Google Antigravity and InsForge: build and deploy a SaaS

This tutorial follows a freelancer proposal generator from an AI-generated interface to a deployed SaaS app. The presenter uses Google Antigravity to create a landing page and dashboard from a prompt specifying client details, services, pricing and timelines. An initial SEO example produces a two-page proposal with a PDF download option. At that stage, the presenter explains that the app has no working authentication or persistent storage.

The backend walkthrough uses InsForge. The presenter creates a project, selects a region and runs a supplied CLI command in Antigravity's terminal to connect the project and install skills. A further prompt asks the coding assistant to configure authentication and database tables, then connect them to the interface.

The testing section covers email signup with a verification code, proposal creation, saved history and profile records. The presenter also checks the backend tables and says user data persists after logging out and back in. These are demonstrations and claims about this example, rather than a general security assessment.

Deployment starts with a prompt copied from InsForge's dashboard. The presenter reports receiving a live URL without manually connecting GitHub or Google Cloud, and points to environment variables and custom domain settings. The workflow uses a localhost preview during development; it does not demonstrate offline model inference or a self-hosted deployment.
