Source: https://altcatalog.com/alternatives/auth0/ Category: Authentication & identity providers ## Overview - **Who it's for**: Development teams building consumer (B2C) or business (B2B/SaaS) applications who need production-grade login, MFA, and enterprise SSO without building an identity system in-house — from startups on the free tier up to regulated enterprises needing private cloud deployment. - **What you get**: A hosted authentication platform (Universal Login) with social login, passwordless/magic-link and passkey/WebAuthn support, adaptive MFA, SAML/OIDC enterprise SSO, inbound SCIM provisioning, and B2B Organizations with role-based access control — delivered as a managed cloud service, now part of Okta. - **How it works**: You connect your app via Auth0's SDKs/quickstarts and redirect users to Auth0's hosted Universal Login (or build a fully custom UI with Advanced Customization for Universal Login); Auth0 handles credential storage, social/enterprise identity provider connections, MFA challenges, and issues tokens (JWT/OIDC) back to your application. ## Profile - **License**: Proprietary (verified 2026-07-13) - **Pricing model**: Freemium (verified 2026-07-13) - **Starts at**: $35/mo (verified 2026-07-13) - **Platforms**: Web - **Status**: acquired (verified 2026-07-13) ## Ranked alternatives | # | App | Alt Score | Licence | Platforms | |---|-----|-----------|---------|-----------| | 1 | [FusionAuth](https://altcatalog.com/alternatives/fusionauth.md) | 93 | Proprietary | Windows, macOS, Linux, Web | | 2 | [Ory](https://altcatalog.com/alternatives/ory.md) | 93 | Apache-2.0 | Linux, macOS, Windows | | 3 | [Zitadel](https://altcatalog.com/alternatives/zitadel.md) | 93 | AGPL-3.0 | Linux, macOS, Web | | 4 | [Clerk](https://altcatalog.com/alternatives/clerk.md) | 89 | Proprietary | Web, iOS, Android | | 5 | [Frontegg](https://altcatalog.com/alternatives/frontegg.md) | 89 | Proprietary | Web, iOS, Android | | 6 | [Stytch](https://altcatalog.com/alternatives/stytch.md) | 89 | Proprietary | Web, iOS, Android | | 7 | [Descope](https://altcatalog.com/alternatives/descope.md) | 85 | Proprietary | Web, iOS, Android | | 8 | [WorkOS](https://altcatalog.com/alternatives/workos.md) | 85 | Proprietary | Web | | 9 | [Keycloak](https://altcatalog.com/alternatives/keycloak.md) | 81 | Apache License 2.0 | Linux, Windows, Web | | 10 | [Amazon Cognito](https://altcatalog.com/alternatives/cognito.md) | 78 | ? | Web | | 11 | [Kinde](https://altcatalog.com/alternatives/kinde.md) | 74 | Proprietary | Web | Alt Score = Verified coverage (90%) + Visibility (10%).
