Immich and PhotoPrism are the two serious answers to self-hosted photo management in 2026, and they started from opposite ends of the problem. Immich set out to clone Google Photos: phone in pocket, photos appear on your server. PhotoPrism set out to be a smart index on top of the photo archive you already own.
They have grown toward each other, but the DNA still shows in daily use - and in the VPS bill.
TL;DR: Which One Should You Pick?
Pick Immich if the job is replacing Google Photos for your household: automatic mobile backup, face recognition, shared albums, and a timeline that just works. Budget 8 GB RAM.
Pick PhotoPrism if you have a large existing archive in folders you want indexed in place, prefer a single lighter service, and care more about curation than phone sync.
Immich vs PhotoPrism at a Glance
| Immich | PhotoPrism | |
|---|---|---|
| Core model | Mobile-first backup (Google Photos clone) | Index existing library in place |
| Mobile apps | First-class iOS/Android with auto-upload | PWA + third-party clients |
| Face recognition | Yes, strong | Yes, decent |
| Smart search | CLIP natural-language search | Classification labels |
| Stack | Node.js + Postgres + Redis + ML container | Go binary + MariaDB |
| Realistic RAM | 4 GB min, 8 GB comfortable | 2-4 GB |
| Multi-user | Yes, partner/family accounts | Yes (single admin focus) |
| Development pace | Very fast, frequent releases | Steady |
Where Immich Wins
The phone-to-server pipeline. The mobile apps are the best in self-hosted photography by a wide margin: background auto-upload, deduplication, album sharing with a partner, and a timeline indistinguishable from the commercial product it clones. Search by “red car at the beach” works. For a family that wants to leave Google without losing convenience, Immich is the only complete answer.
The cost is a heavier stack - Postgres, Redis, and a machine-learning sidecar - and a project that moves so fast you should read release notes before updating. Our best VPS for Immich guide has the sizing details.
Where PhotoPrism Wins
Respect for your archive. PhotoPrism indexes originals where they live, never rewrites your folder structure, and packs everything into one Go binary plus MariaDB. It is noticeably lighter at idle, and its curation tools - review flags, quality filters, private markers, powerful search filters - suit photographers triaging decades of shots rather than families syncing phones.
Mobile capture is the weak spot: the PWA works, but there is no polished first-party auto-upload experience like Immich’s.
VPS Requirements Compared
| Spec | Immich | PhotoPrism |
|---|---|---|
| Minimum RAM | 4 GB | 2 GB |
| Recommended RAM | 8 GB | 4 GB |
| Storage | 50 GB min, grows with library | Same, indexes in place |
| CPU | High during ML jobs | High during initial indexing |
| Database | Postgres | MariaDB |
Photo libraries grow relentlessly, so storage per euro dominates the provider choice. Contabo from 5.99 EUR per month offers the largest NVMe disks per euro and is the budget pick for either app. Hetzner from 5.49 EUR is the quality pick - fast NVMe for thumbnail generation and cheap expansion volumes when the library outgrows the disk. US households closer to DigitalOcean regions (from 6 USD) get snappier mobile uploads.

Verdict
Immich is the Google Photos replacement; PhotoPrism is the archive librarian. Households replacing a cloud subscription should default to Immich and size the VPS at 8 GB. Photographers with a curated folder tree and no need for phone sync will be happier with PhotoPrism on half the hardware.
A pattern we see on r/selfhosted and endorse: some users run both against the same external library - Immich for the family’s phones, PhotoPrism for the archival deep-cuts. On a 16 GB Contabo plan, that combination still costs less per month than the cloud storage it replaces.
Frequently asked questions
Which needs a bigger VPS, Immich or PhotoPrism?
Immich. Its machine-learning container for face recognition and smart search wants RAM of its own, which is why 4 GB is the realistic minimum and 8 GB is comfortable for family libraries. PhotoPrism runs its TensorFlow classification in a single process and manages fine on 2 to 4 GB if you let the initial indexing take its time.
Can Immich and PhotoPrism import an existing photo folder structure?
Both can, but PhotoPrism is built around it: point it at your originals folder and it indexes in place without moving files. Immich added external library support and it works, but the app is happiest managing uploads from its mobile apps into its own storage layout. If your archive is a carefully organized folder tree you want kept intact, PhotoPrism respects that model more naturally.
Does either app match Google Photos search quality?
Immich comes closest. Its CLIP-based smart search finds photos by natural language surprisingly well, and face recognition groups people reliably after training on a few hundred photos. PhotoPrism's classification is solid for scenes, colors, and locations but feels a generation older for freeform queries. Neither fully matches Google, but Immich narrows the gap every release.
