Build a SaaS App in 18 Mins with Lovable! (Vibe Coding Tutorial)
Helena Liu • July 12, 2025
Helena Liu demonstrates how to use the vibe coding platform Lovable to rapidly build and publish a web-based AI SaaS app—in this case, an AI-powered shore-excursion assistant called Shirley—by leveraging ChatGPT prompts. She covers idea generation, natural-language iteration, Supabase backend integration, version history, and custom domain deployment to launch an MVP in under an hour.
Key Takeaways:
- Helena developed an app concept from her Mediterranean cruise experience—an AI companion that generates custom walking or taxi itineraries and recognizes landmarks via image uploads to save users hundreds on shore excursions.
- By pasting a detailed ChatGPT-generated prompt into Lovable, she spun up a fully functional prototype with UI elements, photo upload, and itinerary tab within minutes, then linked it to Supabase for user authentication and database storage.
- Lovable enables iterative development through natural-language fixes (e.g., resolving build errors, adding login/logout, removing fields), offers code view and version history, and supports publishing with custom domains for rapid MVP launches.
