- A free online diagram software for making flowcharts, process diagrams, org charts, UML, ER and network diagrams.
- It can store images as XML files or SVG which is very useful when it comes to version control.
- It can also be used offline as a desktop application.
- It has a VS Code extension which allows you to edit draw.io files directly in Visual Studio Code. > Note: I’ve found the Visual Studio Code extension to be a bit buggy, so I recommend using the online or desktop version instead.
Personally I’ve used it to make block diagrams that describe the business logic of a system, and it was very helpful and easy to use.
