Yes I know Supertokens. One of the key differences is the the grand vision of what I'm building. I want to branch out into other platforms like AWS Cognito for auth(Basically I'll configure the AWS Cognito setup so you don't have to), GraphQL solutions like Hasura, Stripe integration, and I also provide serverless function.

So it is a whole backend set given to you vs Supertokens which is just an auth solution. Think of it like Vercel but for backend.
