I appreciated his comparison charts for various alternatives and the features they offered. I’m going to check out Ente and Stingle for self-hosted photo backup.
Ente is great if you need a drop-in Google Photos replacement that is open-source, E2EE, externally audited and private. It’s the perfect solution for families tbh. Switched to it like two weeks ago and it’s been great so far.
Ente is as close as you can get to Google Photos with E2EE right now. I recently migrated there. The migration wasn't painless and involved some scripting to handle albums and duplicates but the service itself is really good. Can recommend!
