wklejka

Lightweight, browser-based shared clipboard. Paste text, images or files on one computer and instantly pick them up on another. Real-time sync via WebSocket, no sign-up required.

Getting started

1. Make sure Docker is installed.
2. Create a docker-compose.yml file:

services:
  wklejka:
    image: ghcr.io/krbob/wklejka:latest
    ports:
      - "3000:3000"
    volumes:
      - ./data:/app/data
    restart: unless-stopped

3. Start the service: docker compose up -d.
4. Open http://localhost:3000 in a browser (from another machine: http://<IP>:3000).

Alternatively, run the container directly:

docker run --rm -p 3000:3000 -v ./data:/app/data ghcr.io/krbob/wklejka:latest

Features

• Text, images & files – paste (Ctrl+V), drag and drop, or use the file picker. Any file type up to 50 MB. Inline preview for PDFs, videos, and audio.
• Real-time sync – WebSocket instantly propagates changes to every open browser.
• Tabs – separate virtual documents (e.g. "Work", "Home") with optional auto-expiry (1 h, 24 h, 7 d, 30 d). Drag to reorder, double-click to rename.
• Tab locking – lock a tab to prevent accidental deletion of the tab or its clips. Unlocking requires typing the tab name (like deleting a GitHub repo).
• Copy / Download / Delete – on every entry. Delete requires inline confirmation.
• Link previews – URLs in text clips automatically show a preview card with title, description, and image.
• Dark mode – auto-detects system preference, manual toggle in header. Persisted across sessions.
• Persistent storage – data lives in the data/ directory and survives container restarts.
• Startup orphan cleanup – unreferenced files in data/files and data/images are removed when the app starts.
• Multilingual – UI automatically switches between Polish and English based on browser language.

UI language

Language is detected automatically from navigator.language. You can override it with a URL parameter:

• http://localhost:3000?lang=pl – Polish
• http://localhost:3000?lang=en – English
