Many thanks for the message, I'm really glad you're getting value from yUML.I understand your concerns. We used to sell an enterprise license where source code could be modified and but not re-sold. This was a little clunky to roll out but does help some enterprises. Perhaps we could evaluate that for your organisation?yUML was launched in 2008 and my company in 2012 (Pocketworks, UK App Developers). We work on yUML every year and have no plans to sunset it.However, if you're interested in the enterprise license please contact tobin @ pocketworks.co.uk and I'll see what we can do.Thanks!P.S - Would be awesome to hear how you're using yUML.

We built a vast framework around yuml. With that said, we are very concerned about the longevity and the future of yuml as things may change. Basically, what is the exit strategy should we need diagrams and servers are no longer available? This would mean recreating and writing new code to support a different platform which would be costly for us if a portable client side option is not available.
