How to use v0 by Vercel: sign in, prompt UI, export to Next.js

v0.dev login, prompt a UI block, copy or export to Next.js.

v0 by Vercel is a browser UI generator: describe a component in plain language, preview it, then copy the code or send it to a Next.js project linked on Vercel.

The query is how to use v0 to generate UI and export to Next.js. This page follows sign-in, prompting, and export flows on v0.dev and Vercel docs. For designers, PMs, and front-end devs who can reach v0.dev. To review a layout on a short call, open wbmeet; see create and join a room.

What v0 is for

v0 outputs React snippets with Tailwind CSS and common shadcn/ui patterns—not a full CMS site. Use it for landing sections, dashboard cards, forms, and empty states. You get an interactive preview in v0; when satisfied, use Copy code or Vercel’s add to codebase / deploy entry (labels vary by UI) to land an App Router Next.js project. Credits and billing show in your v0/Vercel account.

Sign in on v0.dev

  1. 1

    Open v0.dev

    Visit https://v0.dev (or the domain Vercel docs list today). Click Sign in / Log in—never sideload an “offline v0” bundle from unknown mirrors.

  2. 2

    Authenticate with Vercel

    Use GitHub, Google, or email to sign into your Vercel account—the same identity you use to deploy Next.js. Team seats need permission; enterprise SSO follows admin policy.

  3. 3

    Check credits and GitHub access

    After login, read free-tier limits and daily generations on the account or pricing page (numbers change—trust the UI). If you plan GitHub export, stay signed into GitHub and approve the scopes Vercel/v0 request.

Generate your first UI block

  1. 1

    Specify layout, states, and stack

    Be concrete: “Responsive SaaS pricing table, three tiers, highlight middle column, Tailwind + shadcn Card, dark-mode friendly.” Mention empty/loading/error copy if needed. Avoid asking for twenty pages at once.

  2. 2

    Iterate in the preview

    v0 renders a clickable preview. Follow up with focused edits: “Use outline CTA,” “Stack to one column on mobile.” Change one concern per message so versions stay comparable.

  3. 3

    Lock a version before export

    Pick the preview you want, then copy or export. Click primary buttons and tabs in preview first; generated forms and a11y often need human follow-up.

Prompts should be testable

“Two columns desktop, one column mobile, primary #0b5cff” beats “make it prettier.”

02

Export ≠ production-ready

Verify aria-labels, focus order, and real API wiring—v0 gives a UI starting point.

03

Pair with IDE agents

v0 excels at UI blocks; wire logic and tests in Cursor, Continue, etc.—see our related notes.

Suggested flow: sign in at v0.dev → one small UI prompt → iterate in preview → copy or export Next.js → npm run dev locally → optional huddle for stakeholder sign-off.

Vs Cursor / Continue
v0 is browser UI generation; local agents: Cursor CLI, Continue.
Must deploy on Vercel?
Copied code runs on any Next host; Vercel export is convenience, not a lock-in requirement.

Questions worth checking

Can I use v0 without a Vercel account?

Official sign-in uses the Vercel identity system. Register with a real email or GitHub; credits follow v0’s account page.

Project errors after paste?

Often missing shadcn components or Tailwind plugins. Install deps from v0’s output notes; match @/ to tsconfig paths.

Non-Next project?

Yes, with import/route edits. React + Vite works; official export templates skew toward App Router.

GitHub blocked at work?

Use Copy code into an internal repo only. You may still need v0.dev access—follow IT policy.
