I unironically have been making a text file of photo management tools I wanted to go through and try before picking one to settle on. Thank you for this comparison chart!

Edit, the text file contents so far:

• Damselfly • Immich • Lychee • Media Goblin • Photo-Stream • Photoprism • Photoshow • Photostructure • Photoview • PiGallery2 • Piwigo • Pixapop • Photobox
