Excalidraw

Excalidraw Free Beginner

A free, no signup whiteboard with a deliberately hand drawn look, ideal for sketching screens and flows without falling into pixel perfect design. The rough style keeps everyone focused on structure and the user's path, which is the point of a version one sketch. You can share a link with your developer in seconds and mark up ideas together.

  • Sketch screens and arrows between them in minutes, no account needed
  • The hand drawn look keeps the focus on flow, not visual polish
  • Share a live link so a developer can annotate with you
