Most comparison articles about AI app builders come from people who tried each tool once. We ship products with them daily.
At , our most complex product (voice-to-structured-data workspace with real-time collaboration), entirely in Lovable. The Supabase integration handles auth, database, real-time subscriptions, and file storage without leaving the platform.
Where it hurts: When the AI hallucinates a wrong import or generates broken SQL, debugging happens inside a chat interface, not a proper IDE. For complex state management or edge function logic, we sometimes copy the code to Cursor, fix it there, and push back through GitHub.
Pricing reality: Free tier gives you 5 credits per day. The Pro plan ($25/month) gives 100 credits, which runs out fast during active development. Plan for 2-3 months of Pro if you are building something real.
Bolt: fastest for throwaway prototypes
Bolt runs entirely in the browser through WebContainers, so there is zero local setup. When we need to test an idea in 15 minutes, Bolt is the first pick.
It supports more frameworks than any competitor: React, Vue, Svelte, Angular, Astro, Remix, Next.js, Expo. If your team is not on React, Bolt is likely the only option.
The tradeoff is architectural control. Bolt generates code that works for the demo but does not structure it for long-term maintenance. There is no built-in database integration, so you are wiring Supabase or Firebase yourself. Deployment options are limited compared to Lovable's one-click custom domain setup.
We used Bolt early on for rapid concept validation. Once a concept proved viable, we rebuilt in Lovable for production. That two-step workflow ("prototype in Bolt, ship in Lovable") saved us from investing credits on ideas that did not survive first contact with users.
v0: component-level precision
Vercel's v0 is not an app builder. It is a component generator, and a very good one. It produces polished React and Tailwind components from a description. The output quality is consistently higher than what Lovable or Bolt generate for individual UI pieces.
We reach for v0 when we need a specific UI component (a pricing table, a dashboard card, a multi-step form) and want it to look excellent out of the box. Then we drop the generated code into our Lovable project.
The limitation is scope. v0 does not generate backends, databases, or authentication. It does not deploy anything. If you want a full product, v0 is one tool in the chain, not the chain itself.
Cursor: when you need a real IDE
Cursor is a VS Code fork with AI deeply integrated. Unlike the tools above, it assumes you know how to code. The AI assists rather than generates.
We use Cursor for the parts that chat-based builders handle poorly: debugging complex business logic, refactoring Supabase edge functions, reviewing generated code for security issues. Our to catch the issues that slip through AI-generated code. If you are shipping vibecoded products to real users, auditing the output is not optional.
No single tool covers everything. The right question is not "which is best" but "which do I reach for at this stage."
