WorkOS Review

WorkOS sells the part of authentication that lands when a startup signs its first enterprise customer: SAML or OIDC single sign-on, SCIM directory sync and audit logs, delivered through one API. Its pricing is unusual, because the user count is free until 1 million and the money sits entirely in the per-connection line. Toolradar data: of the 103 identity and access tools we evaluated for the identity and access ranking, updated 16 October 2026, 58% are free, freemium or open source, and WorkOS sits in the full browse list rather than the top 30, where Auth0 ranks 14th, Clerk 15th and Stytch 20th.

WorkOS is an enterprise-readiness API for SaaS products, with AuthKit as its user-facing login layer. AuthKit, the User Management product, bundles a hosted UI, email and password, social login, magic link, passkeys, MFA, organizations, role-based access control and session management, all from one integration. Around it sit the products enterprises ask for in security questionnaires: Single Sign-On that works with any SAML or OIDC identity provider, Directory Sync for SCIM provisioning, Audit Logs with SIEM streaming, and Radar for bot and fraud checks. The tool profile is on Toolradar's WorkOS page, and the wider category sits in our authentication pricing comparison.

You integrate AuthKit once, through the SDK for your framework or the CLI installer, and every sign-in method is a configuration switch rather than a new integration. When a customer asks for SSO, you create an organization for them and send their IT admin a setup flow; WorkOS handles the handshake with their identity provider behind an OAuth 2.0 style interface, so Okta and Entra look identical to your code. Each configured identity provider is one connection, and each connection is one line on the invoice, which is why the finance team sees WorkOS grow with the customer list rather than with sign-ups. Directory Sync works the same way per connection, pushing user and group changes from the customer's directory into your app. The rough edge is commercial, not technical: a connection costs the same whether the customer has 20 users or 20,000.

WorkOS publishes pay-as-you-go prices and a custom Annual Credits plan; there is no monthly subscription and no seat fee. AuthKit is free for the first 1 million monthly active users and then costs $2,500 a month for each additional million. Single Sign-On and Directory Sync are each priced per connection: $125 a month each for 1 to 15 connections, $100 for 16 to 30, $80 for 31 to 50, $65 for 51 to 100, and custom above that. Prices checked October 17, 2026 on WorkOS pricing.

Scenario one: a B2B SaaS with 10,000 monthly active users and 10 enterprise customers on SSO. WorkOS costs $1,250 a month, all of it SSO connections, since the users are free. Clerk Pro costs $700 on monthly billing: $25 for the plan, one connection included, and nine more at $75 each. Stytch costs $625, because its pay-as-you-go tier includes 10,000 users and five SSO or SCIM connections, leaving five to buy at Stytch's per-connection rate, which equals WorkOS's entry rate. Auth0 B2B Essentials costs $2,800: $2,100 at 10,000 users with three connections included, plus seven more at Auth0's per-connection rate. Descope needs Growth at $799 a month billed annually, the first plan with 10 SSO connections, and that plan also covers 25,000 users.

Scenario two: 100,000 users and 20 SSO customers. WorkOS costs $2,375: 15 connections at the top rate and five at the second band. Clerk comes to $2,450, which is $1,025 for the plan with 100,000 retained users plus 19 extra connections at Clerk's flat rate. Auth0 publishes no price at 100,000 users, Stytch publishes no per-user overage rate, and Descope's Growth plan stops at 25,000 users, so those three are quotes at this size. The two published bills differ by the price of one Clerk connection, and WorkOS pulls ahead only once connections pass 15 and its ladder steps down.

The ladder is the thing to model before you sign. A product with 50 customers on SSO pays 15 at the entry rate, 15 at the second band and 20 at the third, which is $4,975 a month on WorkOS against $3,675 of connection fees on Clerk at its flat rate. WorkOS answers that with the custom quote above 100 connections and the Annual Credits plan, so a high-connection product should negotiate rather than pay list.

WorkOS suits a B2B SaaS team that sells to a small number of large enterprises and wants SSO, SCIM and audit logs from one vendor without paying per user. A product with 200,000 free-tier users and eight enterprise accounts is its ideal customer: the users cost nothing and the eight connections are a predictable line. It also suits a team that already has login working and only needs the enterprise layer, since SSO and Directory Sync can be bought without moving to AuthKit. Skip it if your enterprise customers are many and small, because 50 SSO connections cost $4,975 a month at list and Clerk's flat per-connection fee is lower from the second connection onward. Skip it too if you want everything inside your database vendor; Supabase and Firebase bundle authentication with hosting and storage, and the backend as a service ranking compares those bundles.
