UI-first IAM and SSO platform with comprehensive protocol support
Open-source Identity and Access Management platform with web UI supporting OAuth 2.0, OIDC, SAML, LDAP, WebAuthn, MFA, and multiple authentication protocols for centralized user management.

Casdoor is a comprehensive Identity and Access Management (IAM) and Single-Sign-On (SSO) platform designed with a UI-first approach. Built for developers and IT teams who need centralized authentication without vendor lock-in, it provides a complete solution for managing users, organizations, and access control across multiple applications.
The platform supports industry-standard protocols including OAuth 2.0, OIDC, SAML, CAS, LDAP, SCIM, and RADIUS, enabling seamless integration with existing infrastructure. Modern authentication methods like WebAuthn, TOTP, and multi-factor authentication (MFA) provide robust security, while enterprise integrations with Google Workspace, Active Directory, and Kerberos ensure compatibility with legacy systems.
Casdoor can be deployed via source code, Docker, or Kubernetes Helm charts, offering flexibility for different infrastructure requirements. The platform includes a public API with Swagger documentation and SDKs for multiple programming languages, making integration straightforward. With an active community and Apache 2.0 license, teams gain full control over their identity infrastructure while benefiting from ongoing development and support.
When teams consider Casdoor, these hosted platforms usually appear on the same shortlist.
