JointJS+ has allowed us to deliver top-notch features and complex mechanisms with ease. Its efficient documentation, fast implementation and great customer support was exactly what we were looking for.
Alon Doron
Software Engineer, NICE Systems Ltd.
The JointJS+ toolkit is the best solution we found as a full fledged diagramming library for the web. The JointJS team has been extremely responsive to our needs and it’s been great to help contribute back to the product throughout our development process.
Kevin Mansel
Senior Software Engineer, Patent Navigation
I worked with JointJS+ on different projects to build graphical editors and it helps me get off the ground quickly. Most of the features that you know from other modern editors, even the more advanced ones, are prebuilt in the framework and can be enabled with just a few lines of code. All other features can be added easily due to the framework‘s open nature. And if you get stuck, they provide excellent technical support where you can get in touch directly with the creators of the framework.
