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.
