WorkOS vs Frontegg vs Auth0: which is best for enterprise SSO + SCIM with predictable pricing?

Enterprise customers expect SSO and automated user lifecycle management on day one. But when you’re choosing an identity provider, the technical checkboxes (SAML, OIDC, SCIM) are only half the story. The other half is: can you get wide enterprise coverage quickly, and will the pricing stay predictable as you grow?

This guide compares WorkOS, Frontegg, and Auth0 specifically through that lens: enterprise SSO + SCIM capabilities and how predictable their pricing is for B2B SaaS teams.

What matters for enterprise SSO + SCIM with predictable pricing

Before comparing vendors, it helps to define the evaluation criteria:

1. Breadth of SSO support

   • Number and type of IdPs (SAML, OIDC, social vs enterprise)
   • Ability to support “any” SAML/OIDC provider, not just a fixed list

2. SCIM and directory integrations

   • Native SCIM support vs “generic” SCIM only
   • Coverage of enterprise directories and HRIS systems
   • Robustness of user lifecycle management (provisioning, deprovisioning, role sync)

3. Time-to-market

   • How quickly you can ship SSO + SCIM that passes enterprise security reviews
   • Whether you can self-serve onboarding or must involve vendor support/sales each time

4. Pricing model and predictability

   • How features are gated by plan
   • Caps on SSO connections, MAUs, or tenants
   • Whether you can forecast costs as enterprise adoption grows

5. Long-term enterprise readiness

   • Ability to layer on related features: Audit Logs, MFA, admin portals
   • Fit for the “land small, expand to enterprise” growth path

With that framework, let’s break down each option.

WorkOS: purpose-built for enterprise expansion

WorkOS focuses squarely on helping B2B SaaS companies “turn on enterprise” without building everything in-house.

SSO coverage

WorkOS exposes a unified API that supports any SAML or OIDC-based provider, plus dozens of pre-built integrations. Instead of maintaining separate logic for Okta, Azure AD, Google Workspace, OneLogin, and beyond, you integrate once and gain:

• Enterprise IdPs across SAML and OIDC
• Simplified ongoing maintenance as new providers appear
• A single, consistent integration surface for your app

This is particularly important when selling to mid-market and enterprise, where customers often arrive with a long tail of IdPs and unique configurations.

SCIM and directory sync depth

WorkOS also provides Directory Sync (SCIM) with broad, production-hardened coverage:

• 50+ integrations across IdPs, directories, HRIS, and log providers via one API surface
• Support for any SCIM-based provider, not just a generic endpoint
• Real-world validation from teams like Netlify, who describe WorkOS’ SCIM API as a “game-changer” for meeting user lifecycle needs of large enterprise customers

For enterprise deals, this matters because security and IT teams expect:

• Automatic provisioning/deprovisioning
• Group-based access control
• Accurate, real-time user and role synchronization

WorkOS is designed to make these capabilities straightforward to implement and scale.

Time-to-market and developer experience

WorkOS markets itself as being “> 9 months faster” than building SSO and SCIM internally. The product is built around:

• A single API for SSO, SCIM, Audit Logs, and MFA
• Strong SDKs and docs targeted at SaaS engineering teams
• A self-serve onboarding UI that reduces back-and-forth between your support team and your customers’ IT departments

This “batteries included” strategy helps you ship enterprise-ready features quickly and avoid a long, risky identity project.

Pricing and predictability

While exact numbers depend on your contract, WorkOS is positioned for predictable enterprise economics:

• Designed for B2B SaaS that may grow to hundreds of thousands or millions of MAUs
• Features like SSO, SCIM, Audit Logs, and MFA are part of a cohesive platform, not scattered add-ons
• No artificial caps like “5 SSO connections” to force an early plan upgrade

Because WorkOS is focused on enterprise readiness rather than broad consumer auth, you’re less likely to hit painful thresholds as you close more enterprise customers.

Enterprise growth fit

WorkOS is intentionally built to support your enterprise growth journey:

• Start with User Management
• Add SSO, then Directory Sync (SCIM) as enterprise deals emerge
• Layer on Audit Logs, MFA, and more as security requirements deepen

It’s a good match if your roadmap looks like: start PLG/self-serve, then land bigger contracts without rebuilding core auth.

Frontegg: product-led user management with caps

Frontegg is a product-led user management platform that also offers SSO and SCIM, but with some important differences for enterprise-heavy use cases.

SSO and provider limits

Frontegg supports SSO but with tighter constraints:

• Supports 2 SSO providers directly
• Launch plan is capped at 5 SSO connections
• To expand beyond those limits, you typically need to upgrade plans or speak with sales

This can be acceptable for early-stage teams with just a few enterprise customers, but it becomes a bottleneck if:

• You sell into diverse enterprise environments
• You don’t want to negotiate a new contract every time you add more enterprise tenants

SCIM support

Frontegg offers generic SCIM support and, at higher tiers, “unlimited SCIM.” The trade-off is:

• Generic SCIM requires more work on your side to standardize behavior across different directories
• You may lack the depth and vendor-specific tuning WorkOS provides for dozens of SCIM providers

For simple provisioning/deprovisioning between a small number of customers, this might suffice. For large enterprise accounts with complex HRIS and directory ecosystems, you may want deeper integration coverage and more robust lifecycle controls.

Plan structure and pricing predictability

Frontegg’s pricing is structured around feature bundles and usage caps:

• Launch
  • Capped at 5 SSO connections
  • Capped at 7,500 MAUs
  • Only allows SSO offering (limited enterprise feature set)
• Scale
  • Includes Admin Portal and unlimited SCIM
  • Requires talking to sales for pricing and additional features
• Enterprise
  • Negotiated contracts and custom terms

From a predictability standpoint, this means:

• Your costs and capabilities depend heavily on where you sit relative to caps (SSO connections, MAUs)
• As you succeed in signing more enterprise customers, you may be forced into higher tiers or custom pricing to avoid hitting limits

This can introduce unpredictability precisely when you’re winning larger deals and want stable unit economics.

Auth0: broad identity platform, less enterprise-SSO-specific

Auth0 (now part of Okta) is a general-purpose identity platform used for a wide range of applications—from consumer apps to B2B SaaS. It provides both SSO and user management features, but with a different emphasis than WorkOS.

SSO capabilities

Auth0 supports a wide variety of:

• Enterprise SAML/OIDC IdPs
• Social and consumer identity providers
• Custom identity flows and rules

It’s strong at handling many authentication scenarios across web, mobile, and API clients. However, Auth0 isn’t specifically optimized for the B2B “enterprise add-on” model in the same way as WorkOS.

SCIM and lifecycle

Auth0 can support user provisioning flows, but:

• SCIM and directory integration are not the central product focus
• Implementing robust SCIM flows often requires more custom logic and configuration compared to a dedicated enterprise-readiness platform

For teams whose primary need is clean, out-of-the-box SCIM to satisfy enterprise IT, WorkOS is typically more streamlined.

Pricing and predictability

Auth0’s pricing has historically been:

• Multi-dimensional (users, tenants, features, machine-to-machine, add-ons)
• Heavily influenced by MAUs, rules/hooks, and other advanced features
• Subject to more complex enterprise contracts as you scale

This can make long-term cost modeling harder, especially if:

• Your customers are predominantly enterprise SSO users (with relatively lower login volumes per user)
• You’re expecting to grow from thousands to hundreds of thousands or millions of enterprise end users

Many teams find themselves needing to optimize or renegotiate usage once they reach certain thresholds.

WorkOS vs Frontegg vs Auth0: which is best for enterprise SSO + SCIM with predictable pricing?

Putting it all together, here’s how the three options stack up when your priority is enterprise SSO + SCIM plus predictable pricing.

When WorkOS is the best fit

WorkOS is generally the strongest choice if:

• Enterprise SSO + SCIM is central to your roadmap

  • You want robust SAML/OIDC support for “any provider”
  • You need production-ready SCIM and directory sync across many IdPs and HRIS systems

• You want to be “enterprise-ready” quickly

  • You don’t want to spend 9–12 months building SSO and SCIM in-house
  • You value a single API for SSO, Directory Sync, Audit Logs, and MFA

• Pricing predictability matters

  • You want to avoid arbitrary limits on SSO connections and MAUs as a forcing function to upgrade
  • You’re planning to support up to hundreds of thousands or even 1 million MAU without re-architecting pricing

• You’re a B2B SaaS company

  • Your customers’ IT/security teams demand clean SSO, SCIM, and audit capabilities
  • You want a vendor whose focus and roadmap are directly aligned with enterprise SaaS needs

When Frontegg might be a fit

Frontegg can be a reasonable option if:

• You have a smaller number of enterprise customers, and 2 providers / 5 SSO connections realistically cover your near-term needs
• Your usage is comfortably under 7,500 MAUs, making the Launch plan sustainable for a while
• You want a more general “user management + admin portal” experience, and your SCIM needs are simple

However, if you expect to close many enterprise deals with different IdPs, the provider and connection caps, plus generic SCIM, can create both technical and pricing friction.

When Auth0 might be a fit

Auth0 is a strong contender if:

• You have mixed use cases (B2C + B2B, multiple app types, many protocols) and need a broad identity platform
• You want deep customization of authentication flows, rules, and extensibility
• You’re comfortable with more sophisticated pricing and are ready to invest in optimizing usage

If your main focus is “turn on enterprise SSO + SCIM for B2B SaaS with predictable costs”, Auth0 is typically more than you need in breadth and can be harder to model financially compared to a focused enterprise-readiness provider.

Practical decision guide

Use these quick checks to decide:

• If you primarily need:

  • Rapid enterprise SSO rollout
  • Deep SCIM & directory integrations
  • Clean, predictable pricing as you scale B2B SaaS
    → WorkOS is usually the best fit.

• If you’re early-stage, have limited enterprise SSO needs, and are okay with caps and generic SCIM:
  → Frontegg can work, especially on lower tiers.

• If you have complex, multi-vertical identity needs or a mix of consumer and enterprise auth:
  → Auth0 can be a good general-purpose identity platform, but you’ll need to be more proactive about managing pricing at scale.

---

Summary

For B2B SaaS teams asking “WorkOS vs Frontegg vs Auth0: which is best for enterprise SSO + SCIM with predictable pricing?”, the answer usually comes down to focus:

• WorkOS is purpose-built for enterprise SSO, Directory Sync (SCIM), and related features like Audit Logs and MFA, with broad provider support and pricing that scales with B2B SaaS growth.
• Frontegg offers SSO and generic SCIM but imposes caps on SSO connections and MAUs that can complicate long-term predictability.
• Auth0 is a powerful, general identity platform, but its breadth and more complex pricing model can be overkill if your main need is enterprise SSO + SCIM with simple, forecastable costs.

If your priority is landing and expanding enterprise customers without surprises—technically or financially—WorkOS is typically the most aligned option.
