The developer-first APIs for SAML SSO, SCIM, and Directory Sync — the platform that turns “our IT team requires Okta” from a multi-week migration into a 30-minute integration. Pricing and capabilities verified against workos.com/pricing and the public docs.
There’s a moment in almost every B2B SaaS company’s life cycle when the first real enterprise prospect lands a procurement form on the table and one line on it changes the trajectory of the deal: SAML SSO required. For many founders, that line means weeks of SAML hell — reading metadata XML specs, debugging signed assertions, building an admin portal so the customer’s IT team can configure their identity provider, and discovering that “just plug into Okta” sits on top of a small mountain of standards that nobody enjoys learning under deadline. WorkOS is the platform that argues you shouldn’t have to.
Methodology. This is a research-based overview. We have not personally built production apps with WorkOS; this article synthesizes the company’s documentation at workos.com/docs, public pricing at workos.com/pricing, public user reports, and third-party benchmarks. Last reviewed: May 8, 2026.
WorkOS is a developer-first set of APIs for the auth-and-identity surface that enterprise customers expect. Founded in 2019, the company built its product line around the specific gap between “your basic email-and-password auth” and “the SAML, SCIM, audit-log, RBAC stack a Fortune 500 buyer demands before signing the contract.” The product surface today includes:
The argument WorkOS makes is sharp: enterprise auth (SSO and SCIM) is table stakes for $20K+ ACV deals, and rolling it yourself is not a five-day job. SAML alone has implementation footguns that take weeks to discover — signed assertion validation, certificate rotation, attribute mapping, IDP-initiated vs SP-initiated flows, the per-customer connection model. WorkOS turns that work into an API integration: you call their endpoints, you handle the resulting OIDC-style tokens, and the SAML-specific complexity stays inside their service. Reported integration times on public discussions land in the 30-minute to half-day range for a developer who knows their auth stack, versus one to three weeks for a hand-rolled SAML implementation.
The most striking thing about WorkOS’s pricing posture is the free tier — the company famously runs a campaign called “The SSO Tax,” arguing that vendors who charge a steep premium for SSO are taxing the very customers who need it most. WorkOS’s response: SSO and Directory Sync are free up to 1 million MAU.
That is not a typo. For solo SaaS founders, this collapses the cost objection to zero. You don’t need to gate SSO behind your highest-priced plan to recoup vendor costs — the vendor cost is $0 until you’re bigger than most successful SaaS companies will ever be. Other modules in the WorkOS catalog (Audit Logs, Admin Portal, Fine-Grained Authorization, etc.) are priced per usage; these are typically additive features you adopt as your enterprise sales motion matures, not gating items for the first deal. Always reconcile against the live page; pricing structures shift periodically.
AuthKit is WorkOS’s hosted authentication UI — pre-built sign-in forms, social login buttons, SSO discovery, password-based fallback, and Magic Auth links wrapped into a single drop-in component. The closest comparison is Clerk’s component library, but AuthKit’s posture leans more enterprise: the SSO discovery flow (where a returning user is routed to their company’s identity provider based on email domain) is the central case rather than an edge case.
For founders who want the full hosted-auth experience, AuthKit is the front door. For founders who already have a sign-in UI they like, the underlying APIs (SSO, Directory Sync, Magic Auth) work directly without AuthKit on top.
Where SAML SSO solves “the user can sign in via their company’s identity provider,” Directory Sync solves the bigger sibling problem: “the user list in your app needs to mirror the user list in the customer’s directory, automatically and in real time.” If an employee is added to a group in Okta, they appear in your app with the right role; if they leave the company, they’re deprovisioned.
WorkOS’s Directory Sync implements SCIM 2.0 and supports the major directories: Okta, Google Workspace, Azure AD, JumpCloud, OneLogin, and others. Your app receives webhook events when users are added, updated, or removed; you handle them with the same shape of code you’d use for any other webhook. The customer’s IT admin configures their side through the WorkOS Admin Portal.
Not every user a B2B SaaS sees is on a corporate SSO. Trial signups, individual contributor users at smaller companies, and self-serve customers all need a path that doesn’t involve SAML. WorkOS provides Magic Auth (passwordless email links, similar to the magic-link patterns covered in our Supabase magic link guide) and password-based fallback so you have a complete primary-auth path for non-SSO users alongside the enterprise flows.
That said, WorkOS isn’t typically the right pick as your primary auth layer for a brand-new MVP — the platform’s center of gravity is clearly the enterprise surface. For a solo founder shipping their first paid SaaS, the more common path is Clerk or Supabase Auth for the day-one auth layer, with WorkOS layered in the week the first enterprise prospect mentions SAML. We compare the auth-library landscape in best auth library for Next.js.
The headline pricing is structured around “SSO and Directory Sync free up to 1M MAU.” Around that core, three categories of usage-priced modules show up on workos.com/pricing:
For most solo founders entering their first enterprise deal, the bill stays at $0 for the line items the customer is asking about (SSO, SCIM). Audit Logs may add a small line item once you advertise them as a feature; FGA is typically later-stage.
Three sentences capture the recommended timing for a solo SaaS founder:
The thing to avoid is over-investing on day zero. A solo founder pre-revenue does not need WorkOS — they need any auth at all. Adding WorkOS before there’s an enterprise customer asking for SAML is gold-plating; the value of the platform is exactly that it’s ready when you need it, not that you have to adopt it preemptively.
The timing claims in WorkOS marketing are aggressive but defensible based on public reports: a developer who already has working auth and understands OIDC redirect flows can typically wire up WorkOS SSO in roughly 30 minutes. WorkOS handles the SAML weirdness on its side — you’re calling their API, getting back a normalized user object, and treating it the same way you treat any other authenticated user. Hand-rolled SAML, by contrast, takes one to three weeks the first time and a non-trivial amount of ongoing maintenance. The Admin Portal alone — which lets the customer’s IT admin configure SSO without a support call — saves a meaningful number of hours per enterprise customer.
One of the structural reasons WorkOS is easy to recommend is that adopting it is additive, not replacement. You don’t rip out Clerk or Supabase Auth to add WorkOS. You add an “Sign in with SSO” button to your sign-in screen, route that flow through WorkOS, and let the rest of your auth stack continue to handle email/password and social logins. The two systems coexist; the user object you create from a WorkOS sign-in is the same shape as the user object you create from any other sign-in path.
This is materially different from migrations between general-purpose auth platforms (Clerk to Auth0, for example) where you’re moving the entire user table and re-implementing all the auth flows. WorkOS adoption typically touches only the SSO code path, plus the user-creation flow, plus a settings page where you let admins of paying customers turn on SSO for their organization.
Auth0 is the legacy general-purpose auth platform, now owned by Okta. It does everything — email/password, social, SSO, SCIM, MFA, custom flows. The trade-off is cost: Auth0’s pricing for enterprise features (SSO, SCIM, Audit Logs) historically rises sharply with feature tier and MAU, and the total bill at mid-scale frequently runs an order of magnitude higher than the equivalent WorkOS configuration. Auth0 is the right pick if you want a single vendor for your entire auth surface and you’re willing to pay for it. WorkOS is the right pick if you want enterprise auth specifically without the cost ladder.
Clerk’s Enterprise tier (the custom-priced one we cover in Clerk pricing explained) adds SAML SSO and SOC 2 attestations on top of the polished hosted UI Clerk is known for. The right pick depends on shape: if Clerk is already your day-one auth and your enterprise customer count is small, staying on Clerk Enterprise consolidates vendors. If Clerk is your day-one auth but you’re running a real enterprise sales motion with Directory Sync and Audit Log requirements, the WorkOS-alongside-Clerk pattern is often cheaper and gives you more enterprise-specific surface. We compare general auth options in Clerk vs Auth0.
Stytch B2B is the closest direct competitor — another developer-first platform focused on B2B-specific auth flows including SSO, SCIM, and organization management. The two are genuinely close on capability and pricing posture. Differences land more in DX preferences (SDK shape, dashboard polish, documentation style) than in feature gaps. Both are reasonable picks; the WorkOS “no SSO tax” campaign and the 1M MAU free tier give it the headline edge for solo founders watching cost.
If your target customer is enterprise — if your ICP signs procurement forms with “SAML SSO required” on them — WorkOS is the most cost-effective path to checking that box. The free tier removes the cost objection, the integration time genuinely is 30 minutes for a competent developer, and the Admin Portal collapses your support burden for SSO-customer onboarding to roughly zero. We cover the broader compliance side of enterprise sales in what is SOC 2 compliance and the foundational SSO concepts in what is SSO.
If you’re B2C, low-ACV B2B, or pre-revenue with no enterprise customers in your near-term pipeline, you don’t need WorkOS yet. Stay on Clerk or Supabase Auth (we contrast them in Clerk vs Supabase Auth), ship your product, get to revenue, and add WorkOS the week the first enterprise prospect mentions SAML. The platform is most valuable as the thing that turns a multi-week migration into a half-day integration when the deal is on the line — not as the thing you adopt preemptively.
