When to choose each
Replit — UnfragileRank 88/100
Strongest for non-technical founders and product managers building MVPs, students and beginners learning full-stack development without DevOps overhead, rapid prototypers and freelancers who need idea-to-deployed-URL in <30 minutes. Watch out for: Agent occasionally generates incorrect code or misinterprets requirements (error rates unknown).
v0 — UnfragileRank 87/100
Strongest for frontend developers accelerating component scaffolding, designers converting mockups to production React without learning JSX syntax, product managers prototyping features for stakeholder feedback. Watch out for: React/Next.js framework lock-in — no Vue, Svelte, Angular, or non-JS framework support.
Cursor — UnfragileRank 84/100
Strongest for Individual developers writing code daily in familiar frameworks, Teams working with consistent coding patterns and conventions, Developers comfortable with AI-assisted development workflows. Watch out for: Context mechanism is undocumented — unclear how large files or complex codebases affect suggestion quality.

Frequently Asked Questions
Can AI really build a full app from a prompt?
Yes. Tools like Bolt, Lovable, and Replit Agent can generate working web applications from natural language descriptions. They handle frontend, backend, and deployment. Complex apps still need developer refinement.
