JointJS+ allowed CELUS to focus all our efforts on developing our core technology, while still providing our users with a great diagramming experience. The library is fast to integrate and comes with a wide set of advanced features out of the box that saved us countless development hours. A great partner to have!

JointJS+ was really a great find, as it gave us a great boost in the diagramming frontend of our application. These guys know their business and give you a great support on your development. One of our requirements was to have a BPMN diagram support in our app and they quickly supplied this as a plugin to JointJS+!
