A lightning-fast, minimalist web frontend for the Czkawka duplicate file finder.

I built this because I wanted to run Czkawka on my server, but I needed a good UI and easy Docker deployment for it.

Image swipe comparison mode:

• All Czkawka scans: Supports every scan type that Czkawka offers.
• Image comparisons: Side-by-side, swipe, and onion skin comparison modes.
• Fullscreen preview: View images and videos in fullscreen mode.
• Keyboard navigation: Navigate through files using arrow keys and mark duplicates with space.
• Docker deployment: Easy deployment on headless servers via Docker.

Pull the pre-built image from GitHub Container Registry:

docker pull ghcr.io/jackra1n/czkawka-web

docker run -d \
  --name czkawka-web \
  -p 6198:6198 \
  -v czkawka-web-data:/data \
  -v /path/to/your/files:/mnt/files \
  ghcr.io/jackra1n/czkawka-web

services:
  czkawka-web:
    image: ghcr.io/jackra1n/czkawka-web
    container_name: czkawka-web
    ports:
      - "6198:6198"
    volumes:
      - ./data:/data
      # Mount directories you want to scan:
      # - /path/on/host/to/files:/mnt/files
    restart: unless-stopped

Then start it:

docker compose up -d

This project is built with an emphasis on zero bloat and high performance.

• Backend: Rust + Axum
• Frontend: SvelteKit
• Bun
• Mise

If you want to build the image locally from source instead of using the pre-built one, use the development compose file:

cp .env.example .env
# Edit .env and set SCAN_PATH to the directory you want to scan
mkdir -p data
docker compose -f compose.dev.yaml up

If you use Mise, you can also run:

mise run docker

A huge thanks to qarmin for creating and maintaining czkawka. This project wouldn't be possible without the incredible work put into that amazing project.
