Bolt.new vs Lovable vs v0 vs Cursor
Which Builds Better Apps?

What We Look For

We have fixed apps from all four tools. Our comparison is based on real-world experience with production deployment, not benchmarks or marketing claims. We look at: how often apps need fixing, what types of issues are common, and how hard they are to debug.

Lovable — Best for UI-Heavy Apps

Strengths: Excellent UI quality, good component library, smooth design system integration. The output looks polished and professional.

Common issues: Backend is often the weakest part. API routes and database integrations tend to need the most work before production.

Verdict: Great for UI-heavy apps where the frontend is the product. Expect to spend extra time on the backend.

Bolt.new — Best for Full-Stack Speed

Strengths: Fast iteration, good for MVPs, strong on both frontend and backend. The most balanced of the four tools.

Common issues: Code quality varies widely between iterations. The more you use it, the more inconsistencies accumulate. State management can get messy.

Verdict: Best for speed-to-MVP. Plan a refactoring session after the initial prototype is done.

v0 — Best for React Components

Strengths: Exceptional React component quality, clean TypeScript, excellent for UI components and pages. The code is often the cleanest of the four.

Common issues: v0 generates components, not full apps. You need to assemble the pieces yourself. Integration between components is often where things break.

Verdict: Best for generating individual components or pages. Requires more assembly work than the other tools.

Cursor — Best for Technical Teams

Strengths: Most powerful for developers who understand code. The AI can refactor, explain, and extend existing codebases. Best for iterating on a project you already understand.

Common issues: Requires technical expertise to use effectively. The code quality depends entirely on the prompts and context provided. Lower-quality prompts produce lower-quality code.

Verdict: Best for developers. Not recommended for non-technical founders without developer support.

The Honest Truth

All four tools produce prototypes that need work before production. The differences are in what kind of work is needed. Our recommendation: choose based on your technical level and the type of app you are building, then budget for a production hardening phase.

We fix apps from all four tools. The production-readiness timeline is similar across all of them — plan for 1-3 days of hardening after the prototype phase.
