One line each. Open a row for detail.

What it really isA developer platform from WorkOS, Inc. of APIs for adding SSO, Directory Sync, user management and audit logs to B2B software, priced per product unit.

Our takeWorkOS prices are public: AuthKit is free for the first million users, SSO has four published tiers from $125 to $65 per connection, and add-ons are priced.

SSO costs follow the number of enterprise connections, not end users, and the Annual Credits discounts are not published.

Why we rate itClear published prices and a large free allowance, offset by per-connection growth, separate add-ons and unpublished Annual Credits discounts.

The catchSSO and Directory Sync are per connection and the page prints no billing period beside them; add-ons cost extra; payments are nonrefundable and the free tier can change.
