Ninna UI — A Better Mantine Alternative
Fewer moving parts. Same results.
Mantine is powerful but complex — MantineProvider, PostCSS setup, createTheme(), and a sprawling API. Ninna UI delivers 69 focused components with one CSS import. No providers, no PostCSS, no learning curve.
Why developers switch from Mantine
Common reasons developers move from Mantine to Ninna UI:
Overwhelmed by Mantine's API surface and package count
Want Tailwind CSS v4 native support instead of PostCSS-based styling
Need simpler theming — one CSS import vs JavaScript createTheme() configuration
Looking to reduce bundle size by dropping PostCSS and JS theming runtime
Prefer a focused component set over a monolithic library
