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.

1. Make sure Docker is installed.
2. Run the container: docker run --rm -p 3000:3000 -v ./data:/app/data ghcr.io/krbob/wklejka:latest.
3. Open http://localhost:3000 in a browser (from another machine: http://<IP>:3000).

Alternatively with docker compose:

git clone https://github.com/krbob/wklejka.git
cd wklejka
docker compose up -d

• 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).
• Copy / Download / Delete – on every entry.
• Persistent storage – data lives in the data/ directory and survives container restarts.
• Multilingual – UI automatically switches between Polish and English based on browser 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
