The cost of a GoJS license should be considered in the context of the value the library provides. GoJS offers extensive functionality for building complex interactive diagrams, including support for drag-and-drop, copy-paste, text editing, tooltips, context menus, automatic layouts, templates, data binding, transaction management, palette components, event handlers, and an extensible command system. Building equivalent functionality from scratch would involve enormous development time and expense.
Some developers have even created patches and scripts to automate this process, or used tools like patch-package to persist the modifications across npm installs.
Once the licenseKey property matches the domain name or application ID where the script is executing, the GoJS engine automatically suppresses the rendering of the watermark text on the canvas. Troubleshooting Common Watermark Issues
The most common method is replacing the evaluation script with the licensed script.
: In environments like Salesforce Lightning Web Components (LWC), ensure the license key is set globally or early enough in the lifecycle for the library to recognize it. Unofficial/Workaround Methods (Development Only)

: The watermark will only disappear if the page is served from the exact domain tied to your license key. Specialized Deployment Scenarios
GoJS is proprietary software. Using unauthorized workarounds to hide or strip the watermark in a production environment violates the End User License Agreement (EULA) and can expose your organization to legal risks. Steps to Acquire a License Key

You must inject the license key into your application before initializing any diagrams. Call the go.Diagram.licenseKey property immediately after loading the GoJS library. Standard JavaScript Syntax javascript
