Pixie gets my vote too. Naming it after your cat makes it memorable, and it feels a lot friendlier for a tool people trust with their code. Nice rebrand.
I built a website using Lovable to solve a real problem I kept running into as a freelance web developer my client needing a fast, professional site without the usual back-and-forth of traditional development. I used AI-assisted building to go from idea to a working, responsive site quickly, focusing on clean design and usability. This project shows how Lovable lets someone like me deliver real results for clients faster, without sacrificing quality.
Hey! Quick heads-up: your Lovable project link currently shows a "You don't have access / This project is private" screen.
You might want to toggle the project visibility to Public in Lovable settings or share the published .lovable.app URL so judges and the community can view it properly.
