WorkOS, Auth0, and Stytch are three popular authentication platforms with unique features and pricing models. WorkOS is designed for enterprise readiness, offering a unified interface for multiple integrations, scalable infrastructure, and modern APIs. It's suitable for businesses and teams building real products, providing predictable pricing and a solid foundation for growth. In contrast, Auth0 has unpredictable pricing based on Monthly Active Users, customization limitations, and developer experience trade-offs, making it less appealing to large-scale enterprises. Stytch offers a modern developer-friendly approach with passwordless flows but limited enterprise features and scalability, making it more suitable for B2C or MVP projects. Ultimately, WorkOS is the recommended choice for teams building real businesses, particularly those requiring enterprise-level authentication solutions.
