I have used a few products to vibe-code my applications. The first one I used was Chatgpt. From this, I created my first application and it had a very average UI. I was using nextjs for frontend and backend, so for me, the backend part took time but it was decent. The second product which is good enough for me currently is Gemini. This creates a very good UI and backend at the same time. The first time I used it, it was a super upgrade in the UI. I also used Lovable to create one practice project, but I don't know why I did not used again.
I also heard people's suggestion of using different AI's like claude, cursor etc. but moving in to a different platform has some friction. What AI is most used or easiest to build an application? I recently heard of a new AI called Emergent, which creates the whole application with a single prompt.
