Logto

What is Logto?

Logto is an open-source identity solution designed for modern applications, SaaS platforms, and AI applications. It provides developers with authentication and authorization capabilities built on industry-standard protocols including OIDC and OAuth 2.1. The platform enables multi-tenancy support, allowing applications to serve multiple organizations or customer groups within a single deployment. It includes enterprise SSO (Single Sign-On) functionality for seamless user authentication across integrated systems, and Role-Based Access Control (RBAC) for granular permission management. Logto is built with developer experience in mind, offering straightforward implementation of complex identity management features. The open-source nature of the project means source code is publicly available on GitHub, allowing organizations to review the codebase, self-host, and contribute to its development. The solution is well-suited for development teams building SaaS applications, multi-tenant platforms, or AI applications that require authentication without the complexity of managing identity infrastructure from scratch. By handling identity, authentication, and authorization through a single platform, Logto reduces the time developers spend on security implementation and allows them to focus on application-specific features.
