What is the best open source oauth platform?

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

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

• 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.

In general checkout this very recent presentation

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.

Hi Fulton, we have a simple cloud-based OAuth solution called Cotter that helps you add passwordless login to your website or app. Some features that might interest you:

• Login using Magic Link or OTP via email, SMS or WhatsApp
• Login to websites using WebAuthn (using TouchID/Windows Hello)
• Login to mobile apps using device-based authentication (FIDO)

I've included links for 5-minutes quickstarts. Let me know if you're interested, we're happy to help.
