Ninna UI — A Better Bootstrap Alternative
Upgrade from legacy CSS to modern React components.
Bootstrap served the web well for over a decade, but it was built for a different era. Ninna UI gives you real React components with TypeScript, Radix accessibility, Tailwind CSS v4, and CSS-only theming — no jQuery legacy, no Sass build step.
Why developers switch from Bootstrap
Common reasons developers move from Bootstrap to Ninna UI:
Ready to move from class-based CSS framework to real React components with props and TypeScript
Need Tailwind CSS v4 support — Bootstrap uses its own conflicting utility system
Want built-in accessibility that Bootstrap's JS plugins don't provide
Looking for modern oklch colors instead of Bootstrap's Sass variable system
Prefer tree-shakeable npm packages over Bootstrap's monolithic CSS bundle
