Logto
Modern auth infrastructure for developers

Logto is an open-source authentication and identity platform that provides OAuth 2.1, OIDC, and SAML support along with multi-tenancy, enterprise SSO, and RBAC out of the box. It targets SaaS and AI application developers who need to implement secure auth without building it from scratch. Logto offers both a cloud-hosted service and a self-hostable option, with a free tier supporting up to 50,000 monthly active users.
Logto integrates via SDK with 20+ frameworks and a Management API, providing pre-built sign-in flows, RBAC, multi-tenancy, and enterprise SSO powered by OIDC/OAuth 2.1 and SAML protocols.
