For product designers, PMs, and engineers who need fast hand-drawn diagrams, flows, and lo-fi wireframe sketches—not hi-fi UI systems. Excalidraw gives an infinite canvas with full editor tools, link-based collaboration, and limited generative AI on the free forever tier. Prefer Figma for production UI, or Miro when you need full workshop facilitation—not a lightweight sketch board.
You want low-friction architecture, UX flow, or workshop sketches in a hand-drawn style—share a link and iterate without spinning up a heavy whiteboard suite.
Open the web app → sketch flows or frames → share a collab link → export PNG/SVG into docs or tickets. Stay Free for one-off scenes; upgrade to Plus when you need cloud libraries, team folders, Extended AI, or MCP for agent workflows. Keep production UI in Figma; use Excalidraw for the messy thinking layer.
