It's unfortunate Auth0 was acquired by them. Have used it from the beginning and it used to be a great product before the Okta acq. Now it's just constant sales emails, expensive pricing, not much new feature launches, most features are very enterprise focused, bunch of bugs, frequent outages.
At this point, one could speculate they are not worth almost at all given they fail to deliver on their primary value proposition. They are not and have not been profitable either, only getting worse: https://finance.yahoo.com/quote/OKTA/financials?p=OKTA
I’m just wondering who in the industry is still stupid enough to stick their neck out for Okta? Why are they getting new customers? Why not go with the other devil you know your cloud provider to offer mostly the same services? What is Okta offering when they seem relatively incompetent compared to the competition that often offers their products for cheaper up front?
But self hosting is non-trivial. You have to deal with DNS, TLS certificates, configuring Keycloak, data backups, and redundancy.
I set it up once so I could evaluate it. I may yet choose to self host but I'm not under any illusions that it's easier than paying for a service.
