In order to give Ente a try I self hosted it. It's working great. The initial interest was also E2E encryption.

The backing Minio store is on a VPS to keep it off-prem. The rest (front end UI etc) I host in my home and use the same VPS as a reverse proxy.

Right now I don't share with anyone else, but use it to get photos sync'd off my phone and shared with my own desktop/tablets.

I'm sticking with it and my family is interested in using as part of degoogle'ing. So I eventually will pay for it for a way to better share photo albums (i.e. too many photos to just share over Signal).
