XMLUI is a framework for building user interfaces declaratively, with XML markup and flexible theming.

Easy to create. Build on the web platform with little or no knowledge of React or CSS.

Clean and modern. Enjoy themes that look great out of the box and are easy to modify. Create experiences that meet expectations for modern web apps.

Connected. Read and write APIs with little or no scripting.

Modular. Use a comprehensive suite of components that you can extend with — again! — little or no scripting.

Easy to deploy. Just drop a handful of files onto a static webserver.

<App>
  <Select id="lines" initialValue="bakerloo">
    <Items data="https://api.tfl.gov.uk/line/mode/tube/status">
        <Option value="{$item.id}" label="{$item.name}" />
    </Items>
  </Select>
  <DataSource
    id="tubeStations"
    url="https://api.tfl.gov.uk/Line/{lines.value}/Route/Sequence/inbound"
    resultSelector="stations"/>
  <Table data="{tubeStations}" height="280px">
    <Column bindTo="name" />
    <Column bindTo="modes" />
  </Table>
</App>

The fastest way to get started with XMLUI is to download our starter kit, which includes the XMLUI engine and XMLUI Invoice - a complete business application that demonstrates key features and common patterns.

XMLUI Invoice: A complete business application with client and product management, invoice creation and tracking, search, and charts.

XMLUI engine: The core framework file.

XMLUI test server: A simple server to run the app.

Extract the files to a working folder and run the start script.

XMLUI was stared as an internal project at /n software which is the primary sponsor and source of funding for this open source project.

Our virtualized components and data management mechanisms would not be as simple, performant, and powerful without the help of a few TanStack projects, such as query, table, and others. We appreciate their outstanding work!

We based some of our essential components on Radix UI components and involved some of the architectural approaches they used in their project. Thanks to all project contributors for their excellent work.

We loved the simple and beautiful UI style used by the Tabler.io project; it illuminated our component design and theming. Thanks to Paweł Kuna for this inspiration.
