Ninna UI - A Better Preline UI Alternative
TypeScript components. Not HTML templates.
Preline UI provides HTML templates with vanilla JS plugins - no React components, no TypeScript, basic accessibility. Ninna UI gives you 67 real React components with type-safe props, Radix ARIA compliance, and CSS-only theming.
Why developers switch from Preline UI
Common reasons developers move from Preline UI to Ninna UI:
Building a React app and need real component APIs instead of HTML template copy-paste
Want TypeScript type safety - Preline has no TypeScript types at all
Need proper accessibility - Preline has basic ARIA support only
Prefer component-level props and events over vanilla JS event handling
Looking for oklch perceptual colors and CSS-only theming without a Tailwind plugin
Is it worth switching?
Preline is handy for static Tailwind markup; the switch to Ninna UI happens when a project becomes a typed React app that needs real components instead of HTML plus a JS enhancer.
When Preline UI is the better choice
We don't think Ninna UI wins every time. Stick with Preline UI if:
1
You want copy-paste Tailwind HTML usable in any stack, not React components.
2
You're building static pages or using a non-React framework.
3
You like Preline's extensive template/snippet catalog.

To get typed React components and built-in accessibility instead of HTML snippets driven by a separate JS plugin.

You'll replace HTML snippets with Ninna UI components, but Tailwind utility classes carry over.
