What it is

Build a scalable SaaS using the FastAPI and Authx with ai-template.

Real use case example

"A founder wants to build an automated onboarding system for their new SaaS product. They start by creating a FastAPI application with ai-template, then use Authx for user authentication and Stripe for payment processing. After deploying their application, they receive a user's payment and create a new user account with the required permissions."
