Deep Dive: Switching from Excalidraw+ to WBO
Trade-offs, installation & data architecture
What you trade away
WBO lacks Excalidraw's polished drawing tools, reusable libraries, file organization, export quality, and managed team workspace.
How to deploy WBO
Use the free hosted instance, or run the Docker image/Node.js server
What it takes to run
None for the public instance; self-hosting needs Docker or Node.js, a persistent writable volume with the expected user ownership, backups, and a public URL/TLS
Where your data lives
Boards are persisted as JSON files in the server's data directory; a Docker deployment must mount that directory, while public-hosted boards live on the operator's server
Why fork WBO instead of vibe-coding a Excalidraw+ clone?
Excalidraw+'s solo core is compact: build a browser-based collaborative whiteboard editor with drag, resize, connect, keyboard shortcuts, autosave, and SVG or PNG export. A competent builder can reach a useful personal version in one sitting, while the paid product mainly wins on interaction polish, collaboration.
