# Next.js + shadcn/ui Starter V0 Template: Your Blank Canvas with Batteries - Tool: V0 Templates - Last updated: July 2026 ## TL;DR The Next.js + shadcn/ui Starter is the blank canvas v0 template: Next.js 14+ App Router, TypeScript, Tailwind CSS, and a complete shadcn/ui component setup pre-configured. Dark mode via next-themes, Geist font via next/font, and all CSS color variables ready to override. Fork it as your starting point for any new project — then use the prompt pack to add pages, auth, and a database without touching the config yourself. ## Frequently asked questions ### Is this Next.js shadcn/ui starter template free? Yes. V0 community templates are free to fork with a free V0 account. You can use the code in personal and commercial projects without any licensing restrictions. ### Can I use this boilerplate for a commercial SaaS product? Yes. There are no commercial-use restrictions on V0 community templates. You own the forked code and can ship it as a paid product. ### Why does my dark mode flash the wrong theme on first load? This is a known next-themes + Next.js SSR interaction. Add suppressHydrationWarning to the html element in app/layout.tsx. See the gotcha above for the exact fix prompt you can paste into V0 chat. ### Why does my fork break in the V0 preview after I add a package? V0's esm.sh preview sandbox cannot load some packages — particularly those that access browser APIs during SSR, use native Node.js modules, or reference the shadcn registry at a URL that has changed. Deploy to Vercel to test packages reliably. Use 'Fix with v0' on build errors before deploying. ### How do I connect a database to this starter? Add your Supabase environment variables (NEXT_PUBLIC_SUPABASE_URL, NEXT_PUBLIC_SUPABASE_ANON_KEY) in the V0 Vars panel, then paste the Supabase user profiles prompt from the prompt pack above into V0 chat. It scaffolds the table, RLS policies, and a profile page as a Server Component. ### What is the difference between this starter and the Sidebar Layout template? This starter is a minimal blank canvas — just Next.js, shadcn/ui config, dark mode, and a font. The Sidebar Layout template is a pre-built nav shell with a collapsible sidebar, TopBar, and MainContent sections. Start here if you want full control; start with Sidebar Layout if you need a multi-page app navigation structure right away. ### My NEXT_PUBLIC_ env vars are undefined after deploying to Vercel. Why? NEXT_PUBLIC_ variables are baked into the JavaScript bundle at build time. If you added them to Vercel after the last deployment, you need to trigger a new deployment (not just a redeploy from cache) for them to take effect. See the gotcha section above. ### Can RapidDev help extend this starter into a production app? Yes. RapidDev takes V0 starters and adds production-grade auth, database schemas, CI/CD pipelines, and design system alignment.
