I can only support that. This is what I am running for my small business as well and it’s been super smooth for roughly a year now! Especially self service and auto-registering based on domain names turned out to be really nice features (for a business). In my homelab I just enjoy having a nice ui.

I came from Authentik which was nice too but nowhere as feature rich as zitadel.
