Superdesign is an open-source AI design agent that lives inside your code editor (VS Code, Cursor, Windsurf, Claude Code). Generates UI mockups, wireframes and reusable components as real React/Tailwind/CSS code, reading your existing design system first so output matches your conventions.
Free tier available. Pro is a flat $20/month: deliberately flat-rate rather than usage-based credits, so heavy iteration doesn't quietly run up a bill the way competitors' credit systems can.
Design engineers and developers who want AI-generated UI without leaving their code editor, and want output that respects an existing codebase's design system instead of generic styling.
The Flash Wireframe feature (roughly ten design directions in seconds) is worth using early in a project to explore options fast, before committing to one direction for full-fidelity generation.
Context-aware AI product designer.
