GXUI

GXUI is an experimental, cross-platform GUI toolkit for Go that explored what a modern, GPU-accelerated desktop UI could look like for the language. It provided a set of widgets, layout containers, and event models that ran on Windows, macOS, and Linux, targeting a single Go API surface. Rendering was driven by a graphics backend so that animations, text, and compositing could be smooth without relying on heavyweight native bindings. The library encouraged idiomatic Go patterns—composition and interfaces—while offering a retained-mode tree of views for common desktop interactions. Although the project is no longer actively developed, it remains a reference for how to bridge Go’s concurrency model with UI event loops and rendering pipelines. Developers still look to it for examples of input handling, focus management, and custom drawing in pure Go environments.
