swap Photoprism with Immich. Its a lot better imo
I would like to hear a bit more about the main differences. I tried immich first on a resource constrained system and it was a real pig naturally. PhotoPrism seems to be less resource intensive, but my new AMD Ryzen 7 mini pc is also a lot more powerful than a pi 4.
Im willing to go either way and this one will probably be near the bottom of the list anyway, so I have time to learn more and perhaps change my mind.
Regarding mini PCs; Beware of RAM overheating!
I bought some Minisforum HM90 for Proxmox selfhosting, installed 64gb RAM (2x32gb DDR4 3200MHz sticks), ran memtest first to ensure the RAM was good, and all 3 mini PCs failed to various degrees.
The “best” would run for a couple of days and tens of passes before throwing multiple errors (tens of errors) then run for another few days without errors.
Turns out the RAM overheated. 85-95 C surface temperature. (There’s almost no space or openings for air circulation on that side of the PC). Taking the lid off the PC, let 2/3 computers run memtest for a week with no errors, but one still gave the occasional error bursts. RAM surface temperature with the lid off was still 80-85 C.
Adding a small fan creating a small draft dropped the temperature to 55-60 C. I then left the computer running memtest for a few weeks while I was away, then another few weeks while busy with other stuff. It has now been 6 weeks of continuous memtest, so I’m fairly confident in the integrity of the RAM, as long as they’re cold.
Turns out also some, but not all, RAM sticks have onboard temperature sensors. lm-sensors can read the RAM temperature, if the sticks have the sensor. So I’m making a Arduino solution to monitor the temperature with a IR sensor and also control an extra fan.
Thanks for the tip on measuring temp of the ram, too. I will incorporate that into my monitoring scheme.
The mini pc I have has a good case design with a fan that blows across the ram, cpu and ssd. So I think it has good cooling, but I will definitely confirm with some monitoring.
Nice, my HM90s have a really great cooling solution for the CPU (big silent fan, fine finned heat sink). But no cooling on the bottom side of the main board, which houses the RAM, a NVMe and two 2,5" SATA SSDs.
As usual, the arch wiki is super helpful also for non-arch distros wiki.archlinux.org/title/Lm_sensors#Adding_DIMM_t…
Photoprism is less “resource intensive” because it’s offloading face detection to a cloud service. There are also many who don’t like the arbitrary nature of which features photoprism paywalls behind its premium version.
If you can get past immich’s initial face recognition and metadata extraction jobs, it’s a much more polished experience, but more importantly it aligns with your goal of getting out of the cloud.
The main difference i would say is the development and licensing model. Photo prism is forcing ppl who want to commit to sign a CLA to.give away their rights. Also the community is not really active it is mainly one dev that can change the code license on any given time.
Immich does not have such an agreement and has a huge active contributor community around it. Also Immich is backed by Futo which has its pros and cons.
Imho the biggest pain in self hosting is when a foss product turns evil towards its community and start to practice anti consumer/free selfhosters business practices.
Immich is far less likely to turn evil.
Good insights, thank you for the perspective. I will look into that more closely before committing.

Are both immich and photoprism container-dependent, or just immich?
(If they fail 27002, they’re a hard no for me).
