Why we picked it This is the design system a solo technical founder can actually ship with this week, no designer needed. You copy the components into your own codebase (built on Tailwind and Radix), so you own the code, get sensible defaults and accessibility for free, and can tweak spacing, type, and color tokens without fighting a theme engine. It is the honest answer to "do I need to hire a designer yet": for most early products, a good system gets you 80 percent of the way.

- Copy-paste components you own outright, not a locked npm package, so you can customize anything to match your product.
- Accessibility and interaction behavior come from Radix primitives, so you are not reinventing dropdowns and dialogs by hand.
- Tokens (color, spacing, type) live as CSS variables, which is enough of a design system to keep a solo founder consistent while shipping fast.
