Case Study: Replit adds production-ready authentication to its app with WorkOS AuthKit

Replit adds auth in minutes with WorkOS, free for up to 1M active users

Replit, a platform that enables users to quickly build and deploy apps using AI, needed a production-ready authentication solution for the applications created on its service. Their built-in Replit Auth option lacked critical enterprise features like SSO, audit logs, and directory sync, which limited the ability of apps built on Replit to serve business customers. To overcome this challenge, they implemented WorkOS AuthKit.

WorkOS provided a complete authentication layer that was integrated directly into a Replit-generated Node.js app. The solution enabled email/password, social login, passwordless auth, and enterprise SSO without requiring a full rebuild. By using WorkOS, Replit apps gained a secure, scalable auth system with features like MFA and an admin portal, making them immediately ready for production use and enterprise customers.
