Logto is an open-source identity platform that handles sign-in, single sign-on, and organization management for web, mobile, and AI applications. Teams add authentication with its hosted pages or APIs instead of building login, SSO, and access control themselves, then run it as self-hosted open source or as the managed Logto Cloud service.[1][2][3]
Quick verdict
SaaS teams that need sign-in, enterprise SSO, and multi-tenant organization management without building identity in-house benefit most from Logto. Its OIDC and OAuth foundation, social and enterprise SSO connectors, and role-based access control with organizations cover the standard application-authentication workflow, self-hosted or on Logto Cloud. The constraint is operational and commercial: self-hosting needs PostgreSQL, Redis, and container operations, while SSO, extra tenants, and higher support tiers raise the Cloud bill. If you want open-source control over identity with a managed escape hatch, choose Logto; if you want a fully managed service with no infrastructure of your own, choose Auth0 instead.[1][2][3][4]
Key features
OIDC and OAuth sign-in Authenticate users over the open OIDC and OAuth standards, so existing identity libraries and clients interoperate without proprietary protocols.[1][2]
Social sign-in connectors Offer Google, GitHub, and other identity providers beside password and passwordless options through a documented connector catalog.[1][2]
Enterprise SSO Connect customer identity providers over OIDC, SAML, Google Workspace, Okta, and Entra ID, billed as a paid add-on on Cloud plans.[1][2]
RBAC with organizations Model roles and API-resource permissions per tenant, which gives multi-tenant SaaS products isolated membership and access control.[1][2]
MFA and passkeys Add a second factor to sign-in flows, including passkey support, for accounts that need more than a password.[1][2]
Self-hosted open-source core Run the MPL-2.0 core on your own infrastructure with Docker Compose or the Logto CLI against PostgreSQL and Redis.[1][2]
Managed Logto Cloud Skip operations with Free, Dev, and Pro plans carrying MAU, tenant, and SSO metering plus EU and US data-location options.[1]
Management and Experience APIs Drive users, roles, and organizations from code and build custom-branded sign-in flows, with SDKs covering web, iOS, and Android.[1]
Who will love it
SaaS teams shipping B2B authentication: enterprise SSO plus per-tenant organizations and RBAC map directly onto customer-facing login requirements.[1][2][3]
Developers who insist on self-hosting identity: the MPL-2.0 core runs on their own Postgres and Redis, keeping user data inside infrastructure they control.[1][2]
Cost-staged startups: the free OSS core and the $0 Cloud tier defer identity spending until MAU, tenants, or SSO force a paid plan.[1][2]
Who should avoid it
Teams with no one to run infrastructure: self-hosting assumes Docker, PostgreSQL, and Redis operations, and the managed alternative is a paid plan once usage grows.[1][2]
Buyers wanting SSO on the free tier: enterprise SSO is a paid add-on, so pilots that must prove customer SSO before paying should look elsewhere.[1]
Non-technical site owners: everything from SDK integration to role modeling assumes developers; a no-code membership plugin fits them better.[1][2]
Alternatives and compatibility
Auth0 is the incumbent in the published catalogue relationship and Logto positions itself as the open-source Auth0 alternative, which decides the control question for buyers choosing between managed and runnable identity.[1]
Auth0 fits teams that want fully managed customer identity with no infrastructure and guided setup.[1][2]
Keycloak and Authentik fit teams comparing self-hosted OIDC and SSO servers; switching identity providers is SDK, connection, role, and user-migration work, not data export.[1][2]
