Logto provides a complete authentication and authorization infrastructure that eliminates the complexity of implementing OIDC, OAuth 2.1, and SAML from scratch. It ships with pre-built, customizable sign-in and sign-up flows covering email, phone, social login providers, Google One Tap, passwordless magic links, and multi-factor authentication. The admin console offers visual configuration of these flows without writing code, while the underlying protocol compliance ensures compatibility with any OIDC-reliant service.
For SaaS builders, Logto's multi-tenancy model supports organization-level authentication where each tenant can have its own SSO configuration, branding, and role-based access control policies. Enterprise SSO integration via SAML and OIDC connects to corporate identity providers like Okta, Azure AD, and Google Workspace. The RBAC system supports both API-level and UI-level permissions, with scopes that flow through access tokens for zero-trust authorization at every service boundary.
SDKs are available for over 30 frameworks and platforms including React, Next.js, Angular, Vue, Express, Go, Python, Ruby, Flutter, iOS, and Android, with each SDK handling the full authentication lifecycle from login to token refresh. The open-source edition self-hosts via Docker and includes the complete auth server, admin console, and connector system. Logto Cloud offers a managed alternative with automatic scaling, built-in analytics, and webhook integrations for teams that prefer not to operate auth infrastructure.
