v0
v0 is Vercel's AI UI generator — describe a component or page, get shadcn/ui + Tailwind React code you can copy into your app.
Last reviewed: June 2026
v0 pricing, export formats, and model backends change. Verify at v0.dev before team rollout.
What it is good at
| Strength | Detail |
|---|---|
| UI scaffolding | Forms, dashboards, marketing sections from prompts |
| shadcn/ui + Tailwind | Matches common Next.js stack defaults |
| Iteration in chat | Refine layout and copy before export |
| Design exploration | Faster than hand-coding first draft |
Setup
- Sign in at v0.dev with Vercel account
- Describe UI with stack constraints: "Next.js 15, shadcn, dark mode"
- Export code → paste into your repo
- Run lint, fix imports, wire real data and auth
v0 output is a draft — not production-ready without review.
Modes / core workflow
| Step | Action |
|---|---|
| 1 | Prompt with component scope — one screen or widget |
| 2 | Review generated accessibility (labels, focus) |
| 3 | Export; align with your design tokens |
| 4 | Replace mock data with API hooks |
| 5 | Verify — lint, test, visual QA |
When to use it vs alternatives
| Choose v0 | Choose something else |
|---|---|
| Marketing pages, admin UI mockups | Cursor Agent — full-stack feature in existing repo |
| You already use shadcn | Bolt.new — full-stack sandbox (verify current offering) |
| Designer-dev handoff | Human Figma — brand-critical UI |
Not a replacement for Prompting for Code in an existing codebase.
Limitations
- Generic patterns may not match your component library
- Auth, data fetching, and error states need manual wiring
- Accessibility and i18n require human pass
- Licensing — confirm Vercel terms for commercial use
