Gojs Remove Watermark Official
A: No. GoJS licenses are perpetual for a specific version. You pay once and own that version forever. Maintenance (updates) is optional yearly.
You purchased a license. You set go.GraphObject.licenseKey. But the watermark remains. Here is your debugging checklist:
Correct implementation pattern (React example):
import * as go from 'gojs';// GOOD: Set this immediately, outside any component go.GraphObject.licenseKey = process.env.REACT_APP_GOJS_LICENSE;
function MyDiagramComponent() useEffect(() => // The key is already set globally. const diagram = new go.Diagram("myDiv"); // ... rest of diagram setup , []);
If you arrived at this article via a Google search for "gojs remove watermark," bookmark the official Northwoods licensing page instead of a hacker forum. The 15 minutes it takes to get approval for a license purchase is infinitely less time than the weeks of debugging you will face with a cracked, unstable library.
Remove the watermark by writing this line:
go.GraphObject.licenseKey = "YOUR_OFFICIAL_KEY";
Everything else is just breaking the law and breaking your code.
In the neon-drenched sprawl of Neo-Veridia, code was currency, and efficiency was religion.
Elias was a "Schematic Priest," a senior frontend architect for the Omni-Corp. His job was to visualize the city’s chaotic data streams—logistics, power grids, neural networks—into coherent, interactive maps. For years, he had worshipped at the altar of GoJS, the legendary library that turned tangled messes of JSON into divine diagrams.
But there was a heresy in his code.
Every time Elias deployed a new visualization for the Board of Directors, the maps were perfect. The nodes glowed with recursive logic; the links pulsed with the heartbeat of the city’s trade routes. Yet, emblazoned across the center of every screen, floating like a ghost over the data, was the Stamp.
The Watermark.
It was a small, translucent text box, a digital scar that read: Unlicensed Evaluation Copy.
To the uninitiated, it was a minor annoyance. But to the Board, it was a sign of weakness. It screamed, "This architect does not own his tools."
"We have the budget, Elias," Director Kaelen snapped during the quarterly review, tapping the screen with a stylus. The stylus passed right through the holographic watermark, phasing through the word 'Evaluation.' "Why is this blemish still here? We paid for the Enterprise license."
Elias swallowed hard. "The procurement process is... lengthy, sir. I’m running the trial version while we wait for the keys."
"We are presenting to the Galactic Trade Federation in three hours," Kaelen said, his voice dropping to a dangerous whisper. "If they see 'Evaluation Copy' over our supply chain data, they’ll think we’re amateurs. Fix it. Remove the watermark." gojs remove watermark
Elias retreated to his terminal, the hum of the server farm surrounding him like white noise. He knew the rules. GoJS was open and honest. The documentation was clear: to remove the watermark, you had to purchase a license and input a valid license key in the code. He had submitted the paperwork weeks ago. Procurement was stuck in bureaucratic limbo.
He checked his inbox. Request Pending.
He didn't have the key.
"Damn it," he muttered. He looked at the clock. Two hours.
A notification pinged on a secure, shadow-net channel he kept open. It was a user named Cryptic_Coder.
Looking for a shortcut, Priest?
Elias stared at the message. He knew what Cryptic_Coder was offering. There were dark corners of the web where developers traded "cracked" versions of libraries. Scripts that stripped out the validation logic. Hex editors that binary-patched the minified JS files to bypass the license check.
It was the easy way out. But Elias knew the legend of the Northwoods. He knew that GoJS was guarded by ancient, swirling obfuscation magic. Tampering with the source code was a recipe for disaster. One wrong move, and the layout algorithms would collapse, turning his beautiful flowcharts into spaghetti.
"I don't need a crack," Elias typed back. "I need the real thing."
The real thing takes time. You have none.
Elias closed the chat. He wasn't a hacker; he was an architect. He looked at the code on his screen. He was using the latest version of the library. He scrolled through the documentation, desperate for a grace period, a hidden flag, something.
Then, he saw it. A small function in the API docs he
Removing the GoJS watermark is officially done by purchasing a license from Northwoods Software . The watermark appears when using the evaluation version Google Groups
Here is a summary of how to remove the GoJS watermark based on their deployment guidelines: 1. Purchase and Apply a License Key (Recommended)
For GoJS version 1.7 and later, you must use a license key provided after purchasing the software. Google Groups Apply the key:
Add the key to your code immediately after loading the GoJS library but before creating any diagrams. javascript // Example go.Diagram.licenseKey = "YOUR_LICENSE_KEY_HERE" Use code with caution. Copied to clipboard Deployment:
The watermark will disappear once you deploy your application to the domain registered with the license key. Northwoods Software 2. Localhost Development
If you are developing locally, the watermark should not appear if you are serving your page from A: No
To remove the watermark from a GoJS diagram, you must use a valid license key provided by Northwoods Software. This watermark is a built-in feature of the evaluation version, indicating that the software is not yet licensed for production use. Standard Method for Removing the Watermark
For GoJS version 1.7 and newer, the standard process involves activating a license key tied to your specific web domain.
Purchase a License: Obtain a commercial license from the Northwoods Software pricing page. Options range from individual licenses ($3,995) to team licenses.
Request a License Key: Once purchased, go to the GoJS activation page to generate a key for your domain.
Apply the Key in Code: Before initializing any go.Diagram, set the go.licenseKey property with your generated string: javascript
go.licenseKey = "YOUR_LICENSE_KEY_HERE"; var myDiagram = new go.Diagram("myDiagramDiv", ... ); Use code with caution.
Serve from the Correct Domain: The watermark will only disappear if the page is served from the exact domain tied to your license key. Specialized Deployment Scenarios
If your application does not run on a standard web domain (e.g., local files or desktop wrappers), the licensing requirements change:
Desktop Applications: For apps built with Electron or Cordova, there is no domain to tie a key to. In these cases, you must use the Unlimited Domains license option.
Version 1.6 and Older: These older versions require a custom-generated go.js or go-debug.js library file rather than a simple license key. Legal and Ethical Considerations
GoJS is not open-source; it is proprietary software with a strict Software Evaluation License Agreement. Gojs Remove Watermark - Google Groups
To remove the GoJS watermark, you must assign a valid license key to the go.Diagram.licenseKey property before creating any diagrams. Quick Steps to Remove Watermark Obtain a Key: Purchase a license from Northwoods Software.
Set the Property: Add the following line to your code before diagram initialization:go.Diagram.licenseKey = "YOUR_KEY_HERE";.
Match Versions: Ensure your license key matches the major and minor version of the library you are using (e.g., a 2.1 key won't work for version 2.2).
Check Domain: The watermark may reappear if the domain serving the page does not match the one registered with the key. 💡 Troubleshooting Common Issues
Localhost vs. Production: The watermark often disappears on localhost but reappears on live servers if the key is missing or domain-locked.
Major Updates: If you recently upgraded GoJS (e.g., from 1.x to 2.x), you usually need to request a new license key from the Product Activation page.
High Contrast Mode: In rare cases, Windows "High Contrast" settings can cause the watermark to show even with a valid key. Correct implementation pattern (React example): import * as
Salesforce/LWC: Ensure the key is set globally on the window.go object within your component lifecycle. Warning on Unofficial Methods
While some forum posts suggest modifying the source code (like commenting out specific internal functions), this is not recommended for production. It violates the Terms of Service.
Minified code changes with every update, making manual fixes brittle.
Official keys are the only supported way to ensure a clean UI.

The most common method is replacing the evaluation script with the licensed script.
GoJS, developed by Northwoods Software, offers a fully functional evaluation version. To distinguish unlicensed usage, the library displays a small watermark — usually "Evaluation" or "© Northwoods Software" — on diagrams rendered in a browser. This watermark is not a bug or an oversight; it is an intentional mechanism that protects the software creator's rights while allowing developers to test functionality before purchase.
If you are a software developer, data visualization engineer, or product manager, you have likely encountered GoJS. It is arguably the most powerful JavaScript library for interactive diagrams, flowcharts, and organizational charts. However, if you are using the unlicensed version, you have also encountered the infamous GoJS watermark: a small (but persistent) text stamp that reads “Evaluation” or displays a copyright notice in the corner of every diagram.
Searching for “gojs remove watermark” is a common reflex. Developers want clean, professional outputs without paying immediately. But here is the hard truth: GoJS is proprietary software. Unlike open-source libraries (e.g., D3.js or Three.js), GoJS requires a commercial license for production use.
In this 2,500+ word guide, we will explore every legitimate method to remove the GoJS watermark, why the watermark exists, the dangers of "cracked" scripts, and how to obtain a legal, clean license.
After including the go.js or go-debug.js script, initialize the license key before creating any diagrams.
JavaScript Example:
// IMPORTANT: Set this BEFORE creating any Diagram or Part go.licenseKey = "YOUR_PURCHASED_LICENSE_KEY_HERE";
// Now create your diagram const myDiagram = new go.Diagram("myDiagramDiv"); // The watermark will be GONE.
TypeScript/Angular/React Example:
import * as go from 'gojs';// Set the key globally (go as any).licenseKey = "YOUR_LICENSE_KEY";
// Proceed with diagram initialization const diagram = new go.Diagram("diagramDiv");
Verification: Once the license key is set correctly, the “Evaluation” text will disappear immediately. No additional CSS hacks or DOM manipulation is required.
