Ninna UI - A Better shadcn/ui Alternative
Stop copy-pasting components. Start shipping.
shadcn/ui makes you responsible for every bug fix and update. With Ninna UI, you get the same Radix accessibility and Tailwind styling through standard npm packages - updates arrive automatically, not through manual re-copying.
Why developers switch from shadcn/ui
Common reasons developers move from shadcn/ui to Ninna UI:
Tired of manually merging component updates after every shadcn release
Want automatic bug fixes delivered through npm update instead of copy-paste
Need oklch perceptual colors instead of manual HSL CSS variable management
Prefer a managed library that still offers deep customization via 98 data-slot CSS targets
Looking for a cleaner dependency tree - Ninna UI wraps Radix internally so you never manage peer deps
Is it worth switching?
If your shadcn/ui folder has quietly drifted from upstream and every `npx shadcn add` now means a merge conflict, that's the exact pain Ninna UI removes. You keep Radix accessibility and Tailwind styling, but updates become boring again.
When shadcn/ui is the better choice
We don't think Ninna UI wins every time. Stick with shadcn/ui if:
1
You want to read and edit every line of a component's source directly in your repo, with no library abstraction in the way.
2
You're still on React 18 — shadcn/ui supports it today, while Ninna UI targets React 19+.
3
You're already deep into the shadcn ecosystem (registries, community blocks) and the switching cost outweighs the maintenance savings.

Switching from shadcn/ui: FAQ
How hard is it to migrate from shadcn/ui to Ninna UI?
Most components map one-to-one. You replace copy-pasted files with package imports, delete components.json, drop the Radix peer dependencies, and swap your manual CSS variables for a single theme import. Your existing Tailwind utility classes keep working.
Will I lose the ability to customise components?
No. Instead of owning the source, you customise through 98 data-slot CSS targets and the cn() helper. You give up direct source edits in exchange for never having to manually merge upstream fixes again.
Do I have to migrate everything at once?
No. Ninna UI components and shadcn/ui components can coexist in the same app since both are just React + Tailwind. Migrate page by page.
