Ninna UI - A Better Headless UI Alternative
Styled and themed. Not build-your-own.
Headless UI from the Tailwind team gives you excellent unstyled primitives - but you style every component yourself. Ninna UI ships 67 pre-styled, themed components with Radix accessibility and CSS-only theming. No styling layer to build.
Why developers switch from Headless UI
Common reasons developers move from Headless UI to Ninna UI:
Want styled, themed components out of the box instead of building the styling layer yourself
Need a wider component catalog - Headless UI covers 15+ interactive primitives, Ninna UI has 67 components
Prefer CSS-only theming with oklch presets over manually styling each component
Want to ship faster without designing and implementing a styling layer for every component
Need components beyond interactive primitives - forms, data display, layout, feedback
Is it worth switching?
Headless UI is perfect when you want to own every pixel. The move to Ninna UI happens when you realise you're re-styling the same Dialog and Menu on every project and would rather have that work done for you — with Radix accessibility preserved.
When Headless UI is the better choice
We don't think Ninna UI wins every time. Stick with Headless UI if:
1
You want 100% design freedom and are willing to build the styling layer for every component yourself.
2
You're already on Tailwind and want primitives designed specifically for Tailwind utility classes.
3
You need a very small bundle — only behaviour, no CSS at all.

Switching from Headless UI: FAQ
Why move from Headless UI to Ninna UI?
To stop building the styling layer. If you've been styling Headless UI's Dialog, Menu, and Tab on every project, Ninna UI gives you the same accessibility with theming already done — and 50+ additional components Headless UI doesn't ship.
Can I keep some Headless UI components?
Yes — Headless UI and Ninna UI components coexist fine in a React app. Migrate the ones where building the styling layer isn't worth it.
Do I lose design freedom?
Some — Ninna UI ships with a default visual design. You customise through data-slot CSS targets and className overrides rather than building from scratch. It's less work but also less control.
