discord community. Several demo applications, including a todo app and a space dashboard, showcase its capabilities.

Why It Matters

This development matters because it introduces a modern, GPU-accelerated UI toolkit for Zig, a language gaining popularity for systems programming. It enables high-performance, cross-platform UIs with advanced features, potentially impacting how applications are built in Zig and related ecosystems. The project could fill a gap in Zig’s tooling for GUI development, which has been historically limited.
