I use it and it works great for me. My use case is I have several users which backup our mobile phones into Immich. Then I created an additional “user” that is more like a service account. Under this extra account I have it set to scan an external path which I a drive where we upload everything from a DSLR camera. Then I share this users library with my main account so I can browse our DSLR images while on the go through Immich.

I use Brevo.com which gives a generous 300 emails per day limit on the free plan.

I will say that the web portal is a bit confusing but once you set it up you basically never need to go there again.

Take a look at Mattermost as well. https://github.com/mattermost/mattermost

I agree with you but also about 90% of watching on my instance happens on smart TV’s. So even though I would like to have oidc supported for the occasional phone/pc user I would still need something basic that a TV can use.
