Auth Platforms With SSO and SCIM in the Base Tier

In 2026, the authentication landscape is shifting, with enterprise SSO becoming more accessible while SCIM becomes the new barrier, often referred to as the "SCIM tax." Traditional providers like Okta, Supabase, and Firebase typically place SSO and SCIM behind higher pricing tiers or charge per connection, whereas newer developer-focused platforms like Clerk, Stytch, and Frontegg are more likely to include these features in their free or base tiers. Clerk stands out for offering SCIM bundled free with each enterprise connection in its base paid tier, while WorkOS provides a pay-per-connection model with broad directory support. Auth0 offers a free tier with limited SSO and SCIM capabilities, but its pricing can escalate steeply with increased usage. The guide provides detailed comparisons, including provider profiles, pricing models, and cost of ownership examples, helping IT decision-makers, startups, and developers navigate the complexities of choosing the right authentication platform based on their specific needs and scale.
