Vibe Coding: Build Ai Apps With Openai, Supabase & N8N

Learn to build real AI-powered apps with OpenAI, Supabase, n8n, VibeCoding, Stripe, and modern automation tools

What you'll learn

Build and deploy full-stack AI apps using OpenAI, Supabase, and n8n

Design automation workflows that integrate AI agents and real-time data

Store and query embeddings in Supabase vector store for RAG use cases

Create authentication, user limits, and Stripe payments in real projects

Requirements

A basic understanding of how APIs work is helpful but not required

Familiarity with JavaScript or any programming language is a plus, but not required

No prior AI, OpenAI, or n8n experience needed — everything is explained step-by-step

A willingness to learn by building real-world, hands-on projects

Description

Unlock the full power of AI by building real, production-ready applications — no fluff, no theory-only lessons.In this hands-on course, you'll learn how to create full-stack AI-powered apps using the Vibe Coding workflow. You'll connect tools like OpenAI, Supabase, n8n, and Stripe to build apps that go beyond basic demos — from data workflows and embeddings to user auth, chat interfaces, and payments.You’ll start by learning how to build AI workflows using OpenAI and n8n, then integrate Supabase to handle vector storage, chat memory, and user authentication. You’ll even learn how to query metadata, test webhooks, and build out a full front-end experience — including login/signup forms, transcript-driven UIs, and real-time chat. We’ll top it all off by integrating Stripe for a working free/pro plan flow and show you how to fully deploy your app to production.Whether you're a developer, automation enthusiast, or entrepreneur looking to build your own AI tools — this course gives you the real skills and system design patterns to do it confidently.By the end, you’ll not just understand AI workflows — you’ll have built and deployed a full-stack AI app from scratch.And if you don’t find the course valuable, no worries — you’re covered by Udemy’s 30-day money-back guarantee. Enroll risk-free and start building!
