Design System
Change once, update everywhere
Colors, fonts, text styles, buttons, spacing and container width in one place. Every widget — and every page your AI builds — uses them, so a rebrand is one prompt away.

With your AI
Or just ask
Everything here is something your AI can do for you through Uncoder’s MCP server.
Ask your AI
“Use #1F3A2E as the primary color and #B5623C as the accent, Fraunces for headings and DM Sans for text.”
Ask your AI
“Make all buttons pill-shaped with a subtle lift on hover.”

Brand
Colors and fonts as variables
Name your brand colors and fonts once. Widgets refer to them, so changing a color changes it everywhere — and the AI can only pick from your palette.

Typography
Text styles that scale
Display, H1–H6, lead, eyebrow and small styles with sizes per device. Pick a style instead of setting fonts on every heading.

Dark mode
Dark mode, built in
Give each color a dark value and add the Color Scheme Switch widget. Visitors choose; their device preference is the default.
