Shaper is an interactive design tool that allows users to visually customize and explore UI design systems by adjusting core variables like typography scale, spacing units, color hues, and border radii. Through its minimalist interface, designers can fine-tune properties like font size increments, button proportions, accent hues, and control styles in real-time, giving immediate feedback in a demo layout below the controls. The tool is particularly useful for experimenting with visual consistency and modular scale in user interface systems, helping designers understand how foundational decisions affect the overall aesthetic and usability.
One of Shaper’s standout features is the ability to randomize all values for inspiration or quickly toggle between light and dark modes. It provides live previews for each adjustment, ensuring that design choices are contextualized. Rather than functioning as a full design editor, Shaper serves as a design exploration playground—ideal for prototyping style systems or developing foundational UI design tokens. It’s accessible directly in the browser with no login required, and the project is open-source, making it a practical tool for both learning and early-stage design system planning.
