Diagrams.net (formerly draw.io) is a powerfull app designed to create diagrams and flowcharts.

There are many ways to use it: online without installation and packages for Windows, Mac and Linux are available are available. Iintegrations in VSCode, Nextcloud, Redmine and others can be found in the documentation.

Here is how to import additionnal icons to your Librairies, and pick them directly from the sidebar.

Let’s use Font Awesome for example (see below for more icon sets)

  • in the bottom-right corner, select “All files”:

  • double-click on the color set you want to use. Note that I didn’t find a way to modify icon color after that step.

That’s it!

You can now pick any icon from the sidebar:

Unfortunately Diagrams.net does not support importation of Font files. But several icon sets have already been packaged:
