Why Choose Northwoods?

A Long History

We've been creating diagram components for over 20 years, over many platforms, and reap the benefits of redesigning a library from scratch for each new platform while taking into account our accumulated experience.

The original code base was written for C++. As the underlying operating system platform evolved, Northwoods subsequently produced graphical editing libraries for Java (JGo), C#/.NET (GoDiagram), and C#/WPF (GoXam). Our latest diagramming library is for JavaScript/HTML5 Canvas (GoJS).

I have been super impressed with the excellent support team, who are very quick to respond and are always willing to help. Our customers are now able to use the design tool in any browser and on any device. Great company, excellent support, superb product. Would highly recommend. - Phil Bell, KCOM

Trusted Engineering Excellence

We started building diagramming libraries before all of our competitors, most of which have either gone out of business or stopped development. That holds true for open source projects as well; the principal(s) move on to other projects. Sometimes, newcomers try to continue the project, but that rarely works out in the long run. Interactive diagramming libraries are too much of a niche to have a large enough programmer base from which to find good contributors, yet the work is complex and demanding enough to require dedicated experience and skills.

Many open source projects offer no support. Those that do offer support charge extra for it. The prices are such that there is no price advantage in being open source. Source code is available, so that is not an advantage for open source either. You are investing in a quality product backed by over 100 combined years of software engineering experience.
