What is SuperTokens?
SuperTokens is an open-source authentication and session-management stack covering email/password, social/OAuth login, passwordless magic links and OTP, multi-factor authentication, and role-based access control. The core is self-hostable at no cost with no user limits; SuperTokens also runs a managed cloud service that is free for up to 5,000 monthly active users, then billed at $0.02/MAU (minimum $100/month), with paid add-ons for MFA, account linking, and multi-tenancy.

Key capabilities
- Self-hosted core: Free, open-source authentication with no MAU limit when you run it yourself.
- Managed cloud: Free up to 5,000 MAU, then usage-priced with a $100/month minimum.
- Add-ons: Paid MFA, account linking, and multi-tenancy features on both deployment models.
Core areas are authentication flows (password, social, passwordless), session management, MFA, and RBAC, deployable self-hosted or as a managed service.
Shortlist SuperTokens if you want to self-host authentication for full data control at zero licensing cost, or want a managed alternative to Auth0/Firebase Auth with a genuinely free tier up to 5,000 MAU.
Compare the self-hosted (free, self-operated) and managed (free-to-5,000-MAU, then metered) paths against your team's ops capacity and expected user growth before committing to one deployment model.
