Always follow the official "How to register licenses" guide for your specific framework (ASP.NET, .NET Core, Angular, React, Vue, WinForms, WPF).
While the license key must be included in the application bundle to function, developers must be cautious about repository exposure.
For large organizations or ISVs (Independent Software Vendors) embedding DevExtreme into a redistributable application.
Critical Note: There is no "free commercial license." The Community License is only for open-source projects or small businesses making under $1M USD annually (you must apply and be approved). devextreme license key
A common source of technical debt arises when developers transition from a trial version to a commercial license without properly removing trial artifacts. The trial version often displays watermark overlays on UI components.
Alternatively, for non-modular environments or specific legacy versions, the DevExpress.ui.setLicenseKey method may be utilized. This method accepts a string key as an argument, manually setting the license state.
Your local machine might work (thanks to cached credentials), but your CI/CD pipeline will fail with cryptic Evaluation period expired errors. Client-side (JavaScript/TypeScript web apps):
✅ Fix: Always set the license key via environment variable on the build server:
DEVEXTREME_LICENSE_KEY=DXv24.2...
Or inject it during the build step.
If you’ve started a new project with DevExtreme—the enterprise-grade UI component suite from DevExpress—you’ve likely hit that first practical hurdle: Where do I find my license key, and how do I actually use it? Desktop apps:
Unlike a simple SaaS subscription, DevExtreme licensing can feel a bit old-school (yes, there are .licx files involved). Let’s break it down so you can get back to building your Angular, React, Vue, or jQuery app.
Problem: CI/CD pipeline runs npm install but the license key isn’t persisted.
Solution: Store the license key as a secret environment variable (e.g., DEVEXTREME_KEY) and inject it during build:
LicenseManager.setLicenseKey(process.env.DEVEXTREME_KEY);
