CanvasKeep

Made by@canvaskeep avatar@canvaskeep
CanvasKeep is a free diagramming tool built on the Excalidraw canvas. Excalidraw is great for quick sketches but has nowhere to keep them, so I added the missing layer: workspaces, nested folders, and named version history you can preview and restore in one click. Diagrams are encrypted in the browser (AES-GCM) before they are saved, and you can share a view-only link that carries its key in the link. There is also an MCP server so Claude or other AI clients can create diagrams straight into your workspace. You can start drawing with no account.
