Open-source local API emulator for CI/CD testing

We've released @workos/emulate, an open-source local WorkOS API server for development and automated testing. Point any WorkOS SDK at the emulator to test your integration without making requests to your live WorkOS environment. You can seed users, organizations, memberships, RBAC, SSO connections, and more so that every test starts from a known state.

@workos/emulate also supports the end-to-end AuthKit experience, including SSO redirect and token exchange flows. It provides interactive login pages for browser tests and simulates WorkOS-compatible signed webhook events. You can also inject validation errors, simulated rate limits, and temporary failures to test unhappy paths and retry logic. Learn more in the GitHub repo.
