End-to-End-Encrypted Self-Hosted Photo Backup With Immich-Quality Mobile Daily-Backup UX
The two leaders in self-hosted photo backup split the market wrong... Immich has the polished mobile app and ML face/object search, but stores files unencrypted on the server. Ente has zero-knowledge E2E encryption, but the self-hosted variant is rough and the ML features depend on Ente's infra. Self-hosters want both: 'I want my server compromised and the attacker still can't see my kids' photos, AND I want the daily-backup UX of Immich.' This is the loudest unmet ask in 2026 photo-backup discussions.
The non-obvious play is client-side indexing + encrypted index sync to server, so search 'just works' across devices without the server ever seeing pixels. Trying to do server-side ML on encrypted data is a research project. Don't compete on ML quality, compete on 'your photos cannot be exfiltrated even if I'm pwned.'

It is a true polarity: encryption OR mobile UX, never both. Server-side ML on encrypted blobs is hard but no longer impossible (homomorphic search, client-side index sync). No project is shipping it.
