Case Study: Vercel modernizes Better Auth migrations and enterprise identity with WorkOS

Vercel migrates 4.7 million weekly npm-download Better Auth users to WorkOS

Vercel, a platform company that acquired the open source authentication library Better Auth, faced a challenge for its users. Teams running Better Auth in production had to consider a new governance structure focused on agent identity, while many of them needed to address near-term enterprise requirements like SAML and security questionnaires without owning the full operational burden of their auth infrastructure. This prompted a need for a managed platform solution like that offered by vendor WorkOS.

WorkOS provided a clear migration path for moving users, organizations, and password hashes from Better Auth to its AuthKit user management platform. The solution enabled teams to wire in enterprise-ready features such as Single Sign-On (SAML/OIDC), Directory Sync, and Admin Portal, which are handled as a managed service. This allowed engineering teams to focus on their product rather than identity plumbing, ultimately helping them close enterprise deals without the overhead of managing auth infrastructure.
