Excalidraw is an open-source virtual whiteboard for sketching hand-drawn-style diagrams. It is local-first: your drawings live privately in your own browser, with no account, login or password to manage. This cloudimg image self-hosts BOTH halves of Excalidraw - the static web app served by nginx on port 80 and the official excalidraw-room collaboration server on loopback - so you get a fully private, on-prem deployment with no dependency on the public excalidraw.com. Backed by 24/7 expert support.
Fully Private, On-Prem
The static SPA is built from the official source and served from /var/www/excalidraw; the official excalidraw-room collaboration server runs on loopback 127.0.0.1:3002, never publicly exposed. Your whiteboard data never leaves your host.
Real-Time Collaboration
Click Share then Live collaboration to start a session and share a room link served by this VM's own room server - nginx reverse-proxies the Socket.IO path with WebSocket upgrade headers so collaboration connects to your own VM, not a public server.
