Excalidraw

Excalidraw is a virtual whiteboard for sketching hand-drawn-like diagrams with a focus on simplicity and speed. The open-source tool provides infinite canvas, real-time collaboration, and a unique hand-drawn aesthetic that makes diagrams feel approachable and informal - perfect for quick sketches, brainstorming, and technical diagrams that don't need corporate polish.

Best For: Quick diagramming and sketching with hand-drawn aesthetic, remote team collaboration on informal diagrams, and anyone who wants simple whiteboarding without accounts or complexity.
