What alternatives to Auth0 are worth looking into? Between this P0 (with no ability to check the status or file a ticket) and the Okta acquisition, I hesitate to continue using Auth0 as the default when spinning up new web apps.
(famous last words)
Outside of that they Ory ecosystem is really nice. We user Hydra, which is not a drop-in Oauth2 server but requires you to write several of the components yourself.
Just looked. Java, Wildfly, Infinispan, Hibernate + A DB, network multicast if you want a cluster, your own separate load balancer, etc. So, a fairly large time investment if you aren't familiar with all of that.
