draw.io is an online diagramming web site that delivers the source in this project.

draw.io uses the mxGraph library as the base of the stack, with the GraphEditor example from mxGraph as the base of the application part. The mxGraph library build used is stored under /etc/mxgraph/mxClient.js.

draw.io is licensed under the GPL v3.

A development guide is being started on the GitHub project wiki. There is a draw.io tag on Stack Overflow currently, please make sure any questions adhere to their guidelines for question.

The mxGraph documentation provides a lot of the docs for the bottom part of the stack. There is an mxgraph tag on SO.

The simplest way to run draw.io initially is to fork this project, publish the master branch to GitHub pages and the pages sites will have the full editor functionality (sans the integrations).

The full packaged .war of the client and servlets is built when the project is tagged and available on the releases page.

draw.io supports IE 11, Chrome 32+, Firefox 38+, Safari 7.1.x, 8.0.x, 9.1.x and 10.0.x, Opera 20+, Native Android browser 5.1.x+, the default browser in the current and previous major iOS versions (e.g. 10.x and 9.x) and Edge 23+.
