v0 vs Bolt.new vs Lovable
Three AI app builders — UI prompts, full-stack browser sandbox, and full-stack with deploy.
v0, Bolt.new, and Lovable are the three most popular AI app builders that try to take you from a prompt to a working web app — no manual setup, no boilerplate. They overlap in the user's mind but differ sharply on what they're optimized for. v0 (by Vercel) is the most polished generative-UI tool — paste a screenshot or describe a component, get production-quality React/Tailwind code that ships to your existing Next.js project. Bolt.new (by StackBlitz) is the full-stack browser sandbox — backend, frontend, database, all running in WebContainer with live preview. Lovable is the closest to 'build me an app and let me deploy it' — full-stack generation with built-in Supabase, GitHub sync, and one-click hosting. Pricing is similar at $20–$25/mo for the entry paid tier, all three have free tiers with limits, and all three use frontier models (Claude, GPT, Gemini) under the hood. The choice is really: do you want UI components for your existing app (v0), a full sandbox to prototype something new (Bolt.new), or a finished deployable app you can iterate on (Lovable)?
Quick verdict — which one for which task
Feature comparison
| Feature | v0 | Bolt.new | Lovable |
|---|---|---|---|
| Pricing | Free tier; Premium $20/mo; Team $30/user/mo | Free tier; Pro $20/mo; Pro 50 $50/mo; Pro 100 $100/mo | Free tier; Pro $25/mo; Teams $30/user/mo |
| Owner | Vercel | StackBlitz | Lovable |
| Output stack | React + Next.js + Tailwind + shadcn/ui (the Vercel canon) | Any — Vite, Next.js, Astro, Remix, even Python; WebContainer-runnable | Vite + React + Tailwind + Supabase (auth, DB, storage) |
| Backend included | Component-focused; backend optional via Next.js routes | Yes — Node.js sandbox runs APIs and DBs in browser | Yes — native Supabase integration (Postgres, auth, storage) |
| Deploy-ready output | One-click deploy to Vercel | One-click deploy to Netlify; or push to GitHub | One-click publish to Lovable subdomain or custom domain |
| Screenshot-to-code | Yes — best-in-class for UI components | Yes — supports image input | Yes — supports image input for layouts |
| Code export / GitHub sync | Copy/paste, npx CLI install, or open in v0 editor | Push to GitHub, download zip | Native GitHub sync — Lovable becomes a co-author of your repo |
| Edit-in-browser |

Pros and cons by tool
Bottom line
v0, Bolt.new, and Lovable are not interchangeable — they're optimized for different points in the product-build spectrum. Many users subscribe to multiple — here's which task each wins: design-to-code components for an existing app go to v0, full-stack prototyping in any framework goes to Bolt.new, deployable end-user apps with auth and DB go to Lovable. Power users keep v0 in the toolkit for component generation regardless of which other tools they use; Lovable is the right pick for non-developers shipping their first MVP; Bolt.new is the right pick for engineers who want a no-install full-stack sandbox. At ~$20–25/mo each, running multiple is a reasonable budget for serious builders — and the tools complement each other in workflow.
Frequently asked questions
Can I move from one to the other if I change my mind?
Sort of. v0 → anything: yes, since v0 outputs standard Next.js code. Bolt.new → anything: yes, push to GitHub and continue. Lovable → anything: yes, it syncs to GitHub, but the Supabase coupling means migrating the backend is significant work. In general, Lovable is the most opinionated and the hardest to leave.
Which one is best for a designer who can't code?
Lovable for end-to-end app building (auth, DB, deploy all handled). v0 if you have a developer to integrate the components into a real app. Bolt.new is closer to 'I'd like to learn what's happening' — it shows you the file tree and code.
Which produces production-quality code?
v0 outputs the cleanest, most standard component code — drops into a real codebase with minimal cleanup. Bolt.new and Lovable produce more app-shaped code that's fine for prototypes and MVPs but typically needs refactoring before serious scale. None of them eliminate the need for a developer reviewing the output before production.
What about Replit, Magic Patterns, Subframe — should I evaluate those too?
Yes if your needs don't match the three above. Replit is a more general code-gen + IDE. Magic Patterns is a UI-component-only competitor to v0. Subframe is design-tool-shaped. The 'right' tool depends on whether you're optimizing for components (v0/Magic Patterns), full-stack prototyping (Bolt.new/Replit), or deployable app shipping (Lovable).
Are these tools secure for serious work?
Generated code can ship the same vulnerabilities you'd write yourself if you weren't careful — exposed API keys, broken auth, no rate-limiting. Lovable's Supabase wiring is the safest default but still needs review. Treat AI-generated apps the way you'd treat any junior-developer code: review before shipping anything that handles user data.
