24 alternatives to Protostar – A CLI Prototyping Tool
I am a UX designer who has been asked to help design a CLI. Looking for tools to quickly prototype a CLI that could also be easily shared with colleagues or used for user testing, I couldn't find anything. The only option I could think of was to code something from scratch using one of the existing CLI libraries. To make designing, prototyping and user testing CLIs easier for me in the future, and hopefully to help other designers who are not as comfortable with coding, I have developed this CLI prototyping tool. I would be very interested to hear if this tool would be useful to other people…

I'm Dan, and I built a CLI that lets AI agents design in Figma. What it does: 100 commands to create shapes, text, frames, components, modify styles, export assets. JSX importing that's ~100x faster than any plugin API import. Works with any LLM coding assistant. Why I built it: The official Figma MCP server can only read files. I wanted AI to actually design — create buttons, build layouts, generate entire component systems. Existing solutions were either read-only or required verbose JSON schemas that burn through tokens.
