WorkOS is a unified set of building blocks for quickly adding enterprise-grade features to your application. It solves the tedious and complex problem of integrating with dozens of identity providers, managing user provisioning across directories, and implementing compliance-ready audit logging — all through a single API. Instead of building and maintaining integrations for every enterprise customer, developers use WorkOS to ship features like Single Sign-On (SSO), directory sync, and role-based access control in a fraction of the time.
WorkOS is built for B2B SaaS developers and engineering teams who need to make their app enterprise-ready. It is ideal for startups and scale-ups that need to win large accounts quickly. It is not a fit for consumer-only apps that don't require enterprise identity federation, or for non-technical users who want a no-code solution.
Add SSO to your app so that enterprise users can sign in with any SAML or OIDC provider (Okta, Azure AD, OneLogin). Sync users and roles from corporate directories like Google Workspace and Microsoft Entra ID. Protect sign-ups and logins from bots and fraud with Radar. Stream audit events to SIEM tools like Splunk for SOC 2 and other compliance requirements. Use AuthKit to drop in a customizable authentication UI that supports social login, magic auth, and MFA.
