## What it is
Excalidraw is an open-source virtual whiteboard for creating hand-drawn style diagrams, wireframes, and sketches on an infinite canvas. It supports real-time collaboration with end-to-end encryption and is also available as an embeddable React npm package.

## Use cases
- sketch hand-drawn style diagrams and wireframes
- collaborate on a shared whiteboard in real time
- embed a whiteboard editor in a React app
- export diagrams to PNG or SVG
- create architecture and flow diagrams with arrows and labels
- share drawings as encrypted links

## When to choose
- you want a free, open-source whiteboard with a hand-drawn aesthetic
- you need end-to-end encrypted collaborative sketching
- you want to embed a customizable canvas editor in a web app
- you need an open JSON format for diagrams

## When to avoid
- you need precise CAD-style or UML-strict diagramming with validation
- you require heavy offline desktop features or advanced version control of drawings
- you need pixel-perfect professional graphics rather than sketch-style output
