Immich - Started recently due to Google Photos changes, lots of praise and fast development but consider chances of becoming abandonware if dev loses interest?
Lychee - Doesn't look like it does what I want, UI is barebones
LibrePhotos - Another recently started project, also with fast development. UI is unpolished.
PhotoPrism - AI classification. Has been going for a while, seems pretty active.
PhotoStructure - Think this is pretty recent but the dev's goal was that it does not touch your existing file structure (which is a big plus)
