v0 vs Bolt.new
v0 generates beautiful, reusable UI components. Bolt.new builds full working prototypes. They're complementary — use v0 for design, Bolt for demos.
v0 and Bolt.new are both popular choices for vibe coding frontends, but they solve different problems. v0 generates polished, reusable React components using shadcn/ui and Tailwind. Bolt.new generates entire working applications in a browser WebContainer. v0 gives you beautiful building blocks; Bolt gives you a running prototype. Understanding what each actually produces — and what's missing — is critical before you invest in either approach.
Head-to-head comparison
Code Quality
v0v0
Excellent component-level code. Clean React with proper TypeScript, shadcn/ui, and Tailwind. Well-structured, accessible, and following best practices. Individual components are production-grade.
Bolt.new
Working app-level code that varies in quality. File organization is minimal, TypeScript is loose, and logic tends to live in a few large files. Gets the job done but needs refactoring.
Security
v0v0
Components are pure UI — no security surface. Security only becomes relevant when you wire them to a backend, and that's entirely your responsibility.
Bolt.new
No security layer. No auth, no input validation, API keys sometimes hardcoded in source. The prototype works but has zero protection.
Ease of Use
Bolt.newv0
Prompt-driven but aimed at developers. You get component code you need to integrate into a project. Requires React and Next.js knowledge.
Bolt.new
Prompt-driven and aimed at everyone. You get a running app in the browser instantly. No coding knowledge required to get started.
Deployment
Bolt.newv0
No deployment — v0 outputs components, not apps. You integrate the code into your own project and deploy that project yourself.
Bolt.new
Export from the WebContainer and deploy to Vercel, Netlify, or any host. May need env var configuration and cleanup, but the process works.
Scalability
Tiev0
Components are inherently scalable — they're stateless UI pieces. But you need to build the entire application architecture around them yourself.
Bolt.new
Prototypes are not built for scale. No data layer, no caching, no optimization. Scaling means rebuilding the architecture, not just adding servers.
Design Polish
v0v0
Best-in-class visual output. Consistent design system, proper spacing, responsive layouts, and accessibility baked in. The gold standard for AI-generated UI.
Bolt.new
Good-looking demos but less consistent. Design quality depends heavily on the prompt. Can produce impressive visuals but cohesion varies across pages.
Code quality
v0 produces higher-quality code at the component level — cleaner, more accessible, and more reusable. Bolt produces more complete applications but at lower code quality. If you need beautiful UI building blocks, v0 is unmatched. If you need a working prototype fast, Bolt delivers. The ideal workflow for many founders is to use v0 for design direction and Bolt (or another full-stack tool) for the actual app.
Security
v0 has no security concerns because it's pure UI. Bolt has no security infrastructure because it's a prototyping tool. The real security work begins when you build a backend behind v0 components or harden a Bolt prototype for production. In both cases, security is something you add — neither tool provides it.
Which should you choose?
Choose v0 if...
Developers who need polished, accessible UI components for an existing project. Best for design-heavy applications where visual quality matters.
v0 servicesChoose Bolt.new if...
Anyone who needs a working prototype quickly. Best for demos, stakeholder presentations, and validating ideas before investing in production development.
Bolt.new servicesThe bottom line
v0 for components, Bolt for prototypes. They're complementary rather than competitive. Use v0 when you need beautiful UI that will last. Use Bolt when you need a working demo by tomorrow. If you've vibe coded an app in Bolt and want to take it to production, expect to rebuild the backend, add security, and potentially replace the UI with cleaner v0 components. SpringCode reviews code from both tools and can map the exact work needed to go live.

Frequently asked questions
Can I use v0 components inside a Bolt project?
After exporting from Bolt, yes. Both use React, so v0 components can replace Bolt's generated UI. Install shadcn/ui in the Bolt project, swap components, and you get Bolt's app structure with v0's design quality. This requires development experience.
Which is better for a non-technical founder?
Bolt. It gives you a running app you can click through and show to investors. v0 gives you code that needs a developer to integrate. If you're non-technical, start with Bolt for your prototype and bring in a developer when you're ready for production.
