The app hosted at excalidraw.com is a minimal showcase of what you can build with Excalidraw. Its source code is part of this repository as well, and the app features:

• 📡 PWA support (works offline).
• 🤼 Real-time collaboration.
• 🔒 End-to-end encryption.
• 💾 Local-first support (autosaves to the browser).
• 🔗 Shareable links (export to a readonly link you can share with others).

We’ll be adding these features as drop-in plugins for the npm package in the future.
