What is Rune?
Rune is a native user interface framework written in Rust. It provides its own rendering engine, text handling, layout system, and animation springs. The framework supports building applications for macOS, Windows, Linux, and the web.
A key feature of Rune is its headless execution mode. Applications built with Rune can run without a display server, allowing them to render directly to PNG images, export their element tree, and accept scripted input. This design makes it suitable for automated testing and AI agent workflows.
The project is currently in pre-release. Developers are advised to pin a specific revision from the dev branch, as the main branch is rewritten frequently. The code is licensed under MIT and hosted publicly on GitHub.
