Well, not E2EE, but I like Photoprism very much for the self-hosted photosharing use-case. In fact, I tried Ente a while ago and am always impressed by their communication skills, but from a product side, I prefer Photoprism.

I have a local instance running on a Raspberry Pi with about 149.000 photos inside.

I said E2EE because that's a significant constraint and open servers is another constraint.

Matrix?

https://actualbudget.org is fantastic and self-hostable, but or can be installed locally on a desktop. There's no cloud version but it still largely fits your criteria.

Immich. It's very feature rich and has a massive community.

Not end to end encrypted. I wouldn't want anyone else to use my hosted version without end to end encryption.

What do you like about AGPL in this context? Building a similar product and curious! Thanks

I don't like copyright at all and I don't like the FSF but it protects the users freedoms which gives the community trust. With AI I think any copyright will be less and less important, though.

not e2ee but you can use immich behind pangolin/reverse proxy
