12 Best Auth0 Alternatives in May 2026

Auth0's extended free tier reflects Auth0's continued enterprise dominance in customer identity — now part of Okta and the standard "auth-as-a-service" choice for organizations with diverse authentication needs. Auth0's differentiator is the breadth of standards support (OAuth, OIDC, SAML, SCIM), the Universal Login UX flexibility, and the deep integration ecosystem expected in enterprise RFPs.

For modern alternatives, Clerk has captured significant SaaS-startup mindshare with cleaner DX, pre-built React components, and B2B Organizations features. WorkOS targets enterprise SSO specifically (SAML, SCIM, audit logs) — frequently used alongside Clerk for B2B SaaS. Stytch targets passwordless authentication specifically with strong UX for magic links and OTP. Supabase Auth and Firebase Authentication target broader BaaS-bundled authentication. PropelAuth targets B2B-multi-tenant authentication specifically. Frontegg competes with PropelAuth on B2B. Descope is a newer Auth0-alternative with visual workflow builder. FusionAuth offers self-hostable authentication with generous free tier. Ory Network and Keycloak are open-source self-hosted alternatives. For specifically passwordless workflows, Stytch and Clerk lead. For specifically SAML SSO without full auth, WorkOS and BoxyHQ Jackson focus on this slice. AWS Cognito is the AWS-native alternative. The Auth0 free tier remains useful but pricing escalates significantly past 1,000 active users — for SaaS startups, Auth0's pricing is often the trigger to evaluate alternatives. For consumer apps with high MAU, Auth0 quickly becomes expensive; Supabase Auth or Firebase Auth are the cost-conscious alternatives. The practical decision: Clerk for modern B2B SaaS with polished React components; Supabase Auth for Postgres-anchored startups; WorkOS for enterprise SSO add-on; Auth0 when enterprise expectation or specific feature breadth matters; Stytch for passwordless-first; PropelAuth or Frontegg for B2B-multi-tenant; FusionAuth for self-hostable.
