The vibe coding landscape has exploded. Lovable and Dev (formerly v0.dev) represent two approaches to AI-powered application building — and neither is what most engineering teams actually need.
What They Do
Lovable generates full-stack applications from natural language descriptions. You describe what you want, it builds a React + Supabase app. Good for prototyping. Questionable for production.
Dev (Vercel) takes a more focused approach — generating UI components from descriptions and screenshots. Tighter scope, higher quality output within that scope.
Both are tools for applications. Neither helps you existing ones.
