In this video, I demonstrate how you can create sophisticated, client-branded applications entirely without writing code by leveraging Lovable for the front‑end, Supabase for the backend and database, and n8n for automation and complex logic. I walk through a practical example: building a multi‑step article generation application. First, I discuss crucial early decisions like choosing between a multi‑instance vs. multi‑tenant architecture and options for handling client payments. The building process starts with designing the user interface using UXPilot.ai based on natural language prompts. Then, I take these designs and use Lovable to build the dynamic front‑end application, including setting up user authentication managed via Supabase. Next, I connect Supabase as the backend, setting up a new project to handle the database, user authentication, and secure storage of API keys and webhook URLs using Supabase secrets. The core functionality is powered by several distinct n8n automation scenarios, each triggered by a secure webhook call from the Lovable app. I show how to create, test, and integrate workflows for generating an article outline (using Perplexity and Anthropic Claude), generating the full article content (using Anthropic Claude, responding in HTML), generating a featured image (using fal.ai), and publishing the final article to WordPress. Throughout the integration process, I demonstrate prompting Lovable to make these webhook calls, pass data, handle responses, and populate the UI. I also cover troubleshooting common issues, iterating on Lovable's code to fix errors or refine the UI (like the rich text editor), and adding security layers like authorization headers. I perform an end‑to‑end test and verify data persistence in the Supabase database. Finally, I explain the benefits of breaking down the backend logic into separate n8n “microservices”, show how to publish the finished app using Lovable's deployment features, add new client users via Supabase, and extend functionality (like adding an image regeneration feature). By the end of this tutorial, you'll understand how to connect Lovable, Supabase, and n8n to build and deploy functional, client‑ready web applications without needing traditional coding skills.
