Why we included this project
Logto is a self-hosted identity service for teams that would rather rely on a maintained authentication foundation than build login flows from scratch. It covers sign-up, sign-in, passwordless, and multi-factor login, then layers on the enterprise pieces that are genuinely painful to implement yourself: SAML and OIDC single sign-on, multi-tenancy, and role-based access control. Customizable sign-in pages and SDKs for dozens of frameworks keep your engineers working on the product instead of auth plumbing. The same access-control primitives apply whether you ship a classic SaaS app or an AI agent platform, so teams get a dependable dependency rather than a differentiator they must babysit in-house.
