## Where their work shows up

[Auth0](https://startwithidentity.com/vendors/ciam/auth0/) established the pattern most modern [CIAM](https://startwithidentity.com/guides/fundamentals/what-is-ciam/) platforms still follow: developer-first documentation, extensibility through hooks into the authentication pipeline, and a free tier that let teams start without procurement.
