Casdoor vs WSO2 Identity Server

Two open-source identity servers, two operating models

WSO2 Identity Server is an Apache-2.0 identity server with a commercial subscription for support. Casdoor is an Apache-2.0 identity provider with a managed cloud and a flat price. Both cover SAML, OIDC and SCIM; the difference is the extension model, the operations and the bill.

Why teams choose Casdoor

Smaller operational surface

One Go service and a database, without a Java application server or a product-specific extension model.

Flat price

A dedicated managed instance from $6.67/month billed yearly with unlimited users, or self-host the same code for free.

CAS, LDAP and RADIUS included

One product covers web SSO and the protocols older applications and devices still use.

Authorization included

Casbin RBAC, ABAC and ACL are built in, next to the identities.

When WSO2 Identity Server may fit better

You need a vendor support contract and an established enterprise IAM product with a large Java extension ecosystem.
Your organization already runs WSO2 middleware and wants identity from the same vendor.

Moving from WSO2 Identity Server to Casdoor

Applications move over as SAML or OIDC clients with new metadata. Users and groups can be exported through SCIM or a database export and imported into Casdoor, then applications move one at a time. Keep the WSO2 deployment running until the last application is cut over.
