v0 Limitations: What It Can't Do
v0 by Vercel is ai-powered ui component generator that creates react/next.js components from prompts and images. While it excels at ui component generation, design-to-code, shadcn/ui projects, it has significant limitations for full applications, backend logic, database-driven apps. The main issues are: ui only - no backend, components need integration work, limited application architecture.
Key Takeaway: v0 gets you about 70% of the way to a working app. The last 30% typically requires professional development to achieve production quality.
Main Limitations of v0
UI Only - No Backend
v0 only generates frontend components. There's no database, API, or backend logic. You need to build or integrate everything else yourself.
Components Need Integration Work
Generated components are standalone. Connecting them to state management, APIs, and routing requires developer knowledge.
Limited Application Architecture
v0 generates individual components, not complete applications. You still need to architect how everything fits together.
Iteration Limits on Free Tier
The free tier has strict generation limits. Complex UIs requiring multiple iterations quickly exhaust free credits.
When v0 Works Well
v0 is best for: UI component generation, design-to-code, shadcn/ui projects
- Excellent UI component generation
- High-quality Tailwind code
- shadcn/ui integration
- Copy-paste ready components
When to Avoid v0
v0 is NOT suitable for: Full applications, backend logic, database-driven apps
- Components don't connect to anything
- No way to add backend logic
- Styling conflicts with existing code
- Need developer to integrate

Can v0 build a complete app?
No. v0 only generates UI components. For a complete app, you need to add backend logic, database connections, authentication, and state management separately or use v0 alongside other tools.
Is v0 better than Lovable or Bolt?
Different tools for different purposes. v0 excels at generating high-quality UI components but has no backend. Lovable and Bolt attempt full applications but with lower UI quality. Many developers use v0 for UI and other tools for logic.
How do I use v0 components in my project?
v0 generates copy-paste ready code. Copy the component, add it to your project, then connect it to your state management and backend. This requires React development knowledge.
