SuperTokens
A developer-friendly, self-hostable auth core built for fast integration into existing apps.
80
sovereigntySuperTokens is an authentication solution built to drop into an existing app quickly, with official SDKs for popular frontend and backend frameworks and pre-built session-management, MFA, and passwordless flows. It ships a self-hostable core service plus a managed cloud option, aimed at teams that want Auth0-like integration speed without the recurring per-MAU cost.

PricingFree / self-host for the Apache-2.0 core; a managed SuperTokens cloud and a paid Enterprise tier (SSO/SAML, advanced MFA policies under the ee/ license) are available for teams that want those features or don't want to self-host.

Local-first dataYes
What it does well
- +Genuinely permissive Apache-2.0 core license for self-hosting the base authentication service
- +SDK-first design with strong framework coverage makes initial integration noticeably faster than headless-only alternatives
- +Built-in session-management primitives (rotating refresh tokens, anti-CSRF) are handled for you rather than left to the integrator
- +Free self-hosted core has no MAU cap, unlike Auth0's metered model
Where it falls short
- −Enterprise SSO/SAML and some advanced MFA policies live behind the separately-licensed ee/ directory, not the free core — verify feature-tier fit before committing
- −Smaller community and third-party plugin ecosystem than Keycloak
- −Fewer built-in identity-brokering options (LDAP, legacy enterprise directories) than Keycloak or authentik out of the box
