Overview

One of the most widely adopted CIAM platforms, known for breadth of features, strong documentation, and a large marketplace of extensions. It covers the full customer-identity surface — social and passwordless login, MFA, SSO, SCIM provisioning, and fine-grained authorization — for both B2C and B2B (organizations) models.

Best for

Teams that want one platform to cover a wide range of identity needs and value mature docs, broad protocol support, and a deep integration ecosystem over the lowest possible bill.
