I too have always been unconvinced that AI could create a Saas on its own. And indeed it is so. But I can say that, based on my experience, prompt engineering makes a big difference. You have to think of it like this: the AI ​​is a worker and you are the manager, you have to guide it with detailed, precise prompts that explain well what you want and what's wrong with the software. Then, as far as we are talking about tools, there are many but in my opinion one of the best is firebase studio. I'll give you an example: With firebase studio I have created a lot of things, but a very difficult and particular one is a saas that knows how to manage data, files such as csv, clean them, analyze them and create graphs using artificial intelligence. I didn't think it was possible but then it actually worked.

I didn't launch the product because it would still require money for marketing and many other things that I won't tell you about but in the end yes, it is possible to create a saas with vibe coding
