Summary:
In this video, I build a fully functional SaaS-style web app from scratch using vibe coding—no traditional coding required. I walk through creating a production-ready tool with real integrations like LLMs for text, Nano Banana Pro for image generation, and Stripe for payments, all wrapped in a polished, modern UI. You’ll see how Emergent’s agentic vibe coding system plans, builds, tests, and debugs the app through simple prompts, plus best practices for writing effective prompts, iterating on features, and fixing issues efficiently. This serves both as a full build demo and a practical vibe coding tutorial you can apply to your own projects.
