Updated October 1, 2026

Lux is a Lit-based platform for building widget-based UI experiences that run on a ServiceNow instance. You create pages using widgets as Lit components. Release notes are organized by version.

## About Lux {#lux-rn__lux-rn-about}

* Build widget-based UI experiences that run on your instance, using Lit components for pages and widgets.
* Render pages on the server and stream the HTML to the browser, which hydrates it into an interactive single-page app.
* Show fully rendered content on first load, with markup that assistive technology and search engines can read.
* Fetch data on the server with loaders that run near your instance.
* Map your pages directory to URLs with file-based routing.
* Inherit the design system automatically through Tailwind and DaisyUI styling.
* Share data across widgets with the Context API, and across pages with layout data.
* Deploy your scoped application to an instance on its own schedule with the ServiceNow SDK.
