Hey there, I'm looking into using Kratos as my companies internal identity management solution. We have a bunch of services we'd like to unify under single sign-in / sign-out. Can you achieve something like that with Kratos alone if the apps are running under completely separate domains? Thanks a bunch!

Domain you mentioned is top-level domain or sub-domain? For now, Kratos supports sub-domain only

it's <http://example1.com|example1.com> and <http://example2.com|example2.com>

hydra would have worked for us, but unfortunately the OIDC Session Management Spec wasn't implemented, so we can't really use Single Sign-Out in our SPA use-case.
We wanted to use Introspection on our APIs and get the tokens on our SPA frontends
