What Is This Comparison?这篇对比讲什么？
Vibe coding means describing an app in plain language and getting working software back — but the three leaders do not do the same job. Lovable (formerly GPT Engineer) is a full-stack builder: prompt in, get frontend plus backend, authentication and database (via Lovable Cloud / Supabase), then one-click deploy. v0 by Vercel is a frontend specialist: it turns text, screenshots or Figma designs into production-quality React components with shadcn/ui and Tailwind CSS — and stops there, with no built-in backend. Bolt.new by StackBlitz runs a full Node.js environment in your browser via WebContainer: no local setup, live preview, instant deploy, and a clean project download.vibe coding 就是用自然语言描述、拿回能跑的软件——但三强做的不是同一件事。Lovable（前身 GPT Engineer）是全栈 builder：输提示词，拿回前端 + 后端 + 登录 + 数据库（经 Lovable Cloud / Supabase），一键部署。Vercel 的 v0 是前端专家：把文字、截图或 Figma 设计变成高质量 React 组件（shadcn/ui + Tailwind CSS）——也只做到这一步，不带后端。StackBlitz 的 Bolt.new 用 WebContainer 在浏览器里跑完整 Node.js 环境：零本地配置、实时预览、即时部署、项目可干净下载。
Pricing is where the three diverge most in practice. All three have a free tier that is best understood as a trial: third-party 2026 roundups put Lovable free at about 5 messages a day, Bolt.new free at roughly 300K tokens a day (1M a month), and v0 free at a small monthly credit/message allowance — but the roundups disagree on v0's exact free allowance (older ones say about $5 credits a month, newer ones say 7 messages a day), so treat every free-tier figure here as approximate. Paid entry sits around $20–25 a month for all three (Lovable Pro $25, Bolt.new Pro $25, v0 paid from about $20–30 depending on the roundup and plan). Confirm the live rate card on each vendor's official site before budgeting. All three single-tool pages already exist on this site — see Lovable, v0 and Bolt.new.三家分歧最大的其实是价格形态。三家都有免费档，但都只能理解为试用：2026 年第三方横评把 Lovable 免费档记为约每天 5 条消息，Bolt.new 免费档约每天 30 万 token（每月 100 万），v0 免费档为少量月度 credits/消息额度——但各家横评对 v0 免费额度的说法不一（旧的说每月约 $5 credits，新的说每天 7 条消息），所以本页所有免费额度数字都只是约数。付费起步三家都在每月 $20–25 左右（Lovable Pro $25、Bolt.new Pro $25、v0 付费约 $20–30，视横评与档位而定）。做预算前请到各家官网核对实时价目。三家的单品页本站都已上线——见 Lovable、v0 与 Bolt.new。
The honest verdict: Lovable wins if you cannot code and need accounts, payments and a database in one place; v0 wins if you can code and the interface is the deliverable; Bolt.new wins if speed and a clean download matter more than a managed backend. None of them ships production software without technical review — budget for cleanup, auth hardening and real hosting whatever you pick.
实在的结论：不会写代码、又要账号/支付/数据库一步到位，选 Lovable；会写代码、界面本身就是交付物，选 v0；要速度、要一份干净可下载的项目，选 Bolt.new。三家都不会在没有技术复核的情况下直接产出可上线的软件——无论选谁，都要为清理代码、加固登录与真实托管留预算。

Who Should Use It?谁适合用？
✓ Good Fit For适合以下场景
- Non-technical founders shipping an MVP with accounts and data不会写代码、要带账号与数据的 MVP 的创业者
- React developers who want the best UI output per prompt想一句话拿到最好 UI 的 React 开发者
- Anyone who wants a working prototype today, with zero setup今天就要跑起原型、不想装环境的任何人
✕ Not Ideal For不适合以下场景
- Complex production systems with custom architecture架构定制复杂的生产系统
- Teams that need a managed backend plus pixel-perfect UI in one tool既要托管后端、又要像素级 UI、还想一个工具全包的团队
- Anyone expecting zero cleanup after generation指望生成完零清理的人
Getting Started快速开始
1. Write one real brief (audience + core action + data it stores) and run it in all three1. 写一份真实需求（用户 + 核心动作 + 存什么数据），三家各跑一遍2. Compare the same three things: does it run, can you log in, can you export it2. 对比同一三项：能不能跑、能不能登录、能不能导出3. Pick by the bottleneck you hit first — backend, UI quality, or speed3. 按你先撞到的瓶颈选：后端、界面质量，还是速度Key Features核心功能
- Lovable: Full-Stack in One PromptLovable：一句话全栈 — Frontend, backend, auth and database from one prompt, with Lovable Cloud / Supabase underneath and one-click deploy.一句话出前端、后端、登录与数据库，底层是 Lovable Cloud / Supabase，一键部署。
- v0: React UI at Production Qualityv0：生产级 React 界面 — Text, screenshot or Figma input becomes React + shadcn/ui + Tailwind components; image-to-code and Figma import are its signature strengths.文字、截图或 Figma 输入变成 React + shadcn/ui + Tailwind 组件；图转码与 Figma 导入是招牌。
- Bolt.new: Zero-Setup Browser IDEBolt.new：零配置浏览器 IDE — A full Node.js environment via WebContainer in the browser — no install, live preview, instant deploy, clean project download.浏览器里经 WebContainer 跑完整 Node.js 环境——不用安装、实时预览、即时部署、项目可干净下载。
- Export Paths Differ — Check First导出路径各不相同——先验 — Lovable syncs via GitHub, v0 exports components/builds, Bolt.new downloads the whole project. Your files are your insurance.Lovable 经 GitHub 同步、v0 导出组件/构建产物、Bolt.new 下载整个项目。文件在手才是保险。
- Credit / Token / Message Metering三种计费方式 — Lovable meters credits, Bolt.new meters tokens, v0 meters messages/credits — so the same project can cost very different amounts on each. Prices per official site.Lovable 按 credits、Bolt.new 按 token、v0 按消息/credits 计费——同一个项目在三家花的钱可能差很多。价格以官网为准。

- v0 has no built-in backend, auth or databasev0 没有内置后端、登录与数据库
- Bolt.new token burn climbs fast on complex apps; long sessions can lose contextBolt.new 在复杂应用上 token 烧得快；长会话可能丢上下文
- Lovable gives you less control over architecture detailsLovable 对架构细节的控制较少
