Casdoor

Casdoor is an identity provider and single sign-on server: applications send users to it to sign in, and it returns a verified identity over OAuth 2.0, OpenID Connect, SAML or CAS. The overview describes it as an identity and access management platform, with LDAP and RADIUS for applications and devices that speak only those protocols. Users, applications, sign-in pages and providers are managed in a web admin console. Several organizations can share one installation, and each has its own users, groups, roles, applications and branding.

The project is a single Go program that serves the built frontend on one port, and it runs on a database that the operator connects through conf/app.conf. The server installation guide covers a pre-built binary and a build from source, and the Docker Hub images and a Helm chart are the other routes the project documents. The repository is Apache-2.0 licensed, and the pricing page says Casdoor Cloud is operated by Casbin Inc.

Worth knowing

The server needs a database that the operator provides, and the all-in-one Docker image uses an embedded SQLite file that the project describes as not for production. Casdoor Cloud is a dedicated instance that the project hosts and keeps upgraded, sold on the cloud plans of the pricing page, and self-hosting is listed there as free.
