They’re good enough already. You can one-shot a website with Claude Code or Codex of the same or better quality than Lovable. I have no idea what the appeal of the product is at this point.
may help thinking through what you'd have to do to go from the generated web app to get it running on a website, may be with subscribers, payments, etc. and then operating it. There are so many concepts, constructs, terminology one needs to know to do it without ongoing headaches. Lovable at least takes away some of those pains.
