About

This is the official organization of Logto1.

Logto is the modern, open-source identity infrastructure for SaaS and AI apps.

It takes the pain out of OIDC and OAuth 2.1 and makes it easy to build secure, production-ready auth with multi-tenancy, enterprise SSO, and RBAC.

Logto Cloud

Logto Cloud is the official managed service of Logto.

Built on top of Logto OSS, Logto Cloud provides a fully managed, scalable, and secure service for your authentication and authorization needs:

  • Free tier: Get started with for free up to 50,000 monthly active users. Upgrade to our Pro plan with pay-as-you-go pricing.
  • Scalability: Supports millions of users with no performance concerns.
  • Security: Follows industry best practices for security by default.
  • Zero maintenance: Our team handles the infrastructure, so you don’t have to.
  • No vendor lock-in: You can always switch back to the OSS version at any time.
