Design systems
How Once UI compares to libraries and styling approaches for React and Next.js.Tailwind CSS
Tailwind CSS revolutionized utility-first styling. Once UI takes a component-first path built specifically for Next.js — same goal of shipping fast, different abstraction.vs
shadcn/ui
shadcn/ui changed how developers think about component libraries — copy the source, own the code. Once UI is the opposite trade-off: install one package, one config, one syntax across every screen.vs
Radix UI
Radix UI provides excellent unstyled, accessible primitives. Once UI provides styled, composed components — and the pages around them.vs
HeroUI
HeroUI (formerly NextUI) is a polished React component library built on Tailwind and React Aria. Once UI is an open-source Next.js design system with its own styling layer and Pro templates.vs
Mantine
Mantine is one of the most complete React component frameworks — hooks, forms, dates, rich components. Once UI is narrower and deeper for Next.js marketing sites, dashboards, and indie SaaS.vs
Base UI
Base UI from MUI is a set of unstyled, accessible React components — the successor spirit to Radix for MUI users. Once UI is a fully styled design system with Next.js templates.vs
