TL;DR #

Immich is a high-performance self-hosted photo and video backup solution that has become the de facto Google Photos alternative for privacy-conscious users. With 106,557 GitHub stars, it is one of the most popular self-hosted applications on the entire platform.

Key strengths:

• Full-featured mobile app (Flutter) with automatic background backup
• Web interface with album management, timeline view, and map view
• AI-powered face recognition, object detection, and scene analysis
• Multi-user support with granular permissions
• Active development with 300+ contributors and weekly releases

What Is Immich? #

Immich is an open-source, self-hosted backup solution for your photos and videos. It provides a Google Photos-like experience while keeping all your data on your own hardware. The project was initiated by Alex Tran in 2021 and has grown into one of the largest self-hosted projects on GitHub.

The architecture consists of:

• Mobile apps (iOS/Android) built with Flutter for seamless backup
• Web app built with Angular for desktop management
• Backend API built with NestJS and TypeScript
• Database using PostgreSQL for metadata and MinIO/S3 for file storage
• Machine learning pipeline for face recognition and object detection

# Quick start with Docker Compose
docker compose up -d

# Verify installation
curl -s http://localhost:2283/api/server-info | jq

Why It Matters #

Privacy-First Design #

In an era where tech giants monetize your personal photos, Immich offers a compelling alternative. All your media stays on your infrastructure — no cloud uploads, no data mining, no algorithmic manipulation of your feed.

Massive Community Adoption #

With 106K+ stars and 6K+ forks, Immich has one of the most active communities in the self-hosted space. The project receives regular updates, has extensive documentation, and integrates seamlessly with popular self-hosted ecosystems like Nextcloud and Synology NAS.

AI-Powered Features #

Unlike basic photo managers, Immich includes sophisticated AI features:

• Face Recognition: Automatically detects and groups faces across your entire library
• Object Detection: Identifies objects, scenes, and activities in your photos
• Semantic Search: Search your photos using natural language (“cat on the beach”)
• Timeline View: Organize photos by date, location, and people

Architecture Deep Dive #

Backend Stack #

Immich uses a modern, modular architecture:

// Core API structure
class MediaRepository {
  async upload(userId: string, file: Buffer): Promise<MediaEntity>
  async findByOwner(ownerId: string, page: number): Promise<MediaEntity[]>
  async deleteOrphanedAssets(): Promise<number>
}

class AssetService {
  async processAsset(asset: MediaEntity): Promise<void> {
    await this.faceRecognition.process(asset);
    await this.objectDetection.process(asset);
    await this.thumbnailGeneration.process(asset);
  }
}

The NestJS backend provides:

• RESTful API with OpenAPI documentation
• WebSocket support for real-time updates
• Background job processing with BullMQ
• File upload handling with multer

Frontend Architecture #

The Flutter mobile app provides native performance on both iOS and Android:

• Automatic background backup with configurable WiFi/cellular settings
• Offline-first design with local SQLite cache
• Smooth scrolling and image loading with progressive JPEG support
• Widget support for home screen quick access

Storage Strategy #

Immich supports multiple storage backends:

• Local storage: Direct filesystem access for simple deployments
• MinIO/S3: Object storage for scalable, distributed setups
• External drives: Mount-based storage for NAS deployments

# docker-compose.yml storage configuration
services:
  immich-server:
    volumes:
      - /path/to/photos:/mnt/photos
      - /path/thumbs:/tmp/thumbs
  immich-machine-learning:
    volumes:
      - /path/models:/cache

FAQ #

Advanced Configuration #

Custom ML Models #

Immich supports custom machine learning models for face recognition and object detection:

# Upload a custom face recognition model
curl -X POST http://localhost:2283/api/machine-learning/models/upload   -H "Authorization: Bearer YOUR_TOKEN"   -F "model=@custom-face-model.onnx"

# Set as default
curl -X PUT http://localhost:2283/api/config/machine-learning/model   -H "Authorization: Bearer YOUR_TOKEN"   -d '{"model": "custom-face-model"}'

Backup Strategies #

Configure intelligent backup policies to optimize storage and bandwidth:

# Backup configuration
backup:
  # Only backup on WiFi
  network_policy: wifi_only
  
  # Original quality vs compressed
  quality: original
  
  # Backup specific albums only
  selective_backup:
    enabled: true
    albums: ["Family", "Travel", "Pets"]
    
  # Schedule backups
  schedule:
    daily: "02:00"
    weekly_full: "sunday 03:00"

Reverse Proxy Setup #

For production deployments, configure a reverse proxy:

server {
    listen 443 ssl http2;
    server_name photos.yourdomain.com;

    ssl_certificate /etc/letsencrypt/live/photos.yourdomain.com/fullchain.pem;
    ssl_certificate_key /etc/letsencrypt/live/photos.yourdomain.com/privkey.pem;

    location / {
        proxy_pass http://localhost:2283;
        proxy_set_header Host $host;
        proxy_set_header X-Real-IP $remote_addr;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        proxy_set_header X-Forwarded-Proto $scheme;
        
        # WebSocket support for live sync
        proxy_http_version 1.1;
        proxy_set_header Upgrade $http_upgrade;
        proxy_set_header Connection "upgrade";
    }
}

Performance Tuning #

For large libraries (100K+ photos), optimize performance:

# Increase database connection pool
export DB_POOL_SIZE=20

# Enable Redis caching
export REDIS_URL=redis://localhost:6379

# Adjust thumbnail generation
export THUMB_SIZE_SMALL=256
export THUMB_SIZE_MEDIUM=1024
export THUMB_SIZE_LARGE=2048

Shared Albums and Collaboration #

Immich supports collaborative album management:

# Create a shared album
curl -X POST http://localhost:2283/api/albums   -H "Authorization: Bearer YOUR_TOKEN"   -d '{"title": "Summer Vacation", "sharedWith": ["user1@example.com"]}'

# Add photos to shared album
curl -X POST http://localhost:2283/api/albums/abc123/assets   -H "Authorization: Bearer YOUR_TOKEN"   -d '{"assetIds": ["asset1", "asset2", "asset3"]}'

Q: Can Immich replace Google Photos completely? #

A: Yes, for most users. Immich offers automatic backup, face recognition, search, and sharing — all the core Google Photos features, but self-hosted.

Q: How much storage do I need? #
