Excalidraw Has a Free Whiteboard — Draw Diagrams That Look Hand-Drawn

Excalidraw is a virtual whiteboard for creating diagrams that look hand-drawn — perfect for architecture diagrams, wireframes, and brainstorming.

What You Get for Free

• Hand-drawn style — diagrams that look human, not robotic
• Real-time collaboration — share a link, draw together
• Library — drag-and-drop shapes, icons, templates
• Export — PNG, SVG, clipboard, or embed in your app
• Offline — works without internet (PWA)
• Encryption — end-to-end encrypted collaboration
• Open source — self-host on your infrastructure
• Embeddable — React component for your app
• Dark mode — easy on the eyes

Quick Start

1. Open excalidraw.com (no signup)
2. Start drawing — rectangles, arrows, text
3. Share link for collaboration
4. Export as PNG/SVG

# Embed in React app
npm install @excalidraw/excalidraw

import { Excalidraw } from '@excalidraw/excalidraw'

function App() {
  return <Excalidraw />
}

Why Developers Switch from Miro/Lucidchart

Paid tools are overkill for technical diagrams:

• Free forever — no $8/user/month for drawing boxes
• Hand-drawn look — stakeholders love it (less "final" = more feedback)
• No signup — open URL, start drawing, share link
• Open source — embed in docs, apps, wikis

A team paid $96/month for Miro (12 users) to draw architecture diagrams. After Excalidraw: same diagrams, better aesthetic, $0/month. Shared via URL, no accounts needed.
