Open-source alternatives to Excalidraw+ (self-hosted, 2026)
Excaliself, ExcaliDash, Nextcloud Whiteboard, and plain self-hosted Excalidraw compared with Excalidraw+ on accounts, SSO, collab, comments, history, and AI.
Excaliself vs ExcaliDash
Two self-hosted Excalidraw apps with accounts and live collab. ExcaliDash leads on version history and view-only links; Excaliself on Team space, SSO, and MCP.
Excaliself vs Nextcloud Whiteboard
Nextcloud Whiteboard and Excaliself both put the Excalidraw editor on your server. If you already run Nextcloud, the answer is easy. If not, see the trade-offs.
How to self-host Excalidraw (with collaboration that stays on your server)
Run the official Excalidraw Docker image, see why live collaboration still calls excalidraw.com, and get self-hosted Excalidraw with collab on your own server.
