  "what": "35+ chart and dashboard components built on Recharts and Radix, copy-paste, requiring React 18.2+ and Tailwind v4. Tremor Labs was acquired by Vercel in Jan 2025 and the previously-paid Blocks were released free under MIT.",
  "why": "If your project has an internal editorial dashboard — traffic per article, submission pipeline, subscriber growth over Supabase queries — this is the strongest free option and much better than hand-rolling Recharts.",
  "warn": "<b>There are two Tremors.</b> The legacy npm package <code>@tremor/react</code> still has an unresolved Tailwind v4 bug (renders completely unstyled). Use the copy-paste components from the site; do not npm install the package.",
