SuperTokens API
SuperTokens — open-source, self-hostable authentication platform with pre-built UI components and backend SDKs for session management, social login, MFA, and enterprise SSO.
Score Breakdown
⚙ Agent Friendliness
🔒 Security
Apache 2.0 open source — fully auditable. Self-hosted gives complete data sovereignty. Rotating refresh tokens prevent session hijacking. No SOC2 certification. GDPR compliant for cloud.
⚡ Reliability
Best When
You need open-source, self-hosted authentication with full data control, no per-MAU pricing, and backend SDK integration for Python, Node, Go, or Java services.
Avoid When
You want zero-infrastructure auth — managed platforms like Auth0 or Clerk are significantly simpler to operate.
Use Cases
- • Agents implementing authentication in self-hosted environments with full data sovereignty and no vendor lock-in
- • Session management automation — agents creating, validating, and revoking user sessions via SuperTokens Core API
- • User management — agents provisioning, updating, and deleting users programmatically through the SuperTokens management API
- • Multi-tenancy with per-tenant auth config — agents creating tenant-specific SSO and auth flows for B2B products
- • Token refresh automation — agents handling JWT rotation and session extension without user re-authentication
Not For
- • Teams needing zero-infrastructure auth — use Auth0, Clerk, or Descope for fully managed auth
- • Enterprise SSO without self-hosting capability — managed auth providers have better enterprise support
- • Teams without backend development resources — SuperTokens requires backend SDK integration
Interface
Authentication
Core API key for SuperTokens Core communication (backend-to-core). User JWTs issued by SuperTokens for end-user auth. Self-hosted instances manage their own API keys.
Pricing
Open source core under Apache 2.0 — self-hosted is completely free. Cloud tier for managed hosting. Enterprise features (SAML, multi-tenancy) available on paid plans.
Agent Metadata
Known Gotchas
- ⚠ SuperTokens Core runs as a separate service — agents must ensure Core is running before SDK operations
- ⚠ Self-hosted Core requires PostgreSQL or MySQL — in-memory mode is development-only, not production
- ⚠ Session validation happens against Core — network latency to Core affects every authenticated request
- ⚠ Multi-tenancy is an add-on feature — base setup does not include tenant isolation without configuration
- ⚠ JWT public keys are served by your backend, not SuperTokens — key distribution is developer responsibility
