yEd Graph Editor

One of the best tools for diagram/flow design I ever used. Congratulations for the developers because of the great product quality and for the free release initiative.

Well, for mindmapping there's MindManager, but for every other graph without any centredness (like mindmapping suggests) this is THE tool. I've tried many others but this is absolutely on top. 1. Free. 2. Lot's of options available (lacks of curving text along relationship arrows, but who cares!) 3. Can export SVG or EPS, which means any vector format.

I was going to support 'em with some paypal cash 'coz they deserve it 100%, but never found a link.

I tried them 'all', but this program has some features i have not seen before: * really flexible connection points, which stay in place the way you want * setting properties (like width/height) for more than one item at once

And it can export to non-proprietry formats as well.

Works great for me

but else I don't think very highly of it. It's lacks kind of in sexyness, or to put in other words the graphs and UML you are drawing are very simple and not good looking, nothing you like to show a client. But between programmers it is a good choice, well it is free and everybody can get it...

I can see a lot of good things in this software. However I use a mac and does not use any of the conventions that apply for Mac OSX software. It installs like windows software and puts a shortcut on the desktop!!! When I click the red X the program shuts down. I can't recommend it for mac users.

Though it's still not better than Visio, it's rather impressive and runs well on Linux.

This is an amazing piece of software. The best I have used. I've used several methods of making diagrams, such as with Dia, Diagram Designer, Edge Diagram, Smart Draw, Microsoft Office, Inkscape,an online program whose name I can't remember, etc, etc, and this is the best I've seen,
