Bolt.new vs v0
These two get lumped together but they do different jobs. Bolt.new builds full-stack apps you can run, iterate, and deploy in the browser. v0 generates UI and components with strong design taste, native shadcn/ui output, and the Vercel ecosystem behind it.
Bolt wins for full apps with backend logic. v0 wins for polished UI and component generation in a Next.js + shadcn/ui world.
The tools at a glance
Bolt.new
by StackBlitz
In-browser AI builder with a real WebContainer dev environment and broad framework support.
- Best for
- Full-stack prototyping with iteration and deploy in one place.
- Standout
- Live WebContainer IDE means the AI is editing a real running project, not generating dead code.
- Weakness
- Design output is generic compared to v0 — fine, not stunning, by default.
- Pricing
- Free tier (limited tokens); Pro $20/mo; Teams $30/seat
v0
by Vercel
AI UI generator focused on shadcn/ui components and Next.js, with strong design defaults.
- Best for
- Generating production-quality React components and screens.
- Standout
- Design taste — output looks like a real designer touched it, with shadcn/ui and Tailwind dialed in.
- Weakness
- Not a full-stack app builder — backend, data, and auth are not its job.
- Pricing
- Free tier; Premium $20/mo; Team $30/seat
Key differences
Backend support
Bolt scaffolds API routes, server logic, and DB calls inside its WebContainer. v0 generates frontend components; backend is on you. If your prompt is "build me an app that does X with users", Bolt is the right shape.
Frontend stack
v0 is built for Next.js + Tailwind + shadcn/ui and excels there. Bolt supports Astro, Remix, SvelteKit, Vite, and Next.js. For Next + shadcn projects v0 produces noticeably nicer UI; for everything else, Bolt is the only choice.
Design quality
v0 wins clearly. Components have considered spacing, typography, and dark mode. Bolt UI is functional but unopinionated — it is the kind of UI you would get from any decent code-gen tool.
Iteration speed
v0 iterates on a single component or screen in seconds and you copy the code out. Bolt iterates on an entire running app, which is more powerful but slower per turn. For UI exploration, v0's loop is shorter.
Deployment
Bolt has one-click deploy from its in-browser environment. v0 outputs code you typically push to a Vercel project — same ecosystem, just one extra step. Both deploy fine; Bolt's is more in-tool, v0's is more idiomatic for Next.js teams.
Pricing
Both Pro tiers are $20/mo. v0 charges in messages/credits scaled to model usage; Bolt in tokens. Real-world cost is similar for similar-sized projects, but v0 stretches further on UI-only work because each generation is smaller.

Pick by use case
Generating polished UI components
v0's shadcn/ui defaults and design taste produce components a designer would actually ship.
App with complex backend logic
Bolt scaffolds API routes, runs them live, and lets you iterate on server code. v0 is not built for this.
Designer prototyping production-quality UI
Single-component iteration plus design polish makes v0 the closest thing to Figma-with-code today.
Quick landing page demo
Faster to a beautiful single page. Bolt works but the output looks more generic.
Hackathon / weekend project (full app)
You need a working app with data flow by Sunday. Bolt iterates on the whole thing in one tool.
Adding components to an existing Next.js app
Generate, copy, paste into your repo. v0 fits the existing-codebase workflow better than Bolt.
Production-bound real product
For a full app you intend to ship, Bolt covers more of the stack. Pair with v0 for the UI polish if needed.
