What Is v0?v0 是什么？
v0 (v0.dev) is Vercel's AI interface generator. Type a prompt — or upload a screenshot or Figma design — and v0 produces a polished, production-quality interface as React + Tailwind CSS + shadcn/ui code that professional developers will actually ship.v0（v0.dev）是 Vercel 出品的 AI 界面生成工具。输入一句话描述——或上传截图、Figma 设计稿——v0 即生成精美、生产级的界面，代码栈为 React + Tailwind CSS + shadcn/ui，是专业开发者真的敢上线的代码。
The workflow is Vercel-native: refine the result in a visual design mode without going back to prompts, sync to GitHub so the code lands in your repo, and deploy to Vercel in one click. Image-to-code and Figma import make it a natural design-to-code handoff tool for teams.整个工作流是 Vercel 原生的：在可视化设计模式里直接微调结果，不用反复改提示词；同步到 GitHub让代码落进你的仓库；一键部署到 Vercel。截图转代码与 Figma 导入，让它成为团队设计稿转代码的顺手工具。
Since February 2026, v0 bills by tokens: each plan includes monthly credits, and generations draw down credits based on prompt size, output complexity, and the model tier you choose (Mini / Pro / Max). There is a free tier with a limited monthly credit allowance and a daily message cap — enough to sample it. Confirm current plans and token rates on v0.dev.2026 年 2 月起，v0 改为按 token 计费：每个套餐含月度额度，每次生成按提示词长度、输出复杂度与所选模型档位（Mini / Pro / Max）扣额度。有免费档可试用（月度额度有限、每日消息数有上限）。最新套餐与 token 费率以 v0.dev 官网为准。
v0 is the UI specialist of the AI builder world, and it shows in the output: the interface quality is genuinely a cut above generic prompt-to-app tools. The honest trade is specialization — it is brilliant inside the React/Next/Vercel stack and a UI engine rather than a full-stack builder. If your bottleneck is frontend quality (landing pages, dashboards, marketing sites), v0 is the fastest path from idea to something you'd show a customer; pair it with a backend service for the rest. And budget for two bills: v0 credits plus Vercel hosting.
v0 是 AI 构建工具里的"界面专科医生"，输出质量确实比通用提示词转应用工具高一档。代价是专精：它在 React/Next/Vercel 技术栈里如鱼得水，但本质是 UI 引擎而非全栈构建器。如果你的瓶颈是前端质量（落地页、仪表盘、营销站），v0 是从想法到"敢给客户看"的最快路径；后端部分另配服务。预算上要算两笔账：v0 的额度 + Vercel 的托管费。

Who Should Use v0?谁适合使用v0？
✓ Good Fit For适合以下场景
- Founders and marketers who need a polished landing page this week本周就要上线精美落地页的创业者与市场人
- Frontend developers in the React/Next/Vercel stack who want a head start已在 React/Next/Vercel 技术栈、想快速起手的前端开发者
- Designers turning screenshots or Figma files into working code想把截图或 Figma 稿变成可运行代码的设计师
✕ Not Ideal For不适合以下场景
- Full-stack apps needing built-in auth, databases, and backend logic需要内置登录、数据库与后端逻辑的全栈应用
- Teams outside the React/Next ecosystem (value drops sharply)不在 React/Next 生态的团队（价值大打折扣）
Getting Started with v0v0 快速开始
1. Open v0.dev and sign in — the free tier is enough to sample UI generation打开 v0.dev 并登录——免费档足够体验 UI 生成2. Describe the interface in words, or upload a screenshot / import from Figma用一句话描述界面，或上传截图 / 从 Figma 导入设计稿3. Refine in visual design mode, sync to GitHub, then one-click deploy to Vercel在可视化设计模式里微调，同步到 GitHub，一键部署到 VercelKey Features核心功能
-
Prompt / Screenshot / Figma to UI提示词 / 截图 / Figma 转界面 — Describe the interface in words, upload a screenshot, or import a Figma design — v0 turns it into working React code.一句话描述、上传截图或导入 Figma 设计稿——v0 把它变成可运行的 React 代码。
-
React + Tailwind + shadcn/ui OutputReact + Tailwind + shadcn/ui 代码输出 — Production-grade components following React best practices, with accessibility baked in — code developers will actually ship.遵循 React 最佳实践的生产级组件，默认带无障碍支持——是开发者真的敢上线的代码。
-
Visual Design Mode可视化设计模式 — Nudge spacing, colors, and layout visually instead of going back to prompts for every tweak.直接可视化调整间距、颜色与布局，不用为每次微调重写提示词。
-
One-Click Vercel Deploy + GitHub Sync一键部署 Vercel + GitHub 同步 — Ship the generated UI to Vercel in one click, and sync the code into your GitHub repo for team workflows.一键把生成的界面部署到 Vercel，并同步代码进 GitHub 仓库，适配团队协作流。
-
Token-Based Credits (Since Feb 2026)Token 计费额度（2026-02 起） — Each plan includes monthly credits; usage is metered by model tier (Mini / Pro / Max) and tokens. Unused credits roll over briefly.每个套餐含月度额度，按模型档位（Mini / Pro / Max）与 token 计量；未用完的额度可短暂结转。
Pros & Cons优缺点
✓ Good Fit For适合以下场景
- Best-in-class AI UI and component generation qualityAI 界面与组件生成的质量同类最佳

- Figma import and visual editing fit real design-to-code workflowsFigma 导入与可视化编辑贴合真实的设计转代码流程
- Seamless deploy + GitHub sync inside the Vercel ecosystemVercel 生态内无缝部署与 GitHub 同步
✕ Not Ideal For不适合以下场景
- Frontend-first — no built-in auth, databases, or backend logic纯前端导向——无内置登录、数据库与后端逻辑
- Stack lock-in: built around React / Next.js / Vercel技术栈锁定：围绕 React / Next.js / Vercel 构建
- Token burn is hard to predict; complex generations cost far moreToken 消耗难预估，复杂生成的花费高得多
- Vercel hosting is billed separately from v0 creditsVercel 托管费与 v0 额度分开计费
