There's some early work for Ubuntu here [1]. You can also currently use React to share code across iOS [2], Android [3], UWP [4], macOS [5], web [6], VR [7] and a bunch of other stuff that is there mostly for fun (like React Hardware [8] and React Sketch.app [9]). There's also experimental work on defining a set of primitives that works across all of these platforms [10].
