Auth apps

What auth apps do you use ive seen authelia, authentik, keycloack but whats overall the best

Its really stange seeing kanidm basically never mentioned in these types of threads dispite how perfect it is for selfhosting: great documentation, incredibly easy to get setup, easy to make a custom themed/setup auth page, lets users name themselves how they prefer instead of requiring “firstname lastname” (why does every service need a lastname when it never gets used?)

Authelia and authentik are cool but are way more complex then you need for authenticating a couple services and for me at least feel “bloated” for my usecase
