Your diagrams stay in this browser

This is an early alpha. Nothing is uploaded to a server — your work is saved locally, in this browser, on this device.

  • Clearing your browser data, or using private/incognito mode, will lose your work.
  • You won't see your diagrams on another device or in another browser.
  • To keep or move a diagram, use Export to save a file — and Import to open it again, anywhere.

Export anything you'd be annoyed to lose.

  • Shapes, containers, swimlanes & frames
  • Database tables with row-to-row keys
  • UML classes & mind-maps
  • Smart connectors with snapping
  • DBML + JSON import / export
  • Undo / redo, everything on the keyboard
