Dupe Zappa vs Immich
Immich is a self-hosted photo server for mobile backup, partner sharing, and ML face search in a Google Photos-like web app. Dupe Zappa Face Recognition runs on your Windows PC against existing folder trees with local ONNX models. Pick the tool that matches where your photos actually live.
Why Dupe Zappa
Clean up the library sync servers cannot
Immich backs up phones. Dupe Zappa cleans up what lands on disk.
Dedup on any folder
Immich's Duplicates Utility stays inside its library; Dupe Zappa scans wherever your files live.
One-time price, local-first
No server hardware or hosting costs for face and cleanup workflows.
Verdict
Who should pick what
Keep Immich if
Keep Immich if your primary problem is backing up phone camera rolls to your own server, sharing with a partner, and browsing everything in one household gallery.
Add Dupe Zappa if
Add Dupe Zappa when photos already live on Windows drives and NAS paths, you need faces without a sync server, and you want people discovery tied to duplicate cleanup and Universal Search.
Replace entirely?
Replace Immich entirely only if you never rely on mobile auto-backup or the household web gallery. Dupe Zappa does not upload phones or host a shared photo server.
Complementary
Phone backup and desktop cleanup differ
A sync server and a folder-native toolkit solve different photo problems. Run one, the other, or both depending on where files live.
01
Phone-first library
Use Immich when cameras on phones are the source of truth and you want automatic backup to your server.
02
Desktop folder cleanup
Use Dupe Zappa when archives, exports, and NAS copies need face grouping, dedup, and search without moving files into a server library.
Folder problems
Where Dupe Zappa wins on scope
Immich organizes a server library; these jobs stay on your folders.
| Need | Immich | Dupe Zappa |
|---|---|---|
| Face groups on messy Windows/NAS folders | Requires server library | Local ONNX on existing paths |
| Delete duplicates outside the app library | Duplicates Utility is library-scoped | Duplicate Scanner on any folder |
| Dedup burst shots after naming a person | Manual selection in the utility | Face tags + Duplicate Scanner + undo |
