FAQ

Common questions

Do I need an account to use Modudraft?

No. You can use the full canvas and MCP server without signing up. Everything saves to your browser's local storage. Create an account to sync diagrams across devices.

What does "local only" mean for the Free plan?

Your diagrams are stored in your browser's localStorage — they persist across sessions on the same device, but won't sync to other devices or survive clearing browser data. Export a .modudraft file to back them up.

Can I self-host Modudraft?

Not yet. If self-hosting is important for your team, reach out — it's on the roadmap.

How does the MCP server work?

The Modudraft MCP server lets Claude, Cursor, or any MCP client read and modify your canvas. Read the MCP docs for setup instructions.
