How To Build & Deploy Full Stack Apps for FREE With Antigravity (No Code)

Walkthrough of building and deploying a full-stack habit-tracker using Anti-Gravity (no-code AI dev tool). The host demonstrates project setup, three-layer framework, UI design, testing, Firebase authentication integration via MCP, and final hosting, with live examples and practical tips.

• Project setup & tools: Connect Google account, create project folders, use the explorer/chat UI, and choose models (Gemini 3 Pro vs Claude Opus 4.5).
• Framework & architecture: Implement a three-layer architecture (directives, orchestration, execution) using a claude.md template to standardize builds.
• Design & planning: Provide UI references (Dribbble), generate a task list and implementation plan, then iterate on styling and functionality.
• Integration, testing & deployment: Install MCP services, connect Firebase for authentication, debug auth flows, and deploy the app to Firebase Hosting.

Quotes:

Build full production-ready applications with authentication and databases without writing a single line of code.

We give it a framework — a step-by-step process — so it doesn’t build things a different way each time.

The better instructions you give it, the better structure, the better prompts, the better frameworks you use, then the better the app will be.
