What it does
SuperTokens is open-source authentication (email and password, passwordless, social login, sessions) that you host yourself or use as a managed service.
Who it suits
Teams that want to keep user data on their own servers, or start managed and self-host later.
Price
Self-hosting the open-source features is free, with no user limit. Managed service: free under 5,000 monthly active users, then $0.02 per MAU. Add-ons cost extra on both, for example multi-factor authentication at $0.01 per MAU with a $100 monthly minimum.
