If you use Nextcloud, install the App Memories and you will have the same functions as Immich plus all the upload functions of Nextcloud.

But if you are not interested in all the Nextcloud functionalities (including contact and calendar sync, musicserver, filesharing, etc) and just want picture management, Immich is the better choice.

Gnome devs threatening me with a good time on my surface laptop. Please stop.

Totally different for me:

• NC-calendar syncs two different calendars (work and private) accross all my devices.
• NC Photos with Memories organizes 2 TB of photos and has all the functions Immich has.
• NC Password Manager syncs my Passwords
• I share big files with my clients via NC and photo albums to friends and family.
• NC syncs and organizes different Input-folders for my paperless-ngx-server.
• I update NC with a small script, works every time

So it replaces at least 5 different Programs. And it’s 80 % private use, 20 % for my business. Not too big, not too clunky, just the right tool.
