The truly wild thing about subscription pricing to me is how viscerally I'm against it. I'm not shitting on this business model, I think it makes perfect sense and is probably the only logical way to run a business like this. I'm just saying that everything in our lives is trying so hard to turn everything into a recurring fee that my first reaction to every recurring fee is pure hatred.
Alright, so the amount of data I'd need for pictures is probably the 500GB tier, so $9.99/mo. My first thought is that's way too expensive, my second thought is that I'm not doing another subscription. My subscription-trauma addled brain will happily justify buying a little server, and a 1TB hard drive, and spending hours configuring them. By the time I'm done, I'll have spent the equivalent of at least 3 years of the cost of this service, plus tons of my free time, and it will never work exactly right because there's always going to need to be updates, and sometimes those will break something, and I'll need to fix it myself.
Anyway, it looks cool though.
I use Photoprism. It is sufficient, amazing even for what it is, but there's a definite curve to getting it set up properly and there's some babysitting involved to make sure everything keeps working.
