8 Best SuperTokens Alternatives & Competitors (2026)

Auth0 is a cloud identity platform offering extensive social and enterprise connections plus MFA. Its hosted login pages simplify frontend work but introduce redirect flows and usage-based pricing that grows with active users. SuperTokens differentiates by letting teams self-host on their own infrastructure, avoid per-MAU fees, and keep full control over the authentication database and UI components while still providing comparable passwordless and SSO recipes.

Keycloak is a popular open-source identity server with strong SAML and OIDC support used by many enterprises. It requires managing multiple services and a steeper initial configuration curve. SuperTokens offers a lighter modular architecture, faster 5-minute setup, and tighter framework SDK integration for modern stacks like React and Node without the same operational overhead.

Firebase Authentication provides quick social and email sign-in tightly coupled with Google Cloud services. It excels at mobile apps but can feel limiting for teams wanting full data ownership or complex multi-tenancy rules. SuperTokens runs independently of any cloud provider, supports custom password policies and session limits, and keeps all user data on infrastructure you control.

Clerk focuses on developer-friendly React components and hosted authentication with strong prebuilt flows. While convenient, it relies on Clerk's cloud and usage pricing. SuperTokens gives the same prebuilt UI option plus complete self-hosting freedom, open-source transparency, and no mandatory redirects to third-party domains.

Okta delivers enterprise-grade identity with broad protocol support and governance features at premium pricing. It targets large organizations needing advanced workflows. SuperTokens serves startups and mid-market teams seeking similar SSO and multi-tenancy capabilities at lower cost through open-source self-hosting and simpler integration.

Ory offers modular open-source authentication and authorization services deployable via Docker or Kubernetes. Its many moving parts can increase maintenance. SuperTokens consolidates recipes into fewer components, includes ready-made UI helpers, and emphasizes quicker onboarding for teams already using Node or Python backends.

FusionAuth is a self-hosted auth server aimed at developers who need themes, webhooks and advanced reporting. It provides a full admin UI out of the box. SuperTokens instead prioritizes code-first modular recipes and framework SDKs that integrate directly into existing application codebases with minimal extra services.
