What is the best open source oauth platform?

I would prefer something I can run locally and in a docker container, but I will definitely consider cloud based provider. Just for background I have been using azure b2c so I do need something user facing. Any input would be awesome :]

I'm a big fan of Firebase Auth, completely cloud based, but so fricken easy to use, basically out of the box functionality. Plus, a nice selection of oAuth providers built in, and integration with the rest of the Firebase services.


Keycloak is my choice. It 's open source and available in DockerHub

  • keycloak as a java based full blown service
  • auth0 as SAAS
  • IdentityServer as an SDK but can work as a ready out of the box solution. The difference with keycloak is that as an SDK it allows you to embed it in your service.

Hi, I've worked with Identity Server 4 which is open source and can be hosted anywhere.
I would definitely suggest it.
