Two different goals
Noodle Gallery and PhotoPrism are both open-source, self-hosted photo apps — but they were built to solve different problems.
Noodle Gallery is designed around the automatic-backup workflow: your phone backs up silently in the background, photos land in a shared family timeline, and the experience is close to Google Photos. It is built on top of Immich and adds Shared Spaces, Global People, native mobile apps, and other features on top of that foundation.
PhotoPrism is designed around browsing and organizing an existing collection. It emphasizes AI-powered labels, a rich search interface, and a clean library view. It does not ship a first-party native mobile app for automatic backup.
Neither is universally "better" — they optimize for different workflows. This page lays out the differences honestly so you can pick the one that fits your situation.
Side-by-side comparison
| Dimension | Noodle Gallery | PhotoPrism |
|---|---|---|
| Primary goal | Private Google-Photos replacement: auto-backup + timeline | Library browser & AI organizer for an existing collection |
| Native mobile apps | iOS + Android with automatic background backup | Progressive web app; no first-party native backup app |
| Shared libraries & users | Multiple accounts, Shared Spaces, member roles | Multi-user available, with fewer sharing controls |
| AI / search | CLIP smart search, face & object recognition | TensorFlow labels, faces, and search |
| Storage backends | Local disk or any S3-compatible provider | Local disk (object storage via external mounts) |
| License & cost | AGPL-3.0, free to self-host | AGPL-3.0; some features behind Membership |
| Upstream | Built on Immich, rebased onto every release | Independent project |
When to choose Noodle Gallery
Gallery is likely the right fit if you want:
- Automatic phone backup running silently in the background
- A native iOS or Android app — not a web app pinned to your home screen
- A shared family timeline where multiple people's photos live together
- A Google Photos-style experience with a timeline and Memories
- S3-compatible storage (AWS S3, Cloudflare R2, MinIO, Backblaze B2)
When to choose PhotoPrism
PhotoPrism may be a better fit if you want:
- A powerful browser for an existing, already-organized photo collection
- TensorFlow-based subject labels and AI classification without the backup focus
- A lightweight, single-user setup with no mobile backup requirement
- A project with a longer independent track record
Switching from PhotoPrism to Gallery
PhotoPrism and Noodle Gallery use different storage layouts and database schemas, so switching is not a simple image-name swap. Your original photo files are never modified by either app — both read from and write to a directory of files — so a fresh import into Gallery is safe.
The typical path is to point Gallery at the same directory your PhotoPrism library uses (or copy it) and let Gallery index it fresh. You will lose PhotoPrism-specific metadata (tags, labels, albums) that has no equivalent in Gallery's schema, but your original photos and videos are always preserved.
Frequently asked questions
Can I migrate my PhotoPrism library to Noodle Gallery?
Not as a drop-in swap. PhotoPrism and Noodle Gallery use different database schemas and storage layouts, so there is no two-line migration. To switch, you would import your photo files fresh into Gallery — your original files are never deleted or modified by either app, so a fresh import is safe and low-risk. You point Gallery at your photo and video files and let it index them directly — there's no special import wizard needed, and your originals are never modified.
Which should I pick — Noodle Gallery or PhotoPrism?
It depends on your primary use case. If you want automatic phone backup, native iOS and Android apps, shared family timelines, and a Google Photos-style experience, Gallery is built for that. If you already have a large organized photo collection and want a powerful browser and AI classifier without the backup focus, PhotoPrism is well-suited. Both are high-quality open-source projects; the right choice is the one that matches what you actually need.
Does Noodle Gallery have a mobile app?
Yes. Noodle Gallery is live on both the App Store (iPhone) and Google Play (Android) with background camera backup, on-device CLIP search, the map view, and Shared Spaces. Automatic background backup is one of Gallery's core features.
Is PhotoPrism free?
PhotoPrism is open-source under AGPL-3.0, and the community edition is free to self-host. Some advanced features are available to members who support the project. Noodle Gallery is also AGPL-3.0 and free to self-host with all features included.
