All interactive tools run entirely in your browser. Your data never leaves your device.

How It Works

Define your design tokens by adding variables with names, values, and categories. The tool generates CSS custom properties, SCSS variables, or JSON output with optional category grouping and namespace prefixes.

Features

  • 4 token categories: colors, spacing, typography, custom
  • 3 output formats: CSS custom properties, SCSS variables, JSON
  • Category grouping: organize output with section comments
  • Namespace prefix: auto-prefix variables (e.g., --app-*, --theme-*)
  • Custom selector: use :root, body, or any selector
  • 6 presets: Material Design, Tailwind spacing, Typography scale, Dark/Light theme, Minimal
  • Statistics: total variables, per-category counts
  • Private: runs entirely in the browser — no data transmitted
