UX Power Tools recently announced that it’s new project Themeroll.it is coming soon. They promise to help create a custom design framework for Sketch without pushing a single pixel.
Presumably this service will take advantage of the forthcoming Sketch 43 file format to generate design frameworks without requiring the app itself. Excited to see this in action!
Generate custom design frameworks for #sketchapp without opening Sketch.
