Convergence UI

Convergence UI is a live theme editor and toolkit for Tailwind v4 and React apps: a floating editor lets you change OKLCH colour tokens, typography, borders and radius on running shadcn/ui components and watch them update. Behind it sits a headless engine that reads, validates, imports and exports themes, checks contrast, renders theme CSS during SSR for Next.js and supports per-component overrides. Each token in its palette names the role it maps to, such as --destructive for danger notifications and deletion confirmations.
