Can you really build a working web app without writing a single line of code?
In this beginner-friendly walkthrough, I put Lovable.dev to the test and show you exactly how I used vibe coding—a term popularised by Andrej Karpathy—to spin up an interactive Seinfeld trivia app in under two hours.
You’ll see the full workflow, from prompting Lovable’s AI builder to integrating a Supabase database, tweaking UI colours, and fixing game-flow logic… all while staying under the free-tier token limit.
If you’re curious about AI app builders or looking for a fast prototype tool, this demo is for you.
