Logto

Logto is an open-source authentication and authorization platform built for SaaS, AI products, and modern developer teams. It helps teams add secure sign-in, sign-up, user management, organization support, and access control without building identity infrastructure from scratch. The project is based on standards such as OIDC, OAuth 2.1, and SAML, making it suitable for web apps, mobile apps, APIs, machine-to-machine access, and enterprise integrations. It supports multi-tenancy, role-based access control, enterprise SSO, MFA, social login, and customizable authentication experiences. Developers can integrate it through SDKs for many popular frameworks and languages. Logto is especially useful for teams that need production-grade identity features while keeping control over branding, architecture, and deployment options.
