Lovable (formerly GPT Engineer) turns plain-English descriptions into deployable full-stack applications. Features visual drag-and-drop editing, Supabase database integration, GitHub sync, and one-click deployment to Vercel or Netlify. The fastest path from idea to working web app — no local dev environment required. Best suited for MVPs, prototypes, and client demos. Panel verdict: 2/3 Ship — impressive for rapid prototyping, but code quality degrades on complex apps.
Reviewer scorecard
“Still the most used JS testing framework. Massive ecosystem of matchers, plugins, and documentation.”
“Best MVP builder on the market right now. The Supabase integration means you get a real database, not just a frontend. GitHub sync seals the deal.”
“Vitest does everything Jest does faster with better ESM support. New projects should start with Vitest.”
“The demos are impressive but dig deeper and you'll find spaghetti code, missing error handling, and no tests. Fine for demos, dangerous for production.”
“Jest defined modern JS testing but Vitest is the future. The migration is happening steadily.”
“I built a client project prototype in under an hour. They were blown away. Even if I rewrite the code later, the speed-to-wow is worth the subscription alone.”
