Tremor vs Ninna UI
React components specifically designed for building dashboards. Compare Tremor and Ninna UI side by side to find which React component library fits your project in 2026.
Quick Verdict
Tremor is the best-in-class choice for dashboard-specific React components — charts, KPIs, sparklines, and metrics built on Recharts and Tailwind. If your app is analytics-heavy, Tremor fills a gap that general-purpose libraries don't. Ninna UI covers the rest of the application — forms, navigation, overlays, settings — with 67 components and CSS-only theming. Using both is a common pattern.

Tremor vs Ninna UI: FAQ
Does Ninna UI have chart components like Tremor?
No — Ninna UI focuses on general-purpose UI components (forms, navigation, overlays, data display). For charts and dashboards, Tremor or a charting library like Recharts is the better choice. The two libraries complement each other.
How does theming compare?
Tremor uses Tailwind config customisation. Ninna UI uses CSS-only theming with oklch presets — one import, no config. If you use both, scope Ninna UI's theme to the non-dashboard parts.
Is Tremor on Tailwind v4?
Tremor is currently on Tailwind v3 with v4 support in progress. Ninna UI is built natively on Tailwind v4's CSS-first configuration.
