Developers seeking watermark-free diagramming solutions should either budget for GoJS licensing or explore legitimate open-source alternatives. Respecting software licenses ultimately supports a healthy ecosystem where developers can continue creating high-quality tools.
The licensing model of GoJS is competitive and reflects the value it brings to development projects. The additional features, support, and the ability to legally use the diagrams in commercial projects are significant advantages.
Some keys require a special configuration or separate local key to run smoothly on localhost during development.
