yEd is a powerful desktop application that can be used to quickly and effectively generate high-quality diagrams.
Create diagrams manually, or import your external data for analysis. Our automatic layout algorithms arrange even large data sets with just the press of a button.
I’ve just recently sat in an meeting with application development talking roadmap and architecture and was curious what tool they used diagramming their workflows and service dependencies. When the manager mentioned this tool, I was suprised to hear it wasn’t Visio.
yEd is freely available and runs on all major platforms: Windows, Unix/Linux, and Mac OS X.
