Excalidraw
Open-source virtual whiteboard with hand-drawn style for sketching diagrams, wireframes, and flowcharts collaboratively.
Excalidraw produces hand-drawn style diagrams, wireframes, and flowcharts with real-time collaboration. Its infinite canvas, shape library, and export-as-PNG/SVG features make it a lightweight alternative to heavy diagramming tools.
Great for engineers sketching architecture diagrams, product managers mapping user flows, and educators creating visual explanations. The hand-drawn aesthetic reduces the pressure of perfection and encourages iterative thinking.
