Short summary

Dev.to compares SSO/SAML pricing across Auth0, Clerk, WorkOS, and Authagonal at three scale points (1k–50k MAU), exposing a hidden 'feature tax' that can reach $30k/year. WorkOS charges $30k annually for SSO+SCIM alone at 50k MAU, while Authagonal's entire platform costs $3.7k. Auth0 hides SSO costs in a B2B tier premium; Clerk meters per connection.
