Some developers search for "gojs remove watermark" hoping to simply reset the trial period indefinitely. They download the GoJS trial, use it for a few weeks, and then attempt to delete cache, change system dates, or re-download the library.
Does this work?
No. The watermark in GoJS is not time-limited in the traditional sense. The trial version does not "expire" after 30 days. Instead, the watermark is always present in the trial distribution. It does not phone home to a server. The code that renders the watermark is compiled into the library. Resetting your system clock or clearing caches will have zero effect.
To remove the watermark, you essentially need to:
If you decide to ignore licensing and remove the watermark via hacking, here is what you risk: gojs remove watermark
| Consequence | Impact | | :--- | :--- | | Legal Liability | Northwoods Software actively tracks piracy. If your web app becomes popular, they will issue a cease & desist and demand back-licensing fees for every developer who touched the code. | | Broken Diagrams | Patched libraries often break with the next browser update (e.g., Chrome changing canvas rendering). Your production app will display broken lines, missing text, or nothing at all. | | No Support | When your diagrams break (and they will), Northwoods will refuse support. You will be left alone with a broken, hacked library. | | Bad for Your Reputation | Open-source or commercial software that relies on pirated GoJS cannot be legally distributed or audited. Investors and clients will walk away if they discover license violations. |

// Now create your diagram const myDiagram = new go.Diagram("myDiagramDiv");
That’s it. Once the key is applied, the watermark disappears instantly. No CSS hacks, no file editing.
If you are a developer working with interactive diagrams, flowcharts, or organizational charts in JavaScript, you have almost certainly encountered GoJS (Go GraphJS). Developed by Northwoods Software, GoJS is the gold standard for building complex, data-rich visualizations.
However, if you have ever used the unlicensed version of GoJS in a development environment—or accidentally deployed a trial version to production—you have seen it: the dreaded GoJS watermark. This semi-transparent overlay typically reads "Trial Version" or "GoJS Evaluation" and sits stubbornly on top of your beautiful diagrams. Some developers search for "gojs remove watermark" hoping
