I have developed SaaS using MERN and FastAPI
I used OpenAI APIs like GPT3.5 and Dalle2
SaaS with Subscription paywall using the Stripe
Users can subscribe and use them
I have also provided free services for it no need to subscribe
I can also set a rate limit for free services from FastAPI
Like 200 calls per month etc
I deployed using the GCP with CI CD pipeline just push code to GitHub It will deploy automatically
Also used Google Domain name service
Here is the Demo
