- Rich drawing tools (shapes, arrows, free-draw, text, eraser) with undo/redo
- Arrow binding and labeled connectors for clearer diagrams
- Real-time collaboration with end-to-end encryption support
- Local-first behavior (autosave in the browser) and offline-capable PWA
- Export and sharing options (PNG, SVG, clipboard, and open JSON-based file format)
- Image support, theming (including dark mode), and localization (i18n)
Use Cases
- Team brainstorming sessions and collaborative whiteboarding
- Creating lightweight architecture diagrams, flowcharts, and user journey maps
- Wireframing UI concepts and embedding a whiteboard into other web apps
Excalidraw works well as a standalone web app or as a reusable component via its editor package. It is a strong choice for teams and individuals who want quick, low-friction diagramming without heavy tooling.
