AUTHENTICATION & IDENTITY

Logto

Open-source OIDC identity infrastructure — cloud or self-hosted, token-based pricing.

Why It Matters

Logto is one of few platforms that offers genuine choice between cloud-managed and self-hosted deployment without feature restrictions. Built on OAuth 2.1 and OIDC standards, it provides protocol-compliant identity infrastructure with token-based pricing on cloud — 50K free tokens, then $0.08/100 extra.

What It Actually Does

Every capability explained in plain English — so you know exactly how Logto handles authentication, user management, and security for your product.

Omni Sign-In Experience

Multi-app and cross-domain sign-in with a beautiful, customizable hosted UI. Password, passwordless (email/SMS), social login, enterprise SSO, and MFA — all from one unified experience. Custom CSS, bring-your-own-UI option, app logo, favicon, and dark mode support.

What This Means For Your Business

One beautiful login page that automatically handles passwords, social login, enterprise SSO, and two-factor auth. Customize it with your brand or build your own UI entirely.

Organizations (Multi-Tenancy)

Multi-tenant organization management with custom roles and permissions per org, member invitations via Management API, JIT (just-in-time) provisioning, and organization-level MFA enforcement. Unlimited organizations and users per org on Pro plan.

What This Means For Your Business

Build SaaS products where each business customer gets their own space with team management, roles, and permissions. New users are automatically provisioned when they sign in.

Enterprise SSO (SAML & OIDC)

Enterprise SSO add-on supporting SAML 2.0 and OIDC identity providers. Connect Okta, Azure AD, Google Workspace, and any compliant IdP. $48/connector/month on Pro plan.

What This Means For Your Business

Enterprise customers log in through their company identity provider. Logto supports all major providers and handles the complex SAML/OIDC protocols for you.

Best For

Product types and use cases where Logto delivers the most value — based on its feature set, compliance story, and multi-tenant capabilities.

SaaS & Multi-App Products

Strong Fit

Omni sign-in enables single identity across multiple apps and domains. Organizations with RBAC handle multi-tenancy. OIDC/SAML app support lets Logto serve as your own identity provider.

Privacy-Sensitive Products

Strong Fit

Self-hosted option for full data sovereignty. Cloud available in EU, US, AU, and JP regions. SOC 2 Type II certified. Data isolation and encryption at rest. No vendor lock-in with open-source core.

Developer Platforms

Strong Fit

M2M auth, personal access tokens, OIDC/OAuth third-party apps, and a comprehensive Management API make Logto ideal for platforms that need to issue auth to third parties.

Enterprise (Self-Hosted)

Good Fit

Self-hosted Docker deployment with enterprise SSO, SAML apps, and organizations. However, self-hosted version requires your own infrastructure team for maintenance and scaling.

Startups & MVPs

Good Fit

50K MAU free on cloud, unlimited on self-hosted. Token-based pricing is affordable. However, the add-on pricing model (MFA $48, RBAC $32, Organizations $48) can add up quickly.

Consumer Apps

Good Fit

Social login, passwordless, and beautiful sign-in UI cover consumer needs. Mobile SDKs for React Native, Flutter, iOS, and Android. Token-based pricing scales predictably.

Honest Trade-Offs

No technology is perfect. Here are the real limitations of Logto — so you make an informed decision, not a surprised one.

Add-On Pricing Adds Up QuicklyHigh

MFA ($48), RBAC ($32), Organizations ($48), Enterprise SSO ($48/connector), and Advanced Security ($48) are all separate add-ons. A fully-featured Pro setup can easily exceed $200/month before token costs.

No Passkey Support YetMedium

Passkey/WebAuthn as a first-factor authentication method is listed as 'coming soon.' In a market where Clerk, WorkOS, and Better Auth already support passkeys, this is a notable gap.

Token-Based Pricing ComplexityMedium

Pricing is based on tokens (access tokens) rather than straightforward MAU. Understanding how tokens relate to actual users requires consulting documentation — less intuitive than per-user pricing.

Self-Hosted Requires Docker ExpertiseMedium

Self-hosted deployment via Docker is powerful but requires infrastructure knowledge. Database management, TLS configuration, and scaling are your responsibility.

Smaller Ecosystem Than Auth0/ClerkLow

With 9K GitHub stars and a growing community, Logto's ecosystem is smaller than Auth0 or Clerk. Fewer third-party tutorials, Stack Overflow answers, and community resources.

No Built-In Rate LimitingLow

Unlike Clerk or Better Auth, Logto doesn't include built-in rate limiting for authentication endpoints. You rely on Cloudflare/Azure firewall protections or implement rate limiting in your infrastructure.
