About Logto
Logto is an authentication and identity platform for developers. It handles user sign-in, single sign-on and access roles, so your team does not have to build login from scratch.
What it does
Logto gives an app a sign-in layer that supports standards such as OpenID Connect and OAuth 2.1. It can add multi-tenancy, enterprise SSO and role-based access on top of the sign-in flow. A management API lets teams automate user and application setup.
Key features
- Sign-in flows for web and mobile apps
- Single sign-on with SAML and OIDC
- Role-based access control and permissions
- Multi-tenant setup for SaaS products
- Management API and SDKs for many frameworks
Who it's for
Logto fits small product teams that want auth working quickly, and SaaS companies that will later need enterprise sign-on. It also suits AI apps that need clear per-user access rules.
Pricing and good to know
The source code is open source under the MPL-2.0 license, so you can self-host it. The hosted cloud version runs in several regions and includes a free tier of 50K monthly active users, with pay-as-you-go pricing beyond that. Self-hosting means your team runs the database and handles upgrades.
