Rune: A native GPU-rendered Rust UI framework for macOS, Windows, Linux and web

Rune is a native GPU-rendered Rust UI framework that works across macOS, Windows, Linux, and the web, featuring its own renderer, text layout, and animation systems. The framework allows developers to run apps headlessly for testing purposes, such as rendering to PNG and inspecting element trees. It is currently pre-release and available on GitHub, with documentation and examples provided for developers to integrate it into their projects.
