WorkOS vs Clerk: Which one is better for B2B?

Clerk and WorkOS are two companies offering authentication services, with Clerk recently repositioning itself as a B2B platform while WorkOS has been focused on enterprise solutions from the beginning. Clerk has introduced features like enterprise SSO and SCIM, but WorkOS has a more comprehensive suite of offerings including a fully functional Admin Portal, tamper-resistant audit logs, and extensive pre-built integrations for identity management. WorkOS's infrastructure is designed for scalability and reliability, offering a 99.99% uptime SLA and extensive support for enterprise identity needs, making it favored by companies like OpenAI and Anthropic. Clerk, on the other hand, has faced reliability issues and lacks some enterprise-ready features, such as a self-serve Admin Portal and comprehensive audit log support. For developers, Clerk offers quick setup for projects within React and Next.js, while WorkOS provides a more extensible and standards-aligned approach suitable for complex, enterprise-level requirements. The pricing models also differ, with WorkOS offering predictable per-customer costs and free user management up to a million users, contrasting with Clerk's model that scales with user count and layers enterprise features as add-ons. The text suggests that while Clerk might be suitable for smaller B2B projects or consumer-facing applications, WorkOS's robust infrastructure and comprehensive feature set make it a better choice for serious enterprise engagements.
