If yes, can you please share the scenario where you use them. Is it only for mockups or you are actually running a product using these?
I've seen both.
The interesting distinction isn't whether people can launch with tools like Lovable or Replit—it's where they stop being the right abstraction. For many founders they're great for validating an idea quickly, but the real question is whether your product's long-term advantage depends on the code itself or on the business you're building around it.
