Nex UI

NexUI is an open-source set of 50+ accessible React components built with Tailwind CSS v4 and React 19, following the shadcn/ui copy-paste model but with no Radix, Headless UI or other primitives underneath. Components cover auth flows with OAuth and 2FA, chat, data views, charts, forms and carousels, and a small CLI scaffolds a config and copies files into components/ui. Start with the auth components, whose sign-in, sign-up and multi-step flows show the 2FA and password-strength handling it builds without primitives.
