Components AI

An open-source, code-free studio for building parametric and generative design systems

Parametric generative components

Adjust parameters, lock the ones you like, and cycle through generated design variations until the result fits.

Theme import from any site

Point the tool at an existing website and it parses CSS for colors, typography, motion, shadows and spacing as design tokens.

Accessible color and type systems

Dedicated generators for contrast-checked color scales, responsive type scales and layered box shadows.

Multi-format export

Export designs as React, JS, JSX, JSON, SVG, PNG, HTML, CSS, CSS custom properties or Sass.

Strengths & Pros

+Genuinely constraint-driven: components stay tied to tokens instead of drifting
+Theme import from an existing site is a fast way to start with real brand values
+Very broad export list, so output fits most front-end stacks
