The project as a whole feels competent.
Stuff that should be fast is fast. E.g. upload a few tens of thousands of photos (saturates my wifi just fine), wait for indexing and thumbnailing to finish, and then jump a few years in the scroll bar - odds are very good that it'll have the thumbnails fully rendered in like a quarter of a second, and fuzzy ones practically instantly. It's transparently fast.
And the image folder structure is very nearly your full data, with metadata files along side the images, so 99% backups and "immich is gone, now what" failure modes are quite easy. And if you change the organization, it'll restructure the whole folder for you to match the new setup, quietly and correctly.
Image content searching is not perfect (is it ever?), but I can turn it on in a couple clicks, search for the breed of my dog, and get hundreds of correct matches before the first mistake. That's more than good enough to be useful, and dramatically better than anything self-hosted that I've tried before, and didn't take an hour of reading to enable.
It's "this is like actually decent" levels that I haven't seen much in self-hosted stuff. Usually it's kinda janky but still technically functional in some core areas, or abysmally slow and weird like nextcloud, but nope. Just solid all around. Highly recommended.
I logged in for the first time in months a few days ago and it was mostly angry memes, a surprising number of which were celebrating violence and murder. This is despite me aggressively muting people who post that sort of thing.
I hope they find a niche, but the cultural damage may already be done.
I am always annoyed using it, how bad it is these days. Then I try the alternatives such as Duck Duck Go and they manage to be even worse.
Qwant is semi-ok but it also omits tons of things that Google Search finds (and also is slower, for some weird reason).
Google's UI nerf is also annoying - so much useless stuff. In the past I could disable that via ublock origin but Google killed that for chrome.
We need to do something against this Evil that Google brought into this world.
