Translating

Create a collaboration session manually

In order to create a session manually, you just need to generate a link of this form:

https://excalidraw.com/#room=[0-9a-f]{20},[a-zA-Z0-9_-]{22}

Example

https://excalidraw.com/#room=91bd46ae3aa84dff9d20,pfLqgEoY1c2ioq8LmGwsFA

The first set of digits is the room. This is visible from the server that’s going to dispatch messages to everyone that knows this number.

The second set of digits is the encryption key. The Excalidraw server doesn’t know about it. This is what all the participants use to encrypt/decrypt the messages.

Note: Please ensure that the encryption key is 22 characters long.

docker-compose up --build -d

Self-hosting

We publish a Docker image with the Excalidraw client at excalidraw/excalidraw. You can use it to self-host your own client under your own domain, on Kubernetes, AWS ECS, etc.

docker build -t excalidraw/excalidraw .
docker run --rm -dit --name excalidraw -p 5000:80 excalidraw/excalidraw:latest

The Docker image is free of analytics and other tracking libraries.

At the moment, self-hosting your own instance doesn't support sharing or collaboration features.

We are working towards providing a full-fledged solution for self-hosting your own Excalidraw.
