</table>## Key benefits of Lux

-   Admin configuration changes survive platform upgrades
-   Extend or override another app's experience without forking it or coordinating release schedules
-   Users see content instantly with no spinners, and search engines can index the fully rendered markup
-   Lux applies design system styling and theming automatically, letting admins override tokens per tenant without a rebuild
-   Build components and widgets once and reuse across pages, apps, AI placement, and chat surfaces
-   One consistent build-deploy pipeline and architecture across the CLI, Lux Lab, and Maven, regardless of app size
