TL;DR

Pick v0 when you need a screen you can click through before a repository exists: it writes Next.js, Tailwind CSS and shadcn/ui code in a hosted sandbox, previews it and deploys to Vercel. Pick Claude Code when the screens belong in a repository you already have, next to your components, rules and tests. You own the code either way, entry plans cost $20 to $30 a month, and many screens stay consistent when each one imports the same component files, which v0 sets up with Design Systems 2.0 and Claude Code with a registry and a rules file.

The v0 vs Claude Code question usually gets answered on one component: a card or a form, generated in a minute. The harder part starts at the third screen. A sign-in page, a pricing page and a settings page belong to one product, so they have to share buttons, fields, spacing and tone, call your real API, and still match after six months of changes.…
