Describe the Component, Not Just the Vibe
"Make it look modern" gets you generic output. Specify structure and behavior: "a pricing section with three tiers, the middle one highlighted, monthly/annual toggle, and a feature comparison list." The more concrete the spec, the closer the first generation lands to what you need.
Iterate in Small Steps
v0 keeps a conversation per generation, so refine incrementally: "make the cards equal height", "add a hover lift", "use our brand blue for the CTA". Small, targeted follow-ups produce cleaner results than rewriting the whole prompt — and you can branch from any earlier version.
Give It Your Design Context
Provide your color tokens, font, and any existing component conventions up front. You can attach images or screenshots to match an existing look. The closer the input is to your real design system, the less reskinning you'll do afterward.
Generate for the Stack You Actually Ship
v0 targets React + Tailwind + shadcn/ui by default, which drops cleanly into Next.js apps. If your stack differs, say so and treat the output as a high-quality reference to port, rather than paste — the structure and Tailwind classes still save time.
Review for Accessibility and State
Generated UI looks right but often needs a pass for real-world concerns: keyboard focus, ARIA labels, loading and empty states, and wiring to real data. Use v0 for the visual scaffold, then add the behavior and a11y that production demands.
Treat v0 output as a generated draft: read the code, remove what you don't need, and integrate it deliberately. Pasting large blocks unread leads to dead props, unused imports, and inconsistent patterns.
Extract Reusable Pieces
When a generation includes a button or input you'll reuse, lift it into your own component library instead of duplicating it across pages. v0 is great at producing variety; consistency is your job.
Frequently Asked Questions
What does v0 generate?
Primarily React components styled with Tailwind CSS and shadcn/ui, designed to drop into Next.js and similar apps. It can produce full sections and simple pages from a prompt.
Can I use v0 with a non-React stack?
Its native output is React/Tailwind. For other frameworks, use the generation as a visual and structural reference to port, which still saves significant time.
Is the output production-ready?
It's a strong visual starting point. Plan a pass for accessibility, loading/empty states, and data wiring before shipping.
