UI & Design
The go-to for admin panels and internal dashboards — dense tables and forms out of the box, at the cost of looking like one.
A newer, hooks-first component library with better defaults and fewer footguns than most — an indie-hacker favorite for solo builds.
The old reliable of React component libraries — batteries-included Material Design components for shipping a finished-looking app fast.
Unstyled, accessible component primitives quietly powering shadcn/ui and a good chunk of the polished apps you use every day.
You don't npm install it — you copy the code into your repo and own it, which is why it became the default start for new React UIs.
Build and test UI components in isolation before wiring them into your app, so broken states and visual regressions get caught early.
