What is it?

draw.io is a configurable diagramming and whiteboarding application that runs entirely in the browser as a client-side JavaScript editor. It is used for general-purpose diagrams such as flowcharts, architecture drawings and whiteboard sketches. The project is jointly developed by draw.io Ltd and draw.io AG, and the same codebase powers the hosted app at app.diagrams.net.

This repository is a test version intended for evaluating the editor. It can be run by publishing a fork to GitHub Pages, using a Docker image, or deploying the packaged .war files from the releases page. A desktop app is also available separately. Supported browsers include recent versions of Chrome, Firefox, Safari, Opera, Edge and mobile WebViews.

The project is not an SVG editor; SVG export is meant for embedding in web pages rather than editing in other tools. Real-time collaborative editing is not supported in this version, and the project does not accept pull requests from outside contributors.
