CanvasKeep
Save, organize, and restore every diagram you draw
CanvasKeep is a web diagramming tool built on the Excalidraw canvas. It adds saved projects, nested folders, and named version history, so your flowcharts, wireframes, and mind maps stay organized and any earlier version is one click away. Sketching a diagram is the easy part — keeping track of it is the hard part. CanvasKeep gives every diagram a home with workspaces and nested folders so related designs stay together as your library grows. It is free, runs entirely in the browser, and needs no setup.
