Overview
Logto is an open-source authentication platform for SaaS and AI apps. It handles OIDC, OAuth 2.1 and SAML for you, with multi-tenancy, enterprise single sign-on and role-based access control built in. It can be self-hosted or used through Logto Cloud.
What it does well
Logto provides pre-built sign-in flows with customisable interfaces and SDKs for more than 30 frameworks. It supports organisations for multi-tenant apps, enterprise SSO, permissions, and works out of the box with the Model Context Protocol and agent-based AI architectures.
Why it’s in the collection
Logto takes the pain out of building secure, standards-based authentication without locking you into a per-user pricing model. It is MPL-licensed and can run on your own infrastructure.
