Lovable is the closest thing to a "full-stack AI developer" you can hire for $20/month. It handles auth, database, backend logic, and frontend in one coherent system. The Supabase integration is seamless — you describe what you want, and it sets up the tables, RLS policies, and API calls automatically.
Where Lovable shines: building real products that need to persist data, handle users, and eventually charge money. If you're building a SaaS, Lovable is the default choice.
You're building a real SaaS product with users, data, and payments. Anything that needs a backend. Subscription apps, marketplaces, booking systems, internal tools.
Bolt (by StackBlitz) is the fastest tool for going from idea to working prototype. The in-browser development environment means zero setup — you're coding in seconds. For quick demos, hackathon projects, or testing an idea, nothing beats Bolt's speed.
The tradeoff: Bolt is less opinionated about architecture, which means you get more flexibility but also more responsibility. It won't automatically set up your database or auth — you'll need to wire those up yourself.
You need a working prototype fast. Hackathons, demos, MVPs where you'll handle the backend separately. Also great for frontend-only projects like landing pages and tools.
v0 by Vercel is the best tool for generating beautiful, production-ready UI components. If you need a pricing table, a dashboard layout, or a complex form — v0 will produce the cleanest code. It uses shadcn/ui and Tailwind by default, which means the output integrates perfectly with modern Next.js projects.
The limitation: v0 is a UI tool, not a full-stack tool. It doesn't handle backend logic, databases, or auth. Think of it as a very smart UI designer that writes code.
You need beautiful UI components for an existing project. Landing pages, marketing sites, component libraries. Also great as a "design system generator" for your Next.js app.
Cursor is different from the others — it's an AI-powered IDE, not a no-code builder. You write code alongside the AI, which means you need some coding knowledge. But for complex projects that outgrow the other tools, Cursor is unmatched.
The real power of Cursor is in its context awareness. It understands your entire codebase, can refactor across multiple files, and handles complex architectural decisions. If you're building something serious, Cursor is where you'll end up.
Your project has grown beyond what Lovable/Bolt can handle. When you need precise control, complex business logic, or you're working on an existing codebase.
Building a SaaS? Start with Lovable. It handles the full stack and gets you to a working product fastest.
Need a quick prototype? Use Bolt. Zero setup, fast iteration, great for demos.
Building UI components? Use v0. The output quality is unmatched for React/Next.js projects.
Working on a complex codebase? Use Cursor. It's the only tool that scales with your project's complexity.
The good news: these tools complement each other. Many builders use v0 for UI, Lovable for the backend, and Cursor for complex features. Pick the right tool for the job.
