I Built a Full-Stack App Without Writing a Single Line of Code
In this video, I'll show you step-by-step how to build and deploy a full-stack application using AI — completely without writing a single line of code. We'll go from a blank folder to a fully deployed, live application using Google's Antigravity, Claude Code, and Firebase.
You'll learn:
How to set up Google Antigravity and connect Claude Code
How to create a Claude.md framework file to control how the AI builds your app
How to use plan mode to instruct Claude Code on what to build
How to provide design inspiration from Dribbble to control the look and feel
How to test, debug, and iterate on your application with screenshots
How to add authentication (login with Google and email) using Firebase
How to install and use Firebase MCP servers with Claude Code
How to deploy your finished application live using Firebase hosting
By the end, you'll have a fully functional, deployed full-stack application with authentication — built entirely with AI and zero coding experience.
