A complete, unminified Next.js 16 (App Router) + React 19 + TypeScript QR code generator you own outright — 74 source files, every one editable. Glassmorphism dashboard, live QR preview that updates as you type, true-millimetre A4 print sheets, and PNG export up to 4096 px. Deploys to Vercel or Netlify in about ten minutes, or runs locally with npm install && npm run dev. Branding, accent colours and background gradient are single-variable edits documented in the README. Built for developers who need a working QR generator in a client project this week rather than a weekend of npm archaeology, and for agencies who bill for a "custom QR solution" and need something solid to customise. Styled with Tailwind CSS 4 and shadcn/Radix UI components. No database, no backend, no API keys — it runs anywhere Node 18+ runs.
