Free. No credit card. Sign in only when you want to save.
Built for diagrams you want to keep
The Excalidraw canvas you already know, with the parts that stop sketches from getting lost.
Organize
Everything in its place
Group diagrams into workspaces and nested folders, then drag any diagram where it belongs.
Versions
Every version, saved
Save named checkpoints, preview any past version, and restore it in one click.
Private
Encrypted before it leaves your browser
Diagrams you draw in the browser are locked with their own key before they are saved. CanvasKeep only stores the locked version, so what sits on the server is ciphertext, not your diagram.
Any device
Same diagrams on a new browser
Set a passphrase and keep a recovery key. On a new device your passphrase unlocks your key. CanvasKeep keeps a locked backup that it cannot open.
AI
Let your AI draw it
The CanvasKeep MCP server lets Claude, Codex, or any MCP client create diagrams straight in your workspace.
