Need help regarding App Integration

I have recently started to use Okta. My requirement was to keep a “sign-in with Okta” button in my application so that users having an Okta account can sign in if the app is assigned to them. I was able to get my app into the OIN network using the Okta developer account. I wanted to turn my “developer account” into a “production account” which brought me to auth0. I am confused between Okta and Auth0.
