🛠️ How to Self-Host Excalidraw (With Docker)
For privacy-conscious users or organizations, running your own instance of Excalidraw is a great choice.
Here’s how to do it using Docker:
✅ Prerequisites
- A server or local machine with Docker installed.
- Terminal access.
- Internet connection to pull the Docker image.
🚀 Step-by-Step Tutorial
Step 1: Pull the Excalidraw image
docker pull excalidraw/excalidraw
Step 2: Run the Docker container
docker run --rm -dit --name excalidraw -p 5000:80 excalidraw/excalidraw:latest
This exposes Excalidraw on port 5000. You can visit it in your browser:
http://localhost:5000
Or if you’re deploying to a server:
http://your-server-ip:5000
🎉 That’s it! You now have your own private Excalidraw whiteboard.
🧩 Bonus: Enable Collaboration in Your Self-Hosted Instance
By default, collaboration is not enabled in the Docker version. But you can add it using the Excalidraw Room Server (WebSocket server for real-time sync).
You’ll need to:
- Clone the collaboration server repository.
- Run the server (Node.js required).
- Point your self-hosted Excalidraw client to use that WebSocket server.
This gives you full control over shared drawing sessions without sending any data to external servers.
