yEd — Powerful free app for generating high-quality diagrams

I have been a long time user of yEd, love it, have used to to make simple flow charts, architecture diagrams and more. It can have a small learning curve, but is pretty simple to use once you get the hold of it .

One thing I loved about using yEd back in my days at Red Hat (where I avoided using only the Mac-based tools my Linux-only colleagues wouldn't use) were the awesome Swimlanes templates. So many similar product skip this, and it's such an essential part of my workflow as a product manager that I often went to yEd just for this. As a small request, I do wish they would ramp up the quality of the UI and overall UX and compete with the likes of Omnigraffle, or just open source it however.

Looks like a very thorough product.
