Today we're launching as Lovable (previously gptengineer.app) since it's such a big change.\n\nThe problem? AI writing code typically make small mistakes and then get stuck. Those who tried know the frustration. We fixed most of this by mapping out where LLMs fail in full-stack dev and engineering around those pitfalls with prompt chains.\n\nThanks to this, in all comparisons I found with: v0,",{"problem":43,"audience":49,"pricing":50,"motivation":49,"time_to_build":49,"stack":54,"openness":63,"stage":64,"team_size":65},{"value":44,"source":45,"evidence":46},"LLM-written code makes small mistakes and gets stuck when building full-stack apps","maker",[47],{"id":48},"post",null,{"value":51,"source":45,"evidence":52},"Free tier available for now",[53],{"id":48},[55,59],{"value":56,"source":45,"evidence":57},"Supabase integration",[58],{"id":48},{"value":60,"source":45,"evidence":61},"microVMs for dev environments",[62],{"id":48},"unknown","launched","team",{"praise":67,"objections":83,"requests":91,"questions":92,"alternatives":105},[68,76],{"value":69,"source":70,"evidence":71},"Generates working full-stack web apps from prompts","commenter",[72],{"id":73,"by":74,"text":75},"42207101","GameBuddyCedric","Already love what it can already do!
